WEBSponge Iron Production. Sponge iron is produced through the careful blending of nearly equal proportions of the necessary grades of iron ore and noncoking coal. An essential component in this process is % dolomite. The inclusion of % dolomite is critical for regulating and mitigating the presence of sulphides in the final product.
WEBAug 7, 2016 · Coal plays a dual role in the Kiln. Part of coal is used as fuel to supply the desired heat so as to take the raw materials to the desired temp. But main role of coal is to supply carbon in the reduction process. Dolomite is used as sulphur scavenger which finally comes out with the char. Char contains ash of coal and other impurities of iron ore.
