Iron Ore

Iron ores are rocks and minerals from which metallic iron can be economically extracted. Iron ore are the raw materials to produce pig iron that is the main source of making steel. For iron ore beneficiation, there are multiple stages including crushing, grinding, classification and separation. Firstly, by crushers, raw iron ores can be crushed into little particles. Next, those particles would be sent into grinding mills to be ground into fine powders. Finally, through specific beneficiation methods such as gravity separation and flotation, iron concentrates can be got.
