FIELD: metallurgy.
SUBSTANCE: invention relates to processing methods of slag for aluminium smelting and its alloys, and also to production methods of construction materials and inorganic matters, particularly to technology of receiving of basic aluminium chloride. Processing method of aluminium-containing slag, containing aluminium nitride, includes water cleaning of soluble metals salt with regulation pH pulp. Additionally water cleaning is implemented with blowing of pulp by carbon dioxide up to receiving of meaning pH 7.0-7.5.
EFFECT: improvement of environmental conditions of manufacturing, and also ability of usage of received salt solution for regeneration of cationite filters.
