FIELD : chemistry. SUBSTANCE : to obtain rare-metal concentrate from chloride sublimates, formed in the process of purification of steam-gas mixture of titanium tetrachloride production, leaching of chloride sublimates is carried out with obtaining pulp. Sediment is separated, washed, obtained concentrate is annealed. Solid chloride sublimates are leached with water solution of sodium sulphate at ratio S : L, equal 1 : (3-5). Pulp is mixed, sediment is separated and after washing with water is loaded in soda solution at ratio S : L, equal 1 : (7-10). Then it is mixed, sediment is separated, washed with water and annealed. EFFECT : invention makes it possible to obtain rare-metal concentrate with reduced content of zirconium. 8 cl, 1 ex
