FIELD: nonferrous metallurgy. SUBSTANCE: polymetal ores tailings process is exercised using chloride lixiviation with acidulous solution, that has 100 300 g/l chloride sodium, till final value pH is 1,5 2.5. Cake, produced during lixiviation, is floated off with production of pyritic concentrate and dump tailings. Hydroxides of metals are settled in collective product from lixiviation solution. Then metals are separated wit production of selective products. EFFECT: increased efficiency. 4 tbl
