Question

describe the role of SiO2 in the extraction of copper matte​

Answer 1

Answer:

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).

Answer 2

Answer:

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).

CuFeS2 + heat ---> Cu2s + FeS + SO2

FeS + O2 ----> Feo

FeO + SiO2 ----> FeSiO3
