Crushing. As-mined iron ore contains lumps of varying size, the biggest being than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size. Crushed ore is divided into various fractions.

Conducting complete energy audit (both process and utility) of a sponge iron unit is challenging as there is no laid down procedure to audit the process side. Further, the average heat to power ratio (kW th kW e ) of sponge iron plants ranges from (25 1) to (31 1). This shows that the manufacturing process mostly uses thermal energy and application of electrical energy is insignificant.
