Zusammenfassung:	recovery of gold from highly mineralized solutions, for instance, reusable solutions of potassium and potassium-magnesium production, and in- passing recovery of gold from process solutions. SUBSTANCE: method includes treatment of highly mineralized solution with gold content of, at least, 10 mcg/1 with flocculant based on polyacrylamide and oxyethylated aliphatic acid in weight ratio of 1(2-3) in amount of 0.2 mg/1 and 0.4-0.6 mg/1, respectively, and separation by flotation. Then, solution is treated with mixture of butyl xanthate and AEROFLOT composition in weight ratio of 1:1 and in amount of 10-20 mg/1 with subsequent separation of gold- containing concentrate by flotation. EFFECT: higher recovery of gold from highly mineralized gold-containing chloride solutions and produced concentrate rich in gold. 2 cl, 1 tbl, 3 ex
