    During the roasting of pyrite ore, a mixture of FeO and Cu 2 O is obtained. The role of silica in the metallurgy of copper is to remove the iron oxide obtained during the process of roasting as 'slag'. If the sulphide ore of copper contains iron, then silica SiO 2 is added as flux before roasting.
