Mn Forms and Environmental Impact of Electrolytic Manganese Residue

摘要：

Mn Forms and the effect on environment of electrolytic manganese residue (EMR) in Chongqing have been investigated through water extracting and sulpharic acid leaching. The ways of comprehensive utilization on EMR has been discussed in this research. The results show that the forms of Mn in EMR are chiefly water soluble Mn(Ⅱ), the manganese carbonate and manganese dioxide. The groundwater pollution and the eco-environment damage will present if the EMR is randomly stacked and thrown. Having appropriate methods, the EMR may be used as recovery manganese(e.g. manganese sulfate and producing Fe-Mn bimetal oxide). The second residue from EMR can prepare water disposal agent.
