What is the chemical change involved in obtaining iron from iron ore?
Iron ore is primarily obtained from the minerals hematite (Fe2O3) and magnetite (Fe3O4). To obtain iron, you need to remove the oxides while changing the charge on the iron. Because the bonds to oxygen atoms are very strong, carbon monoxide is typically used in a process called smelting.
