Ironmaking 101 – From Ore to Iron with Blast Furnaces
Ironmaking Blast Furnace Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impuritiesBlast furnaces produce pig iron from iron ore by the reducing action of carbon (supplied as coke) at a high temperature in the presence of a fluxing agent such as limestoneIronmaking blast furnaces consist of several zones: a crucibleshaped hearth at the bottom of the furnace; an intermediate zone called a bosh between the hearth and the stack; a vertical shaft (the stack) that extends fromBlast furnace | metallurgy | Britannica
