In the extraction of C u , the metal is formed in the Bessemer converter due to the reaction:

Options

  1. ACu 2 S + 2 Cu 2 O → Δ 6 Cu + SO 2
  2. BCu 2 S → 2   Cu + S
  3. CFe + Cu 2 O → 2   Cu + FeO
  4. D2   Cu 2 O → 4   Cu + O 2

Correct answer

A. Cu 2 S + 2 Cu 2 O → Δ 6 Cu + SO 2

Step-by-step solution

The following reaction taken place in the formation of blister copper in the Bessemer converter Cu 2 S   +   2   Cu 2 O   → Δ   6   Cu   +   SO 2
