(i) oxidation of carbon and carbon monoxide to carbon dioxide; (ii) reduction of ferric oxide to iron.



#C(s) + 1/2O_2(g) rarr CO(g)#


#Fe_2O_3(s) + 3CO(g) rarr 2Fe(l) + 3CO_2(g)#

If you ever have the opportunity to visit a working blast furnace, where hot gases are blasted thru a pile of coke and ore to give iron, do so. You feel very small given the size and sound of the furnace.
