ArcelorMittal USA operates an iron ore mine through its wholly-owned subsidiary ArcelorMittal Minorca and owns a majority stake in Hibbing Taconite Company, which is managed by Cliffs Natural Resources.
On December 9, 2020, ArcelorMittal announced the sale of ArcelorMittal USA to Cleveland-Cliffs.
Summary:
Both the Minorca and Hibbing mines are located in the Mesabi iron range where iron ore has been extracted for over 100 years. The ore bodies are within the Biwabik Iron Formation, a series of shallow dipping Precambrian sedimentary rocks known as taconite with a total thickness in excess of 200 meters and running for approximately 200 kilometers. Although the first deposits mined in the Mesabi iron range consisted of oxidized hematite ores, production was shortened in the mid-1950 to low grade magnetic taconite ores
Processing
