Magnetite and hematite are iron oxides; however, the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed The second step in the process is calcination or roasting of the ore, which removes certain impurities, carbon dioxide and other substances
