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

Options

  1. AIron (II) sulphide
  2. BCarbon monoxide
  3. CCopper (I) sulphide
  4. DSulphur dioxide

Correct answer

C. Copper (I) sulphide

Step-by-step 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 ↑
