Electrolytic manganese residue harmless treatment method
The invention discloses a harmless treatment method for electrolytic manganese residues. The method comprises the following steps: crushing and levigating the electrolytic manganese residues, and adding sulphoaluminate cement clinker, an alkaline material, industrial by-product gypsum, alum and water; adjusting the water temperature, uniformly stirring to obtain a mixture, and fully reacting the mixture under a micro-negative pressure condition, and aging the reaction product to obtain the harmless electrolytic manganese residues. The method is low in cost, raw materials are easy to obtain, and the technological method is simple and easy to control. Compared with a traditional treatment method, the method has the advantages that calcination treatment at high temperature is not needed, drying is not needed, the electrolytic manganese residue treatment speed is greatly increased, meanwhile, energy consumption is greatly reduced, and the electrolytic manganese residue treatment speed is greatly increased. The method is suitable for large-scale low-cost rapid harmless treatment of electrolytic manganese residue discharge enterprises.
本发明公开了一种电解锰渣无害化处置方法，包括以下步骤：将电解锰渣经破碎、磨细后加入硫铝酸盐水泥熟料、碱性物料、工业副产物石膏、明矾和水，调节水温后搅拌均匀得到的混合物，将混合物在微负压条件下充分反应，经陈化后得到无害化电解锰渣。本发明方法成本低、原材料易得，工艺方法简单、易控制，与传统处理方法相比，也不需要在高温下进行煅烧处理，无需烘干，处理电解锰渣的速度大幅提高，同时极大程度上降低了能耗，处理电解锰渣的速度大幅提高，适用于电解锰渣排放企业进行大批量低成本快速无害化处置。
