Which set of chemical reactions correctly represents the extraction of zinc from zinc blende (ZnS)?

Options

  1. AZnS + 2O 2 → 2ZnO + 2SO 2 ZnO + C → Zn + CO
  2. BZnS + 3O 2 → ZnSO 4 ZnSO 4 → ZnO + SO 2
  3. CZnS + 2O 2 → 2ZnO + 2SO 2 2ZnO + C → 2Zn + CO 2
  4. DZnS + 3O 2 → ZnSO 4 ZnSO 4 → ZnO + SO 3

Correct answer

C. ZnS + 2O 2 → 2ZnO + 2SO 2 2ZnO + C → 2Zn + CO 2

Step-by-step solution

Correct Option is : (C) ZnS + 2O 2 → 2ZnO + 2SO 2 2ZnO + C → 2Zn + CO 2
