Extraction and separation of manganese and iron from ...

2019-01-15  Physical separation techniques have a relatively inferior separation effect on Mn and Fe due to the similar physical properties of the manganese and iron minerals as well as the complex mineralogy of many Fe-Mn ores. Direct reduction leaching of Fe-Mn ores with oxalic acid and methanol presents better selective leaching of manganese and iron. However, it’s uneconomical owing to the
