The iron ore is predominantly mined by opencast mining throughout the country. The solid material generated in large quantities by iron ore extraction is the material that overlies the ore body and the processed tailings . These wastes contain minerals associated with the ore body and host rock, mainly the laterite, and sometimes the clays.

The first step in the steel manufacture begins at the blast furnace. To separate iron from iron ore coke (substance when gas is taken out of coal), limestone and dolomite are charged into the blast furnace. Temperature raised to 1600oF. This high temp causes the coke to burn and melt the iron. This red hot iron drained at an opening at the base of the furnace.
