Extraction and separation of manganese and iron from. Jan 15, 2019· 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

12/10/2018· Manganese (Mn) extraction from iron-rich pyrolusite ore with cheap sulphur dioxide is considered to be the most promising method with advantages of rapid leaching rate and high leaching efficiency. Nevertheless, co-dissolution of iron (Fe) with manganese has limited the development of its commercial practice. In this work, the separation kinetics and
