The chemical composition of slag formed during the smelting process in the extraction of copper is

Options

  1. ACu 2 O   +   FeS
  2. BFeSiO 3
  3. CCuFeS 2
  4. DCu 2 S   +   FeO

Correct answer

B. FeSiO 3

Step-by-step solution

In the smelting process of copper from copper pyrites the following reactions takes place Cu 2 O   +   FeS → Cu 2 S   +   FeO 2FeS   +   3O 2 → 2FeO   +   2SO 2
