Organization, Consolidation and Presentation of Financial Statements [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES | NOTE 1 - BASIS OF PRESENTATION AND SIGNIFICANT ACCOUNTING POLICIES The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with SEC rules and regulations and, in the opinion of management, include all adjustments (consisting of normal recurring adjustments) necessary to present fairly the financial position, results of operations, comprehensive income and cash flows for the periods presented. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Management bases its estimates on various assumptions and historical experience, which are believed to be reasonable; however, due to the inherent nature of estimates, actual results may differ significantly due to changed conditions or assumptions. The results of operations for the three and six months ended June 30, 2018 are not necessarily indicative of results to be expected for the year ending December 31, 2018 or any other future period. These unaudited condensed consolidated financial statements should be read in conjunction with the financial statements and notes included in our Annual Report on Form 10-K for the year ended December 31, 2017. As more fully described in NOTE 16 - DISCONTINUED OPERATIONS, on January 25, 2018, we announced that we would accelerate the time frame for the planned closure of our Asia Pacific Iron Ore mining operations in Australia. On April 6, 2018, we committed to a course of action leading to the permanent closure of the Asia Pacific Iron Ore mining operations and, as planned, completed our final shipment in June 2018. Factors considered in this decision included increasingly discounted prices for lower-iron-content ore and the quality of the remaining iron ore reserves. During June 2018, we completed a sale of the mobile equipment to a third party and entered into a definitive agreement to sell substantially all of the remaining assets of our Asia Pacific Iron Ore business to Mineral Resources Limited. The sale to Mineral Resources Limited has not been completed as of the date of this report due to the pendency of certain closing conditions. As a result, for the period ended June 30, 2018, management determined that our Asia Pacific Iron Ore operating segment met the criteria to be classified as held for sale and a discontinued operation under ASC 205, Presentation of Financial Statements. As such, all current and historical Asia Pacific Iron Ore operating segment results are included in our financial statements and classified within discontinued operations. We now operate in one reportable segment – U.S. Iron Ore. Unless otherwise noted, discussion of our business and results of operations in this Quarterly Report on Form 10-Q refers to our continuing operations. Basis of Consolidation The unaudited condensed consolidated financial statements include our accounts and the accounts of our wholly-owned subsidiaries, including the following operations as of June 30, 2018:
Intercompany transactions and balances are eliminated upon consolidation. Equity Method Investments Our 23% ownership interest in Hibbing is recorded as an equity method investment. As of June 30, 2018 and December 31, 2017, our investment in Hibbing was $8.0 million and $11.0 million, respectively, classified as Other liabilities in the Statements of Unaudited Condensed Consolidated Financial Position. Foreign Currency Our financial statements are prepared with the U.S. dollar as the reporting currency. The functional currency of our Australian subsidiaries is the Australian dollar. Refer to NOTE 16 - DISCONTINUED OPERATIONS for further information regarding our Australian subsidiaries. The functional currency of all other international subsidiaries is the U.S. dollar. To the extent that monetary assets and liabilities, including short-term intercompany loans, are recorded in a currency other than the functional currency, these amounts are remeasured each reporting period, with the resulting gain or loss being recorded in the Statements of Unaudited Condensed Consolidated Operations. Transaction gains and losses resulting from remeasurement of short-term intercompany loans are included in Miscellaneous – net in the Statements of Unaudited Condensed Consolidated Operations. The following represents the transaction gains and losses resulting from remeasurement:
Significant Accounting Policies A detailed description of our significant accounting policies can be found in the audited financial statements for the fiscal year ended December 31, 2017 included in our Annual Report on Form 10-K filed with the SEC. There have been no material changes in our significant accounting policies and estimates from those disclosed therein other than those related to the adoption of Topic 606. Refer to NOTE 2 - NEW ACCOUNTING STANDARDS for further information. |

NEW ACCOUNTING STANDARDS | NOTE 2 - NEW ACCOUNTING STANDARDS Adoption of New Accounting Standards ASC Topic 606, Revenue from Contracts with Customers (Topic 606). On January 1, 2018, we adopted Topic 606 and applied it to all contracts that were not completed using the modified retrospective method. We recognized the cumulative effect of initially applying Topic 606 as an adjustment of $34.0 million to the opening balance of Retained deficit. The comparative period information has not been restated and continues to be reported under the accounting standards in effect for those periods. We do not expect that the adoption of Topic 606 will have a material impact to our annual net income on an ongoing basis. Under Topic 606, revenue will generally be recognized upon delivery to our customers, which is earlier than under the previous guidance. As an example, for certain iron ore shipments where revenue was previously recognized upon title transfer when payment was received, we will now recognize revenue when control transfers, which is generally upon delivery. While we continue to retain title until we receive payment, we determined upon review of our customer contracts that the preponderance of control indicators pass to our customers' favor when we deliver our products; thus, we generally concluded that control transfers at that point. As a result of the adoption of Topic 606 and vessel deliveries not occurring during the winter months because of the closure of the Soo Locks and the Welland Canal, our revenues and net income will be relatively lower than historical levels during the first quarter of each year and relatively higher than historical levels during the remaining three quarters in future years. However, the total amount of revenue recognized during the year should remain substantially the same as under previous accounting standards, assuming revenue rates and volumes are consistent between years. The cumulative effect of the changes made to our consolidated January 1, 2018 balance sheet for the adoption of Topic 606 were as follows:
The impact of adoption on our Statements of Unaudited Condensed Consolidated Operations and Statements of Unaudited Condensed Consolidated Financial Position is as follows:
The adoption of Topic 606 did not have an impact on net cash flows in our Statements of Unaudited Condensed Consolidated Cash Flows. ASU 2017-07, Retirement Benefits - Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost. On January 1, 2018, we adopted the amendments to ASC 715 regarding the presentation of net periodic pension and postretirement benefit costs. We retrospectively adopted the presentation of service cost separate from the other components of net periodic costs. The interest cost, expected return on assets, amortization of prior service costs, net remeasurement, and other costs have been reclassified from Cost of goods sold and operating expenses, Selling, general and administrative expenses and Miscellaneous – net to Other non-operating income. We elected to apply the practical expedient, which allows us to reclassify amounts disclosed previously in our pension and other postretirement benefits footnote as the basis for applying retrospective presentation for comparative periods. On a prospective basis, only service costs will be included in amounts capitalized in inventory or property, plant, and equipment. The effect of the retrospective presentation change related to the net periodic cost of our defined benefit pension and other postretirement employee benefits plans on our Statements of Unaudited Condensed Consolidated Operations was as follows:
Recent Accounting Pronouncements Issued and Not Effective In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842). The new standard requires lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases except for short-term leases. For lessees, leases will continue to be classified as either operating or finance leases in the Statements of Unaudited Condensed Consolidated Operations. We plan to adopt the standard on its effective date of January 1, 2019. The new standard may be adopted using either the modified retrospective approach, which requires application of the new guidance at the beginning of the earliest comparative period presented or the optional alternative approach, which requires application of the new guidance at the beginning of the standard's effective date. We have finalized our implementation plan and have compiled an inventory of our existing leases. Based on our analysis to date, the updated standard is not expected to have a material effect on our consolidated financial statements. For example, based on the future minimum payments under non-cancellable operating leases as of June 30, 2018, we would expect to record approximately $16 million, discounted to fair value, in the Statements of Unaudited Condensed Consolidated Financial Position. |

Segment Reporting Disclosure [Text Block] | NOTE 3 - SEGMENT REPORTING We operate in one reportable segment – U.S. Iron Ore. U.S. Iron Ore is a major supplier of iron ore pellets to the North American steel industry from our mines and pellet plants located in Michigan and Minnesota. We evaluate segment performance based on sales margin, defined as revenues less cost of goods sold and operating expenses identifiable to each segment. Additionally, we evaluate performance on a segment basis, as well as a consolidated basis, based on EBITDA and Adjusted EBITDA. These measures allow management and investors to focus on our ability to service our debt as well as illustrate how the business and each operating segment are performing. Additionally, EBITDA and Adjusted EBITDA assist management and investors in their analysis and forecasting as these measures approximate the cash flows associated with operational earnings. The following tables present a summary of our reportable segment including a reconciliation of segment sales margin to Income from Continuing Operations Before Income Taxes and a reconciliation of Net Income to EBITDA and Adjusted EBITDA:

Revenue from Contract with Customer [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Revenue from Contract with Customer [Text Block] | NOTE 4 - REVENUE We sell a single product, iron ore pellets, in the North American market. Revenue is recognized generally when iron ore is delivered to our customers. Revenue is measured at the point that control transfers and represents the amount of consideration we expect to receive in exchange for transferring goods. We offer standard payment terms to our customers, generally requiring settlement within 30 days. We enter into supply contracts of varying lengths to provide customers iron ore pellets to use in their blast furnaces. Blast furnaces run continuously with a constant feed of iron ore and once shut down, cannot easily be restarted. As a result, we ship iron ore in large quantities for storage and use by customers at a later date. Customers do not simultaneously receive and consume the benefits of the iron ore. Based on our assessment of the factors that indicate the pattern of satisfaction, we transfer control of the iron ore at a point in time upon shipment or delivery of the product. The customer is able to direct the use of, and obtain substantially all of the benefits from, the product at the time the product is delivered. Certain of our customer supply agreements specify a provisional price, which is used for initial billing and cash collection. Revenue recorded in accordance with Topic 606 is calculated using the expected revenue rate at the point when control transfers. The final settlement includes market inputs for a specified period of time, which may vary by customer, but typically include one or more of the following: Platts 62% Price, pellet premiums, Platts international indexed freight rates and changes in specified Producer Price Indices, including industrial commodities, energy and steel. Changes in the expected revenue rate from the date control transfers through final settlement of contract terms is recorded in accordance with ASC Topic 815. Refer to NOTE 15 - DERIVATIVE INSTRUMENTS for further information on how our estimated and final revenue rates are determined. A supply agreement with a customer provides for supplemental revenue or refunds based on the average annual daily market price for hot-rolled coil steel at the time the iron ore is consumed in the customer’s blast furnaces. As control transfers prior to consumption, the supplemental revenue is recorded in accordance with ASC Topic 815. Refer to NOTE 15 - DERIVATIVE INSTRUMENTS for further information on supplemental revenue or refunds. Included within Revenues from product sales and services is derivative revenue related to ASC Topic 815 of $154.7 million and $198.5 million, for three and six months ended June 30, 2018, respectively. Practical expedients and exemptions We have elected to treat all shipping and handling costs as fulfillment costs because a significant portion of these costs are incurred prior to control transfer. We have various long-term sales contracts with minimum purchase and supply requirement provisions that extend beyond the current reporting period. The portion of our transaction price for these contracts that is allocated entirely to wholly unsatisfied performance obligations is based on market prices that have not yet been determined and therefore is variable in nature. As such, we have not disclosed the value of unsatisfied performance obligations pursuant to the practical expedient. Deferred Revenue The table below summarizes our deferred revenue balances:
The terms of one of our pellet supply agreements required supplemental payments to be paid by the customer during the period 2009 through 2012, with the option to defer a portion of the 2009 monthly amount in exchange for interest payments until the deferred amount was repaid in 2013. Installment amounts received under this arrangement in excess of sales were classified as Other current liabilities and Other liabilities in the Statements of Unaudited Condensed Consolidated Financial Position upon receipt of payment. Revenue is recognized over the life of the supply agreement, which extends until 2022, in equal annual installments. As of June 30, 2018 and December 31, 2017, installment amounts received in excess of sales totaled $59.9 million and $64.2 million, respectively, related to this agreement. As of June 30, 2018 and December 31, 2017, deferred revenue of $12.8 million was recorded in Other current liabilities and $47.1 million and $51.4 million, respectively, was recorded as long-term in Other liabilities in the Statements of Unaudited Condensed Consolidated Financial Position, related to this agreement. Due to the payment terms and the timing of cash receipts near a period end, cash receipts can exceed shipments for certain customers. Revenue recognized on these transactions totaling $7.2 million and $9.6 million was deferred and included in Other current liabilities in the Statements of Unaudited Condensed Consolidated Financial Position as of June 30, 2018 and December 31, 2017, respectively. |

DEBT AND CREDIT FACILITIES | NOTE 7 - DEBT AND CREDIT FACILITIES The following represents a summary of our long-term debt:
$1.075 Billion 5.75% 2025 Senior Notes On February 27, 2017, we entered into an indenture among the Company, the guarantors party thereto and U.S. Bank National Association, as trustee, relating to the issuance of $500 million aggregate principal amount of 5.75% 2025 Senior Notes. On August 7, 2017, we issued an additional $575 million aggregate principal amount of our 5.75% 2025 Senior Notes. The second tranche was issued at 97.0% of face value. The 5.75% 2025 Senior Notes were originally issued in private transactions exempt from the registration requirements of the Securities Act. Pursuant to the registration rights agreement executed as part of these issuances, we filed on February 14, 2018 a registration statement with the SEC with respect to a registered offer to exchange the 5.75% 2025 Senior Notes for publicly registered notes, with all significant terms and conditions remaining the same. The exchange offer expired on April 26, 2018, and substantially all of the outstanding 5.75% 2025 Senior Notes were tendered for exchange.

The ABL Facility will mature upon the earlier of February 28, 2023 or 60 days prior to the maturity of certain other material debt, and provides for up to $450.0 million in borrowings, comprised of (i) a $400.0 million U.S. tranche, including a $248.8 million sublimit for the issuance of letters of credit and a $100.0 million sublimit for U.S. swingline loans, and (ii) at the time of closing, a $50.0 million Australian tranche, including a $24.4 million sublimit for the issuance of letters of credit and a $20.0 million sublimit for Australian swingline loans. On June 19, 2018, the Australian tranche was terminated and reallocated to the U.S. tranche, resulting in a $450.0 million allocation to the U.S. tranche, including a $273.2 million sublimit for the issuance of letters of credit and $120.0 million sublimit for swingline loans. Availability under the U.S. tranche of the ABL Facility is limited to an eligible U.S. borrowing base, as applicable, determined by applying customary advance rates to eligible accounts receivable, inventory and certain mobile equipment. The ABL Facility and certain bank products and hedge obligations are guaranteed by us and certain of our existing wholly-owned U.S. subsidiaries and are required to be guaranteed by certain of our future U.S. subsidiaries. Amounts outstanding under the ABL Facility are secured by (i) a first-priority security interest in the accounts receivable and other rights to payment, inventory, as-extracted collateral, certain investment property, deposit accounts, securities accounts, certain general intangibles and commercial tort claims, certain mobile equipment, commodities accounts, deposit accounts, securities accounts and other related assets of ours, the other borrowers and the guarantors, and proceeds and products of each of the foregoing (collectively, the “ABL Collateral”) and (ii) a second-priority security interest in substantially all of our assets and the assets of the other borrowers and the guarantors other than the ABL Collateral (collectively, the “Notes Collateral” and, together with the ABL Collateral, the “Collateral”). Borrowings under the ABL Facility bear interest, at our option, at a base rate or, if certain conditions are met, a LIBOR rate, in each case plus an applicable margin. The base rate is equal to the greater of the federal funds rate plus ½ of 1%, the LIBOR rate based on a one-month interest period plus 1% and the floating rate announced by Bank of America Merrill Lynch as its “prime rate" and 1%. The LIBOR rate is a per annum fixed rate equal to LIBOR with respect to the applicable interest period and amount of LIBOR rate loan requested. The ABL Facility contains customary representations and warranties and affirmative and negative covenants including, among others, covenants regarding the maintenance of certain financial ratios if certain conditions are triggered, covenants relating to financial reporting, covenants relating to the payment of dividends on, or purchase or redemption of, our capital stock, covenants relating to the incurrence or prepayment of certain debt, covenants relating to the incurrence of liens or encumbrances, covenants relating to compliance with laws, covenants relating to transactions with affiliates, covenants relating to mergers and sales of all or substantially all of our assets and limitations on changes in the nature of our business. The ABL Facility provides for customary events of default, including, among other things, the event of nonpayment of principal, interest, fees, or other amounts, a representation or warranty proving to have been materially incorrect when made, failure to perform or observe certain covenants within a specified period of time, a cross-default to certain material indebtedness, the bankruptcy or insolvency of the Company and certain of its subsidiaries, monetary judgment defaults of a specified amount, invalidity of any loan documentation, a change of control of the Company, and ERISA defaults resulting in liability of a specified amount. If an event of a default exists (beyond any applicable grace or cure period, if any), the administrative agent may and, at the direction of the requisite number of lenders, shall declare all amounts owing under the ABL Facility immediately due and payable, terminate such lenders’ commitments to make loans under the ABL Facility and/or exercise any and all remedies and other rights under the ABL Facility. For certain events of default related to insolvency and receivership, the commitments of the lenders will be automatically terminated and all outstanding loans and other amounts will become immediately due and payable. As of June 30, 2018 and December 31, 2017, we were in compliance with the ABL Facility liquidity requirements and, therefore, the springing financial covenant requiring a minimum fixed charge coverage ratio of 1.0 to 1.0 was not applicable. As of June 30, 2018 and December 31, 2017, no loans were drawn under the ABL Facility and we had total availability of $400.3 million and $273.2 million, respectively, as a result of borrowing base limitations. As of June 30, 2018 and December 31, 2017, the principal amount of letter of credit obligations totaled $39.5 million and $46.5 million, respectively, to support business obligations primarily related to workers compensation and environmental obligations, thereby further reducing available borrowing capacity on our ABL Facility to $360.8 million and $226.7 million, respectively. |

FAIR VALUE MEASUREMENTS | NOTE 8 - FAIR VALUE MEASUREMENTS The following represents the assets and liabilities measured at fair value:
Financial assets classified in Level 1 include money market funds and treasury bonds. The valuation of these instruments is based upon unadjusted quoted prices for identical assets in active markets. The valuation of financial assets and liabilities classified in Level 2 is determined using a market approach based upon quoted prices for similar assets and liabilities in active markets or other inputs that are observable. Level 2 assets include commercial paper, certificates of deposit and commodity hedge contracts. Level 2 liabilities include commodity hedge contracts. The Level 3 assets and liabilities include derivative assets that consist of freestanding derivative instruments related to a customer supply agreement and certain provisional pricing arrangements with our customers. The supply agreement included in our Level 3 assets includes provisions for supplemental revenue or refunds based on the average annual daily market price for hot-rolled coil steel at the time the iron ore product is consumed in the customer’s blast furnaces. We account for these provisions as derivative instruments at the time of sale and adjust the corresponding asset or liability to fair value as an adjustment to Product revenues each reporting period until the product is consumed and the amounts are settled. The fair value of the instruments are determined using a market approach based on the estimate of the average annual daily market price for hot-rolled coil steel. This estimate takes into consideration current market conditions and nonperformance risk. We had assets of $169.4 million and $37.9 million at June 30, 2018 and December 31, 2017, respectively, related to this supply agreement. The provisional pricing arrangements included in our Level 3 assets/liabilities specify provisional price calculations, where the pricing mechanisms generally are based on market pricing, with the final revenue rate to be based on market inputs at a specified point in time in the future, per the terms of the supply agreements. The difference between the estimated final revenue rate at the date of sale and the estimated final revenue rate at the measurement date is characterized as a derivative and is required to be accounted for separately once the revenue has been recognized. The derivative instruments are adjusted to fair value through Product revenues each reporting period based upon current market data and forward-looking estimates provided by management until the final revenue rates are determined. We had assets of $5.2 million and liabilities of $3.0 million related to provisional pricing arrangements at June 30, 2018 compared to liabilities of $1.7 million related to provisional pricing arrangements at December 31, 2017. The following table illustrates information about quantitative inputs and assumptions for the assets and liabilities categorized in Level 3 of the fair value hierarchy:
The significant unobservable input used in the fair value measurement of our customer supply agreement is an estimate determined by management including a forward-looking estimate for the average annual daily market price for hot-rolled coil steel. The significant unobservable input used in the fair value measurement of our provisional pricing arrangements is management’s estimate of Platts 62% Price based upon current market data and index pricing, which include forward-looking estimates determined by management. We recognize any transfers between levels as of the beginning of the reporting period, including both transfers into and out of levels. There were no transfers between Level 1 and Level 2 and no transfers into or out of Level 3 of the fair value hierarchy during the three and six months ended June 30, 2018 and 2017. The following tables represent a reconciliation of the changes in fair value of financial instruments measured at fair value on a recurring basis using significant unobservable inputs (Level 3):
The carrying amount of certain financial instruments (e.g., Accounts receivable, net, Accounts payable and Accrued expenses) approximates fair value and, therefore, has been excluded from the table below. A summary of the carrying amount and fair value of other financial instruments were as follows:
The fair value of long-term debt was determined using quoted market prices based upon current borrowing rates. |

PENSIONS AND OTHER POSTRETIREMENT BENEFITS | NOTE 9 - PENSIONS AND OTHER POSTRETIREMENT BENEFITS We offer defined benefit pension plans, defined contribution pension plans and OPEB plans, primarily consisting of retiree healthcare benefits, to most employees in the U.S. as part of a total compensation and benefits program. The defined benefit pension plans largely are noncontributory and benefits generally are based on a minimum formula or employees’ years of service and average earnings for a defined period prior to retirement. On January 1, 2018, we adopted the amendments to ASC 715 regarding the presentation of net periodic pension and postretirement benefit costs. We retrospectively adopted the presentation of service cost separate from the other components of net periodic costs. Service costs are classified within Cost of goods sold and operating expenses, Selling, general and administrative expenses and Miscellaneous – net while the interest cost, expected return on assets, amortization of prior service costs/credits, net actuarial gain/loss, and other costs are classified within Other non-operating income in our Statements of Unaudited Condensed Consolidated Operations. The following are the components of defined benefit pension and OPEB costs and credits: Defined Benefit Pension Costs
Other Postretirement Benefits Credits
Based on funding requirements, we made pension contributions of $3.3 million and $5.6 million for the three and six months ended June 30, 2018, respectively, compared to $2.3 million of pension contributions for the three and six months ended June 30, 2017. OPEB contributions are typically made on an annual basis in the first quarter of each year, but due to plan funding requirements being met, no OPEB contributions were required or made for the three and six months ended June 30, 2018 and 2017. |

Disclosure of Compensation Related Costs, Share-based Payments [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
Stock Compensation Plans | NOTE 10 - STOCK COMPENSATION PLANS Employees’ Plans On February 21, 2018, the Compensation Committee approved grants under the A&R 2015 Equity Plan to certain officers and employees for the 2018 to 2020 performance period. Shares granted under the awards consisted of 0.7 million restricted stock units and 0.7 million performance shares. Restricted stock units granted during 2018 are subject to continued employment, are retention based and are payable in common shares. The outstanding restricted stock units that were granted in 2018 cliff vest on December 31, 2020. Performance shares are subject to continued employment, and each performance share, if earned, entitles the holder to be paid out in common shares. Performance is measured on the basis of relative TSR for the period of January 1, 2018 to December 31, 2020 and measured against the constituents of the S&P Metals and Mining ETF Index at the beginning of the relevant performance period. The final payouts for the outstanding performance period grants will vary from zero to 200% of the original grant depending on whether and to what extent the Company achieves certain objectives and performance goals as established by the Compensation Committee. Determination of Fair Value The fair value of each performance share grant is estimated on the date of grant using a Monte Carlo simulation to forecast relative TSR performance. A correlation matrix of historic and projected stock prices was developed for both the Company and our predetermined peer group of mining and metals companies. The fair value assumes that the objective will be achieved. The expected term of the grant represents the time from the grant date to the end of the service period. We estimate the volatility of our common shares and that of the peer group of mining and metals companies using daily price intervals for all companies. The risk-free interest rate is the rate at the grant date on zero-coupon government bonds with a term commensurate with the remaining life of the performance period. The following assumptions were utilized to estimate the fair value for the 2018 performance share grant:

Income Tax Disclosure [Abstract] | |
Income Taxes | NOTE 11 - INCOME TAXES Our 2018 estimated annual effective tax rate before discrete items is approximately 0.1%. The annual effective tax rate differs from the U.S. statutory rate of 21.0% primarily due to the deductions for percentage depletion in excess of cost depletion related to U.S. operations and the reversal of valuation allowance from operations in the current year. The 2017 estimated annual effective tax rate before discrete items at June 30, 2017 was negative 3.6%. For the three and six months ended June 30, 2018, we recorded discrete items that resulted in an income tax benefit of $2.0 million and an expense of $13.7 million, respectively. The $2.0 million benefit relates to the reversal of a reserve for uncertain tax positions due to a lapse in the statute of limitations. The $13.7 million expense relates primarily to a $14.5 million reduction of the refundable AMT credit recorded in Income tax receivable in our Statements of Unaudited Condensed Consolidated Financial Position based on the sequestration guidance issued by the Internal Revenue Service during the first quarter of 2018. The $14.5 million current year expense is a reduction of an asset and will not result in a cash tax outlay. For the three and six months ended June 30, 2017, we recorded discrete items that resulted in an expense of $0.3 million and $0.2 million, respectively. |

Mine Closure The accrued mine closure obligation for our active mining operations provides for contractual and legal obligations associated with the eventual closure of the mining operations. The accretion of the liability and amortization of the related asset is recognized over the estimated mine lives for each location. The following represents a roll forward of our mine closure obligation liability for the six months ended June 30, 2018 and for the year ended December 31, 2017:
For the year ended December 31, 2017, the revision in estimated cash flows relates primarily to updates to our estimates resulting from our three-year in-depth review of our mine closure obligations for each of our U.S. mines. The primary driver of the decrease in estimated cash flows was the Empire mine, as the mine closure obligation was reduced by $26.2 million as a result of the refinement of the cash flows required for reclamation, remediation and structural removal. Prior estimates were based on RS Means (a common costing methodology used in the construction and demolition industry) average costing data while the current estimate was compiled using a more detailed cost build-up approach. |

DERIVATIVE INSTRUMENTS | NOTE 15 - DERIVATIVE INSTRUMENTS The following table presents the fair value of our derivative instruments and the classification of each in the Statements of Unaudited Condensed Consolidated Financial Position:
Cash Flow Hedges Commodity Contracts As of June 30, 2018, we had outstanding natural gas hedge contracts for a notional amount of 3.4 million MMBtu in the form of forward contracts with varying maturity dates ranging from July 2018 to May 2019. As of December 31, 2017, we had outstanding natural gas hedge contracts for a notional amount of 3.5 million MMBtu in the form of forward contracts with varying maturity dates ranging from January 2018 to November 2018. Changes in fair value of highly effective hedges are recorded as a component of Accumulated other comprehensive loss in the Statements of Unaudited Condensed Consolidated Financial Position. During the three and six months ended June 30, 2018, we recorded unrealized gains of $0.2 million and $0.6 million, respectively, in Other comprehensive income (loss) for changes in the fair value of these instruments. For the six months ended June 30, 2018, a gain of $0.1 million has been reclassified from Accumulated other comprehensive loss into earnings. We had no commodity contracts designated as hedge instruments for the three and six months ended June 30, 2017. Derivatives Not Designated as Hedging Instruments Most of our long-term supply agreements are comprised of a base price with annual price adjustment factors. The base price is the primary component of the purchase price for each contract. The indexed price adjustment factors are integral to the iron ore supply contracts and vary based on the agreement, but typically include adjustments based upon changes in the Platts 62% Price, along with pellet premiums, published Platts international indexed freight rates and changes in specified Producer Price Indices, including those for industrial commodities, fuel and steel. The pricing adjustments generally operate in the same manner, with each factor typically comprising a portion of the price adjustment, although the weighting of each factor varies based upon the specific terms of each agreement. In most cases, these adjustment factors have not been finalized at the time our product is sold. In these cases, we estimate the adjustment factors at each reporting period based upon the best third-party information available. The estimates are then adjusted to actual when the information has been finalized. The price adjustment factors have been evaluated to determine if they qualify as embedded derivatives. The price adjustment factors share the same economic characteristics and risks as the host contract and are integral to the host contract as inflation adjustments; accordingly, they have not been separately valued as derivative instruments. Customer Supply Agreement A supply agreement with one customer provides for supplemental revenue or refunds to the customer based on the average annual daily steel market price for hot-rolled coil steel at the time the iron ore product is consumed in the customer’s blast furnace. The supplemental pricing is characterized as a freestanding derivative and is required to be accounted for separately once control transfers to the customer. The derivative instrument, which is finalized based on a future price, is adjusted to fair value as a revenue adjustment each reporting period until the pellets are consumed and the amounts are settled. We recognized net derivative revenue of $155.5 million and $197.4 million in Product revenues in the Statements of Unaudited Condensed Consolidated Operations for the three and six months ended June 30, 2018, respectively, related to the supplemental payments. This compares with net derivative revenue of $51.9 million and $69.6 million in Product revenues in the Statements of Unaudited Condensed Consolidated Operations for the comparable periods in 2017, related to supplemental payments. Derivative assets, representing the fair value of the supplemental revenue, were $169.4 million and $37.9 million as of June 30, 2018 and December 31, 2017 in the Statements of Unaudited Condensed Consolidated Financial Position, respectively. Provisional Pricing Arrangements Certain of our customer supply agreements specify provisional price calculations, where the pricing mechanisms generally are based on market pricing, with the final revenue rate based on certain market inputs at a specified period in time in the future, per the terms of the supply agreements. Market inputs are tied to indexed price adjustment factors that are integral to the iron ore supply contracts and vary based on the agreement. The pricing mechanisms typically include adjustments based upon changes in the Platts 62% Price, along with pellet premiums, published Platts international indexed freight rates and changes in specified Producer Price Indices, including those for industrial commodities, fuel and steel. The pricing adjustments generally operate in the same manner, with each factor typically comprising a portion of the price adjustment, although the weighting of each factor varies based upon the specific terms of each agreement. Revenue is recognized generally when iron ore is delivered to our customers. Revenue is measured at the point that control transfers and represents the amount of consideration we expect to receive in exchange for transferring goods. Changes in the expected revenue rate from the date that control transfers through final settlement of contract terms is recorded in accordance with ASC Topic 815 and is characterized as a derivative and accounted for separately. Subsequently, the derivative instruments are adjusted to fair value through Product revenues each reporting period based upon current market data and forward-looking estimates provided by management until the final revenue rate is determined. At June 30, 2018, we recorded $5.2 million as Derivative assets and $3.0 million as derivative liabilities classified as Other current liabilities related to our estimate of the final revenue rate with our customers in the Statements of Unaudited Condensed Consolidated Financial Position. At December 31, 2017, we recorded $1.7 million as derivative liabilities classified as Other current liabilities related to our estimate of the final revenue rate with our customers in the Statements of Unaudited Condensed Consolidated Financial Position. These amounts represent the difference between the amount we expected to receive when revenue was initially measured at the point control transfers and our subsequent estimate of the final revenue rate based on the price calculations established in the supply agreements. We recognized a net decrease of $0.8 million and increase of $1.1 million in Product revenues in the Statements of Unaudited Condensed Consolidated Operations for the three and six months ended June 30, 2018, respectively, related to these arrangements as compared to a net decrease of $21.1 million and $5.3 million in Product revenues for the comparable periods in 2017. The following summarizes the effect of our derivatives that are not designated as hedging instruments in the Statements of Unaudited Condensed Consolidated Operations:

DISCONTINUED OPERATIONS | NOTE 16 - DISCONTINUED OPERATIONS The information below sets forth selected financial information related to operating results of our businesses classified as discontinued operations. While the reclassification of revenues and expenses related to discontinued operations from prior periods have no impact upon previously reported net income, the Statements of Unaudited Condensed Consolidated Operations present the revenues and expenses that were reclassified from the specified line items to discontinued operations and the Statements of Unaudited Condensed Consolidated Financial Position present the assets and liabilities that were reclassified from the specified line items to assets and liabilities of discontinued operations. The information below sets forth selected financial information related to operating results of our businesses classified as discontinued operations which include our former Asia Pacific Iron Ore, North American Coal and Canadian operations. The charts below provide an asset group breakout for each financial statement line impacted by discontinued operations.
For the six months ended June 30, 2018, we had $28.6 million of non-cash financing activities related to the settlement of capital lease obligations at Asia Pacific Iron Ore. Asia Pacific Iron Ore Operations Background In January 2018, we announced that we would accelerate the time frame for the planned closure of our Asia Pacific Iron Ore mining operations in Australia. In April 2018, we committed to a course of action leading to the permanent closure of the Asia Pacific Iron Ore mining operations and, as planned, completed our final shipment in June 2018. Factors considered in this decision included increasingly discounted prices for lower-iron-content ore and the quality of the remaining iron ore reserves. During June 2018, we completed a sale of the mobile equipment to a third party and entered into a definitive agreement to sell substantially all of the remaining assets of our Asia Pacific Iron Ore business to Mineral Resources Limited. The sale to Mineral Resources Limited has not been completed as of the date of this report due to the pendency of certain closing conditions. As a result, for the period ended June 30, 2018, management determined that our Asia Pacific Iron Ore operating segment met the criteria to be classified as held for sale and a discontinued operation under ASC 205, Presentation of Financial Statements. As such, all current and historical Asia Pacific Iron Ore operating segment results are included in our financial statements and classified within discontinued operations. Loss on Discontinued Operations For the reasons discussed above, our previously reported Asia Pacific Iron Ore operating segment results for all periods prior to June 30, 2018, as well as exit costs, are classified as discontinued operations.
Recorded Assets and Liabilities
Foreign Currency The functional currency of our Australian subsidiaries is the Australian dollar. The financial statements of our Australian subsidiaries are translated into U.S. dollars using the exchange rate at each balance sheet date for assets and liabilities and a weighted average exchange rate for each period for revenues, expenses, gains and losses. Translation adjustments are recorded as Accumulated other comprehensive loss. Income taxes generally are not provided for foreign currency translation adjustments. Upon the liquidation of substantially all of the Asia Pacific Iron Ore assets, which is expected to occur during the third quarter 2018, the historical cumulative translation adjustments recorded in Accumulated other comprehensive loss in the Statements of Unaudited Condensed Consolidated Financial Position related to that asset group will be recognized as a gain in the Statements of Unaudited Condensed Consolidated Operations. As of June 30, 2018, the balance of currency translation adjustments related to the Asia Pacific Iron Ore asset group in Accumulated other comprehensive loss was a gain of $228.3 million. Income Taxes We have not recognized a tax benefit or expense during the three and six months ended June 30, 2018, related to our Asia Pacific Iron Ore operations. For the three and six months ended June 30, 2017, we recognized a tax expense of $3.7 million and $0.8 million, respectively. Eastern Canada Iron Ore Operations Effective January 27, 2015, following the commencement of CCAA proceedings for the Bloom Lake Group, we deconsolidated the Bloom Lake Group and certain other wholly-owned subsidiaries comprising substantially all of our Canadian operations. Additionally, on May 20, 2015, the Wabush Group commenced CCAA proceedings which resulted in the deconsolidation of the remaining Wabush Group entities that were not previously deconsolidated. As a result of this action, the CCAA protection granted to the Bloom Lake Group was extended to include the Wabush Group to facilitate the reorganization of each of their businesses and operations. Prior to the deconsolidations, certain of our wholly-owned subsidiaries made loans to the Canadian Entities for the purpose of funding their operations and had accounts receivable generated in the ordinary course of business. The loans, corresponding interest and the accounts receivable were considered intercompany transactions and eliminated in our consolidated financial statements. Since the deconsolidations, the loans, associated interest and accounts receivable are considered related party transactions and have been recognized in our consolidated financial statements at their estimated fair value. As of June 30, 2018, we had no amounts outstanding classified as Loans to and accounts receivable from the Canadian Entities in the Statements of Unaudited Condensed Consolidated Financial Position in accordance with the Amended Plan, as defined and described below. As of December 31, 2017, we had $51.6 million classified as Loans to and accounts receivable from the Canadian Entities in the Statements of Unaudited Condensed Consolidated Financial Position. The net proceeds from the sale of the assets of the Bloom Lake Group and the Wabush Group are currently being held by the Monitor. Certain of these proceeds will be utilized to fund the accrued and remaining costs of the CCAA proceedings, and the remaining amounts will be available for distribution to the creditors of the Bloom Lake Group and the Wabush Group in accordance with the Amended Plan (as defined below). During 2017, we became aware that it was probable the Monitor will assert a preference claim against us and/or certain of our affiliates. We estimated a liability, which included the value of our related-party claims against the Bloom Lake Group and the Wabush Group, classified as Contingent claims in the Statements of Unaudited Condensed Consolidated Financial Position. As described below, as of June 30, 2018, the estimated liability has been settled pursuant to the Amended Plan. During March 2018, we entered into a restructuring term sheet with the Bloom Lake Group and the Wabush Group, which documents the proposed terms of a plan of compromise or arrangement in the CCAA proceedings to be sponsored by us as negotiated between us and the Monitor. By order of the Québec Superior Court of Justice (Commercial Division) (the “Court”) dated April 20, 2018, the Bloom Lake Group and the Wabush Group were authorized to file a joint plan of compromise and arrangement dated April 16, 2018 (the “Original Plan”). Following discussions with various stakeholder groups, the Original Plan was amended by order of the Court dated May 18, 2018. The Bloom Lake Group and the Wabush Group were authorized to file the amended and restated joint plan of compromise and arrangement dated May 16, 2018 (as same may be further amended from time to time, the “Amended Plan”). The Amended Plan was approved by the required majorities of each unsecured creditor class and was sanctioned by the Court by order dated June 29, 2018 (the “Sanction Order”). In addition, the Bloom Lake Group and the Wabush Group will bring a motion before the Court on July 30, 2018 seeking to make further amendments to the Amended Plan to address the manner in which certain distributions under the Amended Plan will be effected. There are certain conditions precedent to the implementation of the Amended Plan that must be satisfied on or before July 31, 2018, subject to any extension of such date as agreed between the Monitor, the Bloom Lake Group, the Wabush Group and us. Subject to the proposed amendments to the Amended Plan described above and the finalization of certain required arrangements with applicable taxing authorities, the conditions precedent under the Amended Plan are expected to be satisfied by July 31, 2018. Under the terms of the Amended Plan, we and certain of our wholly-owned subsidiaries have made a C$19.0 million cash contribution to the Wabush Group pension plans and will contribute into the CCAA estate any distributions or payments we may be entitled to receive as creditors of the Bloom Lake Group and the Wabush Group for distribution to other creditors. The Original Plan did not resolve certain employee claims asserted against us and certain of our affiliates outside of the CCAA proceedings. The Amended Plan resolves those employee claims, all claims by the Bloom Lake Group, the Wabush Group and their respective creditors against us as well as all of our claims against the Bloom Lake Group and the Wabush Group. The net financial impact of the Amended Plan has been recorded in our financial statements. |

The following table presents the classification of related party assets and liabilities in the Statements of Unaudited Condensed Consolidated Financial Position:
During 2017, our ownership interest in Empire increased to 100% as we reached an agreement to distribute the noncontrolling interest net assets of $132.7 million to ArcelorMittal, in exchange for its interest in Empire. The net assets were agreed to be distributed in three installments of $44.2 million each, the first of which was paid upon the execution of the agreement and the remaining two of which are due in August 2018 and August 2019. The remaining two outstanding installments are reflected in Partnership distribution payable and Other liabilities in the Statements of Unaudited Condensed Consolidated Financial Position as of June 30, 2018. A supply agreement with a customer provides for supplemental revenue or refunds to the customer based on the average annual daily market price for hot-rolled coil steel at the time the product is consumed in the customer’s blast furnace. The supplemental pricing is characterized as a freestanding derivative. Refer to NOTE 15 - DERIVATIVE INSTRUMENTS for further information. |

Commitments and Contingencies Disclosure [Abstract] | |
COMMITMENTS AND CONTINGENCIES | NOTE 20 - COMMITMENTS AND CONTINGENCIES Contingencies We are currently the subject of, or party to, various claims and legal proceedings incidental to our operations. If management believes that a loss arising from these matters is probable and can reasonably be estimated, we record the amount of the loss or the minimum estimated liability when the loss is estimated using a range, and no point within the range is more probable than another. As additional information becomes available, any potential liability related to these matters is assessed and the estimates are revised, if necessary. Based on currently available information, management believes that the ultimate outcome of these matters, individually and in the aggregate, will not have a material effect on our financial position, results of operations or cash flows. However, these claims and legal proceedings are subject to inherent uncertainties and unfavorable rulings could occur. An unfavorable ruling could include monetary damages, additional funding requirements or an injunction. If an unfavorable ruling were to occur, there exists the possibility of a material impact on the financial position and results of operations for the period in which the ruling occurs or future periods. However, we do not believe that any pending claims or legal proceedings will result in a material liability in relation to our consolidated financial statements. Currently, we have recorded a liability in the Statements of Unaudited Condensed Consolidated Financial Position related to the following legal matter: Michigan Electricity Matters. On February 19, 2015, in connection with various proceedings before FERC with respect to certain cost allocations for continued operation of the Presque Isle Power Plant in Marquette, Michigan, FERC issued an order directing MISO to submit a revised methodology for allocating SSR costs that identified the load serving entities that require the operation of SSR units at the power plant for reliability purposes. On September 17, 2015, FERC issued an order conditionally approving MISO’s revised allocation methodology. On September 22, 2016, FERC denied requests for rehearing of the February 19 order, rejecting arguments that FERC did not have the authority to order refunds in a cost allocation case and to impose retroactive surcharges to effectuate such refunds. FERC, however, suspended any refunds and surcharges pending its review of a July 25, 2016 ALJ initial decision on the appropriate amount of SSR compensation. This suspension was ultimately lifted after FERC’s Order on Initial Decision of October 19, 2017, affirming in part and reversing in part certain aspects of the ALJ’s decision, and FERC’s order on February 28, 2018, directing that refunds and surcharges be effectuated over a ten-month period beginning on the date of the order. Our current estimate of the potential liability to the Empire and Tilden mines is $13.0 million in the aggregate, based on a schedule of anticipated surcharges (including interest) for the Escanaba, White Pine and Presque Isle SSRs from Empire and Tilden's electricity supplier. During the six months ended June 30, 2018, Tilden and Empire made payments on invoiced surcharges totaling $2.2 million. Separate from these SSR compensation issues, Tilden and Empire, along with various Michigan-aligned parties, had filed petitions for review regarding allocation and non-cost SSR issues with the U.S. Court of Appeals for the D.C. Circuit. Oral arguments on those issues were completed on April 6, 2018. We will continue to vigorously challenge the imposition of any retroactive SSR costs before the U.S. Court of Appeals for the D.C. Circuit. As of June 30, 2018, $10.8 million is included in our Statements of Unaudited Condensed Consolidated Financial Position as part of Accrued expenses for the remaining portion of this estimated liability. Additionally, we previously recorded a liability in the Statements of Unaudited Condensed Consolidated Financial Position related to the following matter, in which a settlement was reached during the period ended June 30, 2018: CCAA Proceedings Effective January 27, 2015, following the commencement of CCAA proceedings for the Bloom Lake Group, we deconsolidated the Bloom Lake Group and certain other wholly-owned subsidiaries comprising substantially all of our Canadian operations. Additionally, on May 20, 2015, the Wabush Group commenced CCAA proceedings which resulted in the deconsolidation of the remaining Wabush Group entities that were not previously deconsolidated.
