equation for reduction of iron ore

  • THE FUNDAMENTAL ASPECTS OF IRON ORE REDUCTION

    T RON ore reduction is the conversion of iron oxide minerals to metallic iron. The chemical reactions involved take place in the blast furnace during the production of hot metal or in the several proposed solid-state processes that pro-duce sponge iron. Because there are three oxides of iron hematite magnetite and wustite and be-

  • Iron Ore Reductionan overview ScienceDirect Topics

    The research on the reduction of iron ore has received much attention in the past few decades as a result of the increasing cost and low availability of raw materials. The reduction of gaseous emissions and the search for low-cost alternatives to traditional routes has also boosted the investigations for reduction processes ( Plaul et al. 2009 ).
