FIELD: metallurgy.
SUBSTANCE: method includes heating of kyanite to 1250-1350°C. At the same time kyanite prior to heating is mixed with solid carbon at the weight ratio from 1:0.37 to 1:1.85. Heating is carried out in atmosphere of halogen-containing gases. Produced halogenides are cooled and separated, afterwards a mixture is prepared from them with required content in the product of aluminium, silicon and other chemical elements available in kyanite. Then the mixture of halogenides is heated either in atmosphere of oxygen with production of complex oxides or in recovery atmosphere with production of alloys.
EFFECT: complex wasteless processing of kyanite concentrate.
