| Abstract: | An additional experiment,in which reduced pyrolusite(made in laboratory)is used as absorption agent in wet desulphurization to produce MnSO4·H2O,has been done in a foam tower at a smelting plant.Optimum conditions for both reduction of pyrolusite and absorption of SO2 are obtained and pure of 95% MnSO4·H2O has been produced by primary crystallization of the absorption mother liquor. |
