    Iron Ore Statistics and InformationUSGS

    2 days ago · Iron Ore Statistics and Information. Iron ore is a mineral substance which when heated in the presence of a reductant will yield metallic iron (Fe). It almost always consists of iron oxides the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world s iron and steel

  • Iron Ore Geoscience Australia

     · Iron Ore. Iron (Fe) is a metallic element which constitutes about 5 of the Earth s crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores are hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Almost all iron ore is used in blast furnaces to

     · Iron is concentrated by the process of calcinations. Once it is concentrated the water and other volatile impurities such as sulfur and carbonates are removed. This concentrated ore is then mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top. It is in the blast furnace that extraction of iron occurs.
