Extraction of zinc from zinc blende is achieved by

Options

  1. Aroasting followed by reduction with another metal
  2. Belectrolytic reduction
  3. Croasting followed by reduction with carbon
  4. Droasting followed by self-reduction

Correct answer

C. roasting followed by reduction with carbon

Step-by-step solution

Extraction of Zinc from Zinc blende is achieved by roasting followed by reduction with carbon as follows Z n S + 3 2 O 2 → Δ Z n O + S O 2 Z n S + 2 O 2 → Δ Z n S O 4 → Δ Z n O + S O 2 + 1 2 O 2 Z n O + C → Δ Z n + C O
