Extracting iron from iron ore using a Blast Furnace. The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke. Coke is produced by heating coal in the absence of air. Coke is cheap and provides both the reducing agent for the reaction and also the heat source.
mining iron ore costs are omitted – energy/machinery involved in digging out the ore, crushing it, transporting the ore, and the cost of actually extracting the iron from its finite ore resource – chemicals needed (coke, limestone), constructing and running a blast furnace; So, scrap metal merchants are doing a roaring trade at the moment.
