Question

Cu₂S + 2Cu₂O⟶6Cu + SO₂
In which process of metallurgy of copper, above
equation is involved?
(a) Roasting (b) Self reduction
(c) Refining (d) Purification

Answer 1

Answer:

Self reduction is the correct answer.

Answer 2

(b) Self reduction

Explanation:

During Bessemerisation of copper, the reaction taking place in the Bessemer converter is: 2Cu₂S+ 3O₂ ---> 2Cu₂O + 2SO₂

Copper sulphide gets auto reduced in the Bessemer converter. Copper sulphide is partially oxidised to cuprous oxide which futher can react with remaining copper sulphide to form copper and sulphur dioxide.

Option B is the answer.
