METHOD FOR PRODUCING ORGANOMINERAL SORBENT OF NON-FERROUS METALS ON THE BASIS OF ORE CONCENTRATION WASTES

摘要

FIELD: metallurgy.SUBSTANCE: sorbent is produced on the basis of mining operations waste - copper-nickel ore tailings, taken from a tailing impoundment of a process plant, which consist of more than 60% of serpentine Mg[SiO](OH). Waste is grounded to fraction of -0.063 mm, then baked at a temperature of 650-700°C and the surface is modified with an alcoholic solution of dimethylglyoxime. The sorption capacity of the obtained material for nickel ions is 190 mg/g.EFFECT: improvement of the sorbent produced.3 cl, 1 dwg, 3 ex
