The main sources of sponge iron are iron ore and non-coking coal. These are put into a rotary kiln in the required ratio along with some dolomite used for desulfurization. The coal plays a dual role in the process, acting as a reductant and as a fuel that provides heat to maintain the required temperature in the kiln between 850-1100°C.
