The final step for the extraction of copper from copper pyrite in Bessemer converter involves the reaction-

Options

  1. A4 C u 2 O + F e S → 8 C u + F e S O 4
  2. BC u 2 S + 2 C u 2 O → 6 C u + S O 2
  3. C2 Cu 2 O + FeS → 4 Cu + Fe + SO 2
  4. DC u 2 S + 2 F e O → 2 C u + 2 F e C O + S O 2

Correct answer

B. C u 2 S + 2 C u 2 O → 6 C u + S O 2

Step-by-step solution

In Bessemer converter copper sulphide is partially oxidised to cuprous oxide which further reacts with remaining copper sulphide to form copper and sulphur dioxide. C u 2 S + 2 C u 2 O → 6 C u + S O 2
