Sponge iron, Sulphur content : 2%

Reduced iron derives its name from the chemical change that iron ore undergoes when it is heated in a furnace at high temperatures in the presence of hydrocarbon-rich gases, carbon monoxide, or elemental carbon. Direct reduction refers to processes which reduce iron oxides to metallic iron at temperatures below the melting point of iron. The product of such solid state processes is called direct reduced iron. In the Direct Reduced Iron (DRI) plant, production of sponge iron is done using coal. This reduction process is done in a rotary kiln at temperature of around
