Method for producing manganous-manganic oxide and co-producing lead-silver alloy
The invention relates to a method for producing manganous-manganic oxide and co-producing lead-silver alloy, which comprises the following steps: carrying out leaching reaction on electrolytic manganese anode slag by using sulfuric acid and hydrogen peroxide to generate a manganese sulfate solution, and carrying out filter pressing to remove lead-rich slag for later use; filtering the filtrate through a ceramic membrane, adding industrial-grade manganese dioxide, stirring, slowly adding stronger ammonia water, reacting for two hours, heating to 60 DEG C, filtering, washing filter residues with water, spray-drying, demagnetizing and packaging to obtain a finished product manganous-manganic oxide for sale, adding lime milk into the filtrate for deamination to prepare ammonia water, and carrying out dense filter pressing and drying on the emulsion to generate a calcium sulfate solid. And drying, crushing, packaging and selling, and performing multi-effect evaporation on the filtrate to prepare deionized water for the previous process steps. According to the method, the electrolytic manganese production process is researched, high-valued comprehensive utilization of the electrolytic manganese anode slag is achieved, and high-quality development of the manganese industry is promoted.
一种生产四氧化三锰联产铅银合金的方法，将电解锰阳极渣用硫酸加双氧水浸取反应，生成硫酸锰溶液，压滤去除富铅渣备用。再将滤液经陶瓷膜过滤加入工业级二氧化锰搅拌，同时缓慢加入浓氨水反应两小时，加温至60℃过滤，滤渣经水洗、喷雾干燥、除磁、包装即为成品四氧化三锰出售，滤液加入石灰乳脱氨制备氨水，乳液经浓密压滤、烘干生成硫酸钙固体，烘干破碎包装出售，滤液经多效蒸发制去离子水用于前工艺步骤。富铅渣加入焦炭用烟化炉冶炼回收铅和贵金属，本方法通过对电解锰生产工艺的研究，实现电解锰阳极渣高值化综合利用并推动锰行业高质量发展。
