Outline the process of extracting iron from hematite using a blast furnace, focusing on: (a) the combustion of carbon (coke) for heat and carbon dioxide production (b) the conversion of carbon dioxide to carbon monoxide (c) the reduction of iron(III) oxide by carbon monoxide (d) the thermal breakdown of calcium carbonate to yield calcium oxide (e) the creation of slag. Symbol equations are not necessary.
