How Is Iron Extracted From the Earth? - Reference

Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

Only those parts of the iron formation where some natural process had concentrated the iron ore to at least 50% of the total rock to be removed could be mined at a profit. About 6% of the iron-formation area met this requirement. These rich, natural concentrates, called direct-shipping ores, were considered the only profitable ores until the 1950s.
