Question

The process of extracting crude metal from its oxide by heating with a reducing agent (like C or CO) is called:
  1. A
    Smelting
    Correct
  2. B
    Roasting
  3. C
    Calcination
  4. D
    Leaching

Correct answer

Smelting

Explanation

Smelting: ore oxide + reducing agent (C or CO) → metal + CO₂. Used for iron (Fe₂O₃ + 3CO → 2Fe + 3CO₂ in blast furnace), zinc (ZnO + C → Zn + CO). Roasting: heating sulphide ore in air → oxide + SO₂.
