The extraction of iron occurs in the blast furnace. The term "blast" refers to the supply of combustion air above atmospheric pressure. The concentrated ore is reduced to a liquid chemical condition in the blast furnace. The concentrated iron ore, coke, and limestone are supplied from the top and a blast of hot air is forced into the bottom of ...

Download. Iron (Fe) is a metallic element that constitutes % by weight of the Earth's crust and is the fourth most abundant element in the crust. Iron ores are rocks from which metallic iron can be economically extracted. The principal iron ores contain hematite (Fe 2 O 3) and magnetite (Fe 3 O 4 ). Hematite is an iron oxide mineral.
