The extraction of iron from its ore is the third and the penultimate process in metallurgy, which is the process of separating metals from their ores. The common ores of iron are iron oxides. These oxides can be reduced to iron by heating them with carbon in the form of coke. Heating coal in the absence of air produces coke.

Verified by Toppr. During the roasting of pyrite ore, a mixture of F eO and Cu2O is obtained. The role of silica in the metallurgy of copper is to remove the iron oxide obtained during the process of extraction of pure copper from copper pyrite, SiO2 acts as acidic flux which combines with iron oxide ( F eO) to form iron silicate ( F eSiO3 ).
