Process of extracting manganese from ore - GEN

The method of extracting manganese compounds from complex carbonate ores containing manganese and iron which comprises calcining the ore to eliminate the carbonates, sulphatizing the calcined product, roasting the sulphatized product in the presence of air at a temperature of approximately 6500 C. until the iron is oxidized into a condition relatively insoluble in water, leaching with water, separating soluble manganese sulphate from the insoluble residue, precipitating a manganeseCited by: 11

Extraction and separation of manganese and iron from ...

Jan 15, 2019· In the oxide type manganese ore, the manganese is often present in the insoluble form of Mn 4+ and iron often exists in the state of Fe 3+. In order to obtain soluble Mn 2+ , Mn 4+ must be converted into Mn 2+ , therefore, reductants are applied to reduce Mn 4+ into Mn 2+ during the acid leaching process (Named as direct reduction leaching).Cited by: 71
