    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).
