The principal ore of iron, from which iron is extracted is

  1. Magnetite
  2. Hematite ✓
  3. Bauxite
  4. Calcite
Explanation

Hematite is the main iron ore. It contains iron(III) oxide (Fe₂O₃). Most iron production uses hematite because it has high iron content.

Magnetite also contains iron but is less common. Bauxite contains aluminum, not iron. Calcite contains calcium carbonate.

Remember: Hematite looks reddish-brown. The red color comes from iron oxide.
