Iron mining in the United States
Minnesota provides the great bulk of the iron ore mined in the US. Iron ore comes from seven open-pit mines, and two tailings reclamation operations, one in St. Louis County, and one in Itasca County. Three of the mines are operated by Cleveland Cliffs, two by U.S. Steel, and one each by Mesabi Nugget Delaware LLC and Arcelor Mittal S.A. The two reclamation projects are operated by Magnetation, Inc.

Existing and New Processes for Beneficiation of
The iron ore industries of India are expected to bring new technologies to cater to the need of the tremendous increase in demand for quality ores for steel making. With the high-grade ores depleting very As the only major steel maker not harmed during World War II, the United States iron and steel industry reached its maximum world importance during and just after World War II. In 1945, the US produced 67% of the world's pig iron, and 72% of the steel. By comparison, 2014 percentages were 2.4% of the pig iron, and 5.3% of the steel production.History of the iron and steel industry in the United States

Biobeneficiation of bauxite using Bacillus polymyxa: calcium and iron
Calcium and iron removal from a bauxite ore by Bacillus polymyxa has been demonstrated. Within a period of 7 days, the above organism could remove all the calcium and about 45% of iron from the ore in the presence of 2% sucrose in a Bromfield medium. The highest removal of calcium and iron corresponded with the maximum in Research regarding iron ore flotation began in 1931, demonstrating that reverse cationic flotation is a very efficient method for beneficiating oxidised iron ores.
