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... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.Get a Quote Leave Message
