How Is Iron Extracted From the Earth?

Mar 26, 2020· 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.Iron ore mining and dressing - tec-science,Jan 01, 2015· Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used.
