Treatment method of electrolytic manganese residues
The invention provides a treatment method of electrolytic manganese residues. The method comprises the following steps that electrolytic manganese residues and a modifier are subjected to sealed stirring and negative pressure suction, modified manganese residues and first flue gas are obtained, and the first flue gas is used for preparing an ammonia water solution; the modified manganese slag and a flux are mixed for oxidation smelting, first molten slag and second flue gas are obtained, and the second flue gas is used for preparing concentrated sulfuric acid; mixing the first slag with a reducing agent and an adjusting agent for reduction smelting to obtain second slag, third flue gas and reduced metal liquid, and adding a desulfurization and dephosphorization agent into the reduced metal liquid for desulfurization and dephosphorization to obtain desulfurized and dephosphorized metal liquid; and quenching and curing the second slag to obtain glass slag, mixing the glass slag with an exciting agent, and grinding to obtain the active micro powder. According to the method, multiple sulfur-containing multi-metal solid wastes in the electrolytic manganese residues can be cooperatively treated, ammonia, sulfur and valuable metal resources in the manganese residues are fully recycled, comprehensive utilization of all solid wastes in the whole process is achieved, and the social and economic benefits are large.
本发明提供了一种电解锰渣的处理方法。该方法包括以下步骤：将电解锰渣与改性剂进行密封搅拌、负压抽吸，得到改性锰渣和第一烟气，第一烟气用以制氨水溶液；将改性锰渣与熔剂混合进行氧化熔炼，得到第一熔渣和第二烟气，第二烟气用以制浓硫酸；将第一熔渣与还原剂、调整剂混合进行还原熔炼，得到第二熔渣、第三烟气和还原金属液，向还原金属液中加入脱硫磷剂进行脱硫磷，得到脱硫磷金属液；将第二熔渣进行急冷固化，得到玻璃渣，将玻璃渣和激发剂混合进行粉磨，得到活性微粉。本发明能够协同处理电解锰渣中多种含硫多金属固体废物，充分地回收锰渣中的氨、硫和有价金属资源，并实现全流程内所有固废的综合利用，社会经济效益大。
