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...

Iron and Industrial Revolution in Britain Early iron smelting used charcoal as both the heat source and the reducing agent By the 18th century the availability of wood for making charcoal had limited the expansion of iron production so England became increasingly dependent on Sweden from the mid17th century and then from about 1725 on Russia for the iron required for industry
