| Study on the Separation of Impurities from Manganese Sulfate |
| Peng Ai Guo; et al （Hunan Research Institute of Chemical Industry; Changsha 410007; China） |
| Abstract：New process was developed for the separation of impurities in manganese sulphate in two stages. At first, Large amount of impurities could be separated in the form of sulphite, then use chelating agent to subside the residuary impurities. The total separation efficiency of nickel is 99%, and cobalt is above 98%, the loss of manganese in the process is only 2.7%. The amount of heavy metal impurities in the manganese sulphate after refining are less than 10mg/kg. |
