It has been found out that around 1.6-1.75 tonne of Fe, 1.2- 1.5 tonne of coal amp 0.035 tonne of dolomite are required for production of one tonne of sponge iron. This results in production of 0.54 tonne of solid waste which includes 0.25 tonne of dust and 0.29 tonne of coal char. Due to non- availability of good grade of coal, the amount of char fines increases.
