crushing process of iron ores

  • Iron ore Wikipedia

    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), limonite (FeO(OH)·n(H 2 O), 55% Fe) orA crusher is a machine designed to reduce large rocks into smaller rocks, gravel, sand or rock dust Crushers may be used to reduce the size, or change the form, of waste materials so they can be more easily disposed of or recycled, or to reduce the size of a solid mix of raw materials (as in rock ore), so that pieces of different composition can be differentiatedCrusher Wikipedia
