Abstract
The application discloses a harmless treatment method of electrolytic manganese residue, and comprises the following steps: (1) crushing electrolytic manganese residue and mixing the residue with additives to obtain mixed residue; the additives comprise porous silico-aluminate material and alkaline material; (2) performing roasting treatment on the mixed residue to obtain harmless electrolytic manganese residue. The harmless treatment method of electrolytic manganese residue adopts a combined roasting process of adding additives (including porous silico-aluminate material and alkaline material) to realize the harmless treatment of electrolytic manganese residue, and has good solidification effect on the electrolytic manganese residue, and realizes efficient treatment of manganese, ammonia nitrogen and water-soluble salt.
