In the extraction of copper from its sulphide ore, the metal is formed by the reduction of Cu ₂ O with

Options

  1. AFeS
  2. BCO
  3. CCu ₂ ~S
  4. DSO ₂

Correct answer

C. Cu ₂ ~S

Step-by-step solution

In the extraction of copper from its sulphide ore, the metal is formed by the reduction of Cu ₂ O with Cu ₂ ~S . This reaction completes with the process of auto-reduction. Chemical reaction occuring in this reaction is as follows aligned & 2 Cu ₂ ~S +3 O ₂ 2 Cu ₂ O +2 SO ₂ & Cu ₂ O + 1 2 Cu ₂ ~S 3 Cu + 1 2 SO ₂ aligned The molten copper is allowed to cool. During cooling, dissolved SO ₂ comes out in the form of blisters, soit is called blister copper.
