1. The leachate treatment technology of electrolytic manganese slag storehouse is to treat Mn2+ and NH4+-N in the leachate of electrolytic manganese slag storehouse through chemical reagent precipitation, electrochemistry, adsorption and ammonia nitrogen stripping.

2. Dry treatment technology of electrolytic manganese slag means that electrolytic manganese slag is directly mixed with cement or chemical reagents without pyrometallurgical or wet treatment, so as to realize harmlessness of electrolytic manganese slag, stimulate its activity and provide basis for resource utilization.

3. Chemical reagent curing technology, using alkaline chemical reagents, such as CaO, MgO, Na2CO3 and Na3PO4. Manganese ions will precipitate in the form of manganese oxides or hydroxides, or produce manganese salts with low solubility products without pollution.
