Method for solidifying electrolytic manganese slag by utilizing phosphogypsum waste slag
The invention discloses a method for curing electrolytic manganese slag by using phosphogypsum waste slag, which comprises the following steps: uniformly stirring and mixing electrolytic manganese slag, phosphogypsum waste slag, phosphate and water, adding a softening curing agent, uniformly stirring, sealing, standing, reacting, carrying out compression molding, and curing. According to the method, the addition amount of the curing agent during cementing curing of electrolytic manganese is reduced, the obtained consolidated body is high in unconfined compressive strength and high in softeningcoefficient, effective consolidation resource utilization of electrolytic manganese residues and phosphogypsum can be achieved, high-consumption resource consumption of electrolytic manganese materials and phosphogypsum waste slag in the aspects of road base and dam body materials is improved, pollution of the electrolytic manganese slag and phosphogypsum to the mine environment is reduced, and meanwhile waste is treated with waste.
本发明公开了一种利用磷石膏废渣固化电解锰渣的方法，该方法是将电解锰渣、磷石膏废渣、磷酸盐和水搅拌混合均匀，再加入软化固化剂搅拌均匀、密封、静置反应后，压制成型，养护。该方法降低了电解锰进行胶结固化时固化剂添加量，获得的固结体无侧限抗压强度较高，软化系数强，该方法可以实现电解锰渣和磷石膏的有效固结资源化利用，以提高电解锰物料及磷石膏废渣在道路基层及坝体材料方面高耗量资源化消纳，降低电解锰渣及磷石膏对矿山环境的污染，同时实现了以废治废。
