| Abstract: | Industrial residue from production of KMnO4 contains much high valence of Mn compounds.It leads to the waste of manganese and the risk of environmental pollution.To recycle the manganese in the slag,glucose was used as reductant in acidic solution.Factors associated with leaching rate were investigated such as dosage of glucose,concentration of sulphuric acid and leaching temperature.And the process conditions to recover the manganese by chemical oxidation method were studied.Results indicated that manganes... |
