REMOVAL OF MANGANESE FROM ACID MINE DRAINAGE

carbonate is fairly insoluble at moderate pH; a 2 mg/L can be established through manganese carbonate control at pH Hem and Lind (1983) note that MnCO3 (rhodochrosite) precipitates should only be present in systems where carbonate is high and oxygen depleted. They do not discuss the fact that normally, the manganese carbonate is quickly oxidized to the appropriate oxide with the release of .

ENVIRONMENTAL ASPECT OF MANGANESE CHEMISTRY

manganese in natural waters that are essentially free of anthropogenic sources can range from 10 to >10000 g dm 3, while tap water can typically contain >1 mg dm 3. However, manganese concentrations in natural surface waters rarely exceed 1000 g dm 3 and are usually less than 200 g dm 3. Average levels in drinking water are 4 g dm 3 [29, 55].
