FIELD: non-ferrous metallurgy; extraction of noble and non-ferrous metals from tailings of concentration of polymetallic and under- account ores. SUBSTANCE: proposed method includes grinding of tailings to 40-80% class of 74 mkm, leaching with acid chloride solutions, flotation from leaching pulp, filtration, sedimentation of metals from solution followed by their separation into selective products. EFFECT: increased degree of extraction of noble and non-ferrous metals. 6 tbl, 4 ex
