| description | The invention discloses a harmless treatment method for comprehensive utilization of ammonium sulfate generated in the metal electrolysis process, and particularly relates to the technical field of ammonium sulfate harmless treatment. The method comprises the following steps: respectively carrying out crushing treatment on ammonium sulfate and slaked lime generated in the metal electrolysis process; fully and uniformly mixing the crushed ammonium sulfate and slaked lime in proportion, adding water or filtrate, carrying out mechanical stirring reaction at normal temperature and normal pressure, and collecting ammonia gas obtained by the reaction while reacting to obtain gypsum slurry; after the reaction is finished, inputting the obtained gypsum slurry into a filter press for filter pressing treatment, and continuously collecting ammonia gas obtained by filter pressing in the filter pressing process to obtain gypsum slag; performing low-temperature drying treatment on the obtained gypsum slag to obtain initial |
