  • Direct reduced iron Wikipedia

    Direct reduced iron (DRI), also called sponge iron, is produced from the direct reduction of iron ore (in the form of lumps, pellets, or fines) to 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 solid-state processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. Reduced iron derives its name from these processes, one example beinrotary kiln iron ore caseconnectionzone,Boudouard reaction, dolomite, DRI, Iron ore, metallization, non coking coal, pellets, reduction, Rotary kiln, Sponge iron, Sulphur, Coal based Direct Reduction Rotary Kiln Process .
