The primary raw materials for sponge iron are iron ore and non-coking coal. These are charged into a rotary kiln in the required ratio, along with dolomite, which acts as a desulphurizer. The kiln is heated to 850-1100 deg C for the reduction process to take place. The resulting product is a sponge-like micropic view of Fe2O3.
