| Abstract: | This paper introduces the resource reuse route of high concentration SO2 flue gas produced incalcination of manganese slag in an electrolytic manganese enterprise,and expounds theprocess design for MnSO4 productionby flue gas desulfurization with manganese oxideore slurry. The MnSO4 productiondevice is running stable,and the SO2 mass concentration in the outlet gas is 32.1-51.9 mg/m3,which meets the design requirement for SO2 emission. The mass concentration of Mn2+ and MnS2O6 in the MnSO4 slurry produced inthe desulfurization device is (40±1) g/L and less than 5 g/L,respectively,which meets the requirements for electrolytic manganese production. |
