THE FUNDAMENTAL ASPECTS OF IRON ORE

iron ore reduction processes must not be overlooked and a satisfactory solution must be found. IRON OXIDES Iron has three oxides, ferric oxide or hematite (Fe203), magnetite (Fes(%) and ferrous oxide or wustite Fe,O, where x has a value that can vary between about 0.85 and 0.9'5). Both hematite and magnetite exist in nature and are the

Direct Reduction of Iron A Review on Midrex and Hyl Patents

Ironmaking is the major energy consuming and CO2emmiting step in steel production. Direct reduction processes are an alternative to the traditional blast furnace because of the use of H2 in the reducing gases which generate less CO2. There are two main technologies for direct reduction of iron, Midrex and Energiron (or Hyl) which together are responsible for 80% of

Direct reduced iron

Direct reduced iron, also called sponge iron, is produced from the direct reduction of iron ore into iron by a reducing gas or elemental carbon produced from natural gas or coal. Many ores are suitable for direct reduction. Direct reduction refers to solidstate processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these
