  • Iron Ore Reduction by Hydrogen Using a Laboratory Scale

    2019/07/24· During the direct reduction of iron oxide with hydrogen at temperatures above 843 K, the reduction proceeds from hematite Fe2O3viamagnetite Fe3O4to wüstite FeO and finally to metallic iron Fe. Below 843 K, reduction occurs from magnetite directly to metallic iron, owing to wüstite not being stable below 843 K. The reactions are shown in Eqs.

The product is liquid pig iron, which can be treated and refined in the same way as hot metal from the BF. So far, only the COREX® process has been commercially proved, but a number of other variants are in an advanced stage of development.

  • Iron ore Wikipedia

    Iron ores[1] 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 3O 4, 72.4% Fe), hematite (Fe 2O 3, 69.9% Fe), goethite (FeO(OH), 62.9% Fe
