Manganese metallurgy review. Part I: Leaching of ores

Low grade manganese ores (< 40%) are conventionally processed by pyrometallurgical reductive roasting or melting followed by hydrometallurgical processing for production of chemical manganese dioxide (CMD), electrolytic manganese (EM) or electrolytic manganese dioxide (EMD).

01/12/2007· 2.3. Manganese pyro-hydrometallurgy. A pyrometallurgical pre-treatment followed by hydrometallurgical processing plays an important role in the treatment of low grade manganese ores and manganese sea nodules containing Ni, Co and Cu values as their oxides. These metal oxides in the nodules often occur in the lattices of iron and manganese minerals. Therefore, breaking up these

However, this increase was not remarkable in the later period from 30 to 120 min with a slight growth in the leaching efficiency from 79.6% to 84.6%. This observation indicated that the leaching activity of semi-oxidized manganese ore in hydrometallurgy process was relatively low compared to manganese dioxide, which was reported by Veglio .
