2019-8-1 The presence of manganese in the iron ores, however, makes the separation process more complex due to its similar physical and chemical characteristics to iron [19,20,21,22,23]. Manganese can be extracted from its oxide ores by either reduction roasting–magnetic separation, reduction roasting-acid leaching, or direct reductive leaching [ 24 , 25 , 26 ].

2019-1-15 In the oxide type manganese ore, the manganese is often present in the insoluble form of Mn 4+ and iron often exists in the state of Fe 3+. In order to obtain soluble Mn 2+ , Mn 4+ must be converted into Mn 2+ , therefore, reductants are applied to reduce Mn 4+ into Mn 2+ during the acid leaching process (Named as direct reduction leaching).
