Answer:

In the extraction of copper from copper matte, SiO2 reacts with iron oxide to form slag of ferrous silicate and is removed.

FeO+SiO2----- fesio3.

It acts as flux to removiron oxide as silicate (slag). FeO + SiO2 → FeSiO3 (Slag)

During the process of extraction of pure copper from copper pyrite,SiO2 acts as acidic flux which combines with iron oxide(FeO) to form iron silicate(FeSiO3).
