In order to collect iron, it must be extracted from iron ores in a blast furnace. Iron ores such as haematite and magnetite contain iron oxide and, in order to collect the iron, the oxygen must be removed from the iron oxide. By heating iron oxide with carbon (in the form of coke), it is able to be reduced to iron.
