Abstract
Hydrometallurgy is the most suitable extractive technique for the extraction and purification of
manganese as compared to all other techniques including biometallurgy and pyrometallurgical
processes. In the hydrometallurgical processing of manganese from its ore, the leach liquors often
contain divalent ions such as iron, manganese, copper, nickel, cobalt and zinc along with other
impurities which make manganese very difficult to separate. The processes employed for solution
concentration and purification in the hydrometallurgical processing of manganese include
precipitation, cementation, solvent extraction and ion exchange. Solvent extraction also proves
more efficient and it plays vital roles in the purification and separation of the manganese as compared
to all other techniques. A detailed review of the various steps involved in the hydrometallurgical
manganese processing, concentration and purification processes and newer processes of
extraction of manganese from ores and waste materials were discussed
