FIELD: hydrometallurgy. SUBSTANCE: invention relates to technologies of separating metals from aqueous solutions and can be used in treatment of complex-composition waste waters to remove cations of a variety of metals. Method involves filtration of waste water through adsorbents: first through birch activated carbon layer and then through layer of magnetic products of 2:1 ash-slag mixture. The latter contains coal combustion waste subjected to wet magnetic separation and isolation of fraction 0.3-0.005 mm. EFFECT: simplified process and decreased expenses. 2 dwg, 5 tbl, 6 ex
