METHOD FOR PRODUCING ALUMINIUM-CONTAINING COAGULANT

摘要

FIELD: non-ferrous metallurgy; utilization of wastes; environmental control. SUBSTANCE: slags resulting from production of aluminium alloys by smelting are subjected to treatment with concentrated sulfuric acid. Resulting product is filtered, followed by neutralizing filtrate with ammonia. Filtrate thus-neutralized is cooled down to precipitate crystals therefrom. Crystals are washed with water/acetone mixture. EFFECT: higher efficiency.
