What's the Process of Iron Smelting?
08/01/2021 · Reduction of iron. In blast furnace, iron is not directly reduced from high valence oxide, but through a process of reduction from high valence oxide to low valence oxide, and then from low valence oxide to iron: Fe2O3 → Fe3O4 → FeO → Fe. The reduction of iron mainly depends on carbon monoxide gas and solid carbon as reducing agent.
