Mineralogical investigations have also revealed that Manganese occurs in the minerals as higher oxides, mainly pyrolusite (MnO 2).Since MnO 2 is stable in direct acid or alkali dissolution, the possible reduction of the insoluble tetravalent manganese(IV) to soluble bivalent manganese(II) is necessary to recover manganese from its ores. The reduction of …
