Method for solidifying electrolytic manganese residues by adopting magnesium phosphate cement
The invention discloses a method for solidifying electrolytic manganese residues by adopting magnesium phosphate cement, which comprises the following steps: 1) drying the electrolytic manganese residues to constant weight, and then grinding the electrolytic manganese residues by adopting a ball mill; 2) uniformly stirring the electrolytic manganese residues and dead burned magnesium oxide to obtain a mixture A; 3) adding monopotassium phosphate and borax into water, and completely dissolving to obtain a mixture B; 4) fully mixing the mixture A and the mixture B to obtain slurry; (5) injecting the slurry into a cubic mold, maintaining for 24 hours at room temperature, demolding, and standing for 28 days to obtain a harmless building block; the mass parts of various substances are respectively as follows: 845 parts of electrolytic manganese residues, 100 parts of dead burnt magnesium oxide, 25 parts of monopotassium phosphate, 2 parts of borax and 369.36 parts of water. The method for solidifying the electrolytic manganese residues by adopting the magnesium phosphate cement has the beneficial technical effects that according to the scheme, the selection of raw materials for solidifying the electrolytic manganese residues is widened, the treatment cost is low, and the recycling efficiency of the electrolytic manganese residues can be effectively improved.
本发明公开了一种采用磷酸镁水泥固化电解锰渣的方法，所述方法包括：1）将电解锰渣烘干至恒重，然后采用球磨机对电解锰渣进行研磨；2）将电解锰渣和重烧氧化镁搅拌均匀，得到混合物A；3）将磷酸二氢钾和硼砂加入水中，完全溶解后，得到混合物B；4）将混合物A和混合物B充分混合后，得到浆体；5）将浆体注入立方体模具中，在室温下养护24小时后脱模，静置28天后得到无害化砌块；各种物质的质量份数分别为：电解锰渣845份、重烧氧化镁100份、磷酸二氢钾25份、硼砂2份、水369.36份。本发明的有益技术效果是：提出了一种采用磷酸镁水泥固化电解锰渣的方法，该方案拓宽了固化电解锰渣的原料选型，且处理成本较低，能有效提高电解锰渣回收利用效率。
