Reduction of Iron(III) Oxide by Carbon Monoxide

Fe₂O₃ + 3CO → 2Fe + 3CO₂

ภาพรวม

Carbon monoxide reduces iron(III) oxide to metallic iron in the blast furnace. CO is oxidized to CO₂ while Fe³⁺ is reduced to Fe⁰. This is the primary reduction reaction in ironmaking, occurring in the lower-middle zone of the blast furnace at 700-1200 C.
