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

Fe3O4 + 4CO → 3Fe + 4CO2

개요

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.
