Question

2CuFeS₂ + O₂ ⟶ Cu₂S + 2FeS + SO₂
Which process of metallurgy of copper is
represented by above equation?
(a) Concentration (b) Roasting
(c) Reduction (d) Purification

Answer 1

Answer:

(b) Roasting is the correct answer

Answer 2

(b) Roasting

Explanation:

2CuFeS₂ + O₂ ---> Cu₂S + 2FeS + SO₂

The process of metallurgy of copper represented by the above equation is roasting. Copper is extracted from its principal ore copper pyrites (CuFeS2). The ore is concentrated by froth flotation process. The concentrated ore is roasted in a reverberatory furnace when the above reaction occurs.

Option B is the answer
