For low-grade manganese oxide ores, leaching manganese is preferred when other impurity minerals are insoluble. Because MnO 2 is stable in acidic and alkaline conditions, it is necessary to transform insoluble Mn (IV) into soluble Mn (II) when leaching manganese from manganese oxide ores (Sinha and Purcell 2019). Available methods include: SO 2 reduction …
