  • Raw materials Iron and steelmaking I: Ironmaking

    There are several iron ore mines in the world, so we get the iron ore to produce iron. The iron ore is basically iron oxide but this is not a pure chemical it contains certain levels of impurities and through the iron making process the oxygen from iron ore must be taken out. This is done by carbon. Carbon is contained in coke. Coke is also

  • Iron processing The metal Britannica

    2020-8-14 · Iron processing Iron processing The metal: Most blast furnaces are linked to a basic oxygen steel plant, for which the hot metal typically contains 4 to 4.5 percent carbon, 0.6 to 0.8 percent silicon, 0.03 percent sulfur, 0.7 to 0.8 percent manganese,

    2011-1-6 · The process reduces iron ore using a reforming gas made from natural gas. The DRI is used mainly as the raw material for electric arc furnaces (EAFs), as a clean iron source substitute for scrap iron. Pores are left behind in the DRI after oxygen has been removed. These pores, if filled with water, for example, can cause the iron to reoxidize with

    2021-2-21 · The process used in converting raw metals like iron ore into steel involves beneficiation, or crushing and separation, and smelting, the process of heating the ore to obtain the pure metal. Processing of raw materials like trees may involve an entirely different process

  • Iron Ore Sinter an overview ScienceDirect Topics

    L. Lu, O. Ishiyama, in Iron Ore, 2015. 14.5 Conclusions. Sintering is the most economic and widely used agglomeration process to prepare iron ore fines for blast furnace use. Compared with pellets, production of sinter is cheaper, and compared with lump ore, fluxed sinter is often more reducible with better softening characteristics.
