摘要
用二氧化硫法处理贫软锰矿，得到含硫酸锰和连二硫酸锰的溶液，继而将该溶液进行净化，除杂，浓缩，结晶处理即得工业级硫酸锰。
A solution containing manganous sulfate and manganous dithionate was prepared from low grade pyrolusite by sulfur dioxide process. Manganous sulfate of industrial grade was obtained by purification, removal of impurities, concentration of the solution and crystallication. Manganous carbonate can be yielded by treatment of the mother liquor with ammonium acid carbonate.
