Decomposition of Iron(II,III) Oxide (Direct Reduction)

Fe₃O₄ + 4CO → 3Fe + 4CO₂

Descripción general

Iron(II,III) oxide (magnetite) is reduced by carbon monoxide to produce metallic iron and carbon dioxide. This is one of the key reactions in the blast furnace for iron smelting. The process operates at temperatures above 700 C and is the foundation of the steel industry.
