Q75 / 180 · NEET 2015 (Phase 2) · Chemistry

In the extraction of copper from its sulphide ore, the metal is finally obtained by the reduction of cuprous oxide with:

A
Iron (II) sulphide
B
Carbon monoxide
Correct answer
C
Copper (I) sulphide
D
Sulphur dioxide

Solution

One of the process in extraction of copper is self-reduction of the ore after roasting.

C u_{2} S + 2 C u_{2} O ⟶ 6 C u + S O_{2} ↑

Hence, the correct answer is option: 'C'.
