  • How Is Iron Extracted From the Earth?

     · 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.

  • How iron is made

    The ingredients to make useable iron were limestone, ironstone, coke and air. The coke is the fuel and the ironstone provides the iron ore. Ironstone is first roasted in calcining kilns, located next to the blast furnaces, to remove impurities. The air, or blast, was blown into …

  • Iron Ore Mining | Techniques | Metal Extraction

    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.
