Industrial Extraction of Iron in the Blast Furnance
Iron(III) oxide is reduced to iron by carbon monoxide: Fe2O3 + 3CO -> 2Fe + 3CO2. The limestone acts as a flux and reacts with the impurities in the iron ore to form slag: CaCO3 -> CaO + CO2; CaO + SiO2 -> CaSiO3 (slag). Both the molten iron and slag collect at the bottom of the furnace. The less dense slag floats on the surface of the iron.
