Which of the following mixtures is called matte?

A.CuO + Cu₂S
B.PbS + PbSO₄✓ Correct
C.Cu₂S + FeO
D.Cu₂S + FeS
Explanation

In the extraction of copper from cuprous oxide or copper (I) oxide there is the formation a molten layer is formed. This layer is known as copper matte. This layer is made up of two components, i.e., Cu₂S and FeS, So, the mixture of Cu₂S and FeS is a matte. 57. The extraction of which of the following metals involves bessemerisation? (a) Fe (b) Ag (c) Al (d) Cu By the process of bessemerization, copper is formed. In the Bessemer converter, copper sulphides are oxidised to form 2 Cu O and FeO where FeO is removed as slag and 2 Cu O reacts with 2 Cu S and forms copper. Therefore, the correct
