FIELD: metallurgy.
SUBSTANCE: method includes feed into fluid-bed furnace, its dewatering, and dust collection in scrubbers with further its extraction from scrubbers. After dust extraction from scrubbers it is melted in tank at temperature 500-580°C. Into melted carnallite dust it is added melted magnesium chlorides at mass ratio melted carnallite dust to melted magnesium chlorides equal (4-6):1. Received compound is warmed up till temperature 720-850°C, is settled during 0.5-2.0 hours and directed to the further usage as raw material for electrolytic production of magnesium and chlorine. In the capacity of melted magnesium chlorides it is used by-product of spongy titanium production.
EFFECT: invention allows make the most efficient use of wastes of production; to extend raw materials base and to save raw materials.
