Fe2O3 + 3CO → 2Fe + 3CO2.In the areas of the furnace where the temperature is high enough, the carbon from coke itself can also reduce the iron oxide, giving off more carbon monoxide. The pure iron then melts and goes to the bottom of the furnace. The iron ore itself is not pure ore.
iron (III) oxide + carbon ==> iron + carbon dioxide. 2Fe2O3 + 3C ==> 4Fe + 3CO2. 2Fe2O3(s) + 3C (g) ==> 4Fe (l/s) + 3CO2(g) (equation with state symbols) I'm afraid there are quite a few possible equations and most do occur to some extent somewhere in the blast furnace.
