Steel production Materials used to produce pig iron Coal—as coke—used to supply carbon. In a blast furnace, ore is heated in the presence of carbon—this allows oxygen in the ore to react with carbon to form gases. Limestone—helps to remove impurities Iron ore—processed ore at the start of the process has about 65% iron.
