Question

Which reducing agents are used to reduce haematite ore into metallic iron? Give reactions.

Answer 1

Haematite ore is reduced using coke and CO. Carbon in the coke is converted to CO₂ .

∴ C and CO together reduce Fe₂ O₃ to metallic iron.

\[\ce{Fe2O3 + 3C -> 2Fe + 3CO}\]

\[\ce{Fe2O3 + 3CO -> 2Fe +3CO2}\]
