  • Corex Process

    In addition, the Corex process can use iron oxides containing up to 80% lump ore and uses non coking coal directly as a reducing agent. In the Reduction shaft the iron ore, along with limestone and dolomite additives, is added and then reduced by reduction gas into 95% direct reduced iron, DRI.

  • Bessemer process

    The Bessemer process was the first inexpensive industrial process for the mass production of steel from molten pig iron before the development of the open hearth furnace.The key principle is removal of impurities from the iron by oxidation with air being blown through the molten iron. The oxidation also raises the temperature of the iron mass and keeps it molten.

  • Hydrogen production by steamiron process ScienceDirect

    The process operates two stages during the reduction step the iron ores are reduced by synthesis or biomass gas, which is thereby oxidised to a lean gas with low remaining CO (68%) and H 2 (ca. 6%) content. In the subsequent oxidation step, the iron ore is re oxidised by water vapour yielding an hydrogen rich fuel gas.

  • Extraction Process of Aluminium from Bauxite Ore

    It is essential that the Al2O3 (alumina) be obtained substantially free from these impurities as otherwise the iron oxide and silica would be reduced and contaminate the metallic aluminum produced in the Hall (or Heroult) Process. The separation of the alumina from the impurities in the bauxite ore is usually accomplished by the Bayer Process.

  • 1A Manufacturing Process for Iron and Steel

    The smelting and refining process for iron and steel in the BF BOF process involves the carbon reduction of iron ore (Fe 2 O 3) in the BF to make molten iron, and decarburization of molten iron in the BOF to make molten steel. Major reducing agent in the BF is the carbon monoxide gas(CO) generated by the oxidation of the carbon(C) in coke.
