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 →
