اقرأ أكثرHow is Iron Ore Mined
Iron is an element that is not found in Free State, but rather in the form of its ores or rocks. The most commonly found ores of iron are Hematite and Magnetite. These are oxides of iron that are extracted from beneath the surface of the earth's crust and sent to blast furnaces to make pig iron. This iron is then used to manufacture steel.Web
