Identify the reaction that doesn't take place during the smelting process of copper extraction

Options

  1. A2 FeS +3 O ₂ 2 FeO +2 SO ₂
  2. BCu ₂ O + FeS Cu ₂ ~S + FeO
  3. C2 Cu ₂ ~S +3 O ₂ 2 Cu ₂ O +2 SO ₂
  4. DFeO + SiO ₂ FeSiO ₃

Correct answer

A. 2 FeS +3 O ₂ 2 FeO +2 SO ₂

Step-by-step solution

The reaction that doesn't take place during the smelting process of extraction is 2 FeS +3 O ₂ 2 FeO +2 SO ₂ This reaction occurs during roasting, which comes before smelting.
