In the extraction process of copper, the product obtained after carrying out the reactions (i) 2 Cu 2 S + 3 O 2 ⟶ 2 Cu 2 O + 2 SO 2 (ii) 2 Cu 2 O + Cu 2 S ⟶ 6 Cu + SO 2 is called

Options

  1. ABlister copper
  2. BReduced copper
  3. CCopper scrap
  4. DCopper matte

Correct answer

A. Blister copper

Step-by-step solution

The copper(I) sulphide produced is converted to copper with a final blast of air. The end product of this is called blister copper - a porous brittle form of copper, about 98   -   99 . 5 % pure. The reactions given are carried out in the production of blister copper using self reduction.
