  • Iron ore Wikipedia

    Iron ore being unloaded at docks in Toledo, Ohio Iron ores are rocks and minerals from which metallic iron can be economically extracted The ores are usually rich in iron oxides and vary in color from dark grey, bright yellow, or deep purple to rusty red The iron is usually found in the form of magnetite (Fe 3 O 4, 724% Fe), hematite (Fe 2 O 3, 699% Fe), goethite (FeO(OH), 629% Fe· Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities The iron ore is dressed or crushed into 051 in chunks, which increases surface area for reactions Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed ore Roasting or calcination of the ore oxidizes some of theIronmaking 101 – From Ore to Iron with Blast Furnaces
