The chemical composition of ‘slag’ formed during the smelting process in the extraction of copper is

A.Cu₂O + FeS

B.FeSiO₃✓ Correct

C.CuFeS₂

D.Cu₂S + FeO

Explanation

The copper is extracted from cuprous oxide or copper (I) oxide. So, in this process, there is the formation of slag. The formula of slag is 3 FeSiO . This is formed by silica and ferrous oxide. The reaction is given below: 2 3 FeO+SiO FeSiO →
