Direct reduced iron

Direct reduced iron

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) 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
