Claims (2)

1. A method for extracting nickel from spent solutions of galvanic production, including sorption of nickel on an ion exchange resin, its regeneration with acid and washing with water, characterized in that the sorption of nickel is carried out on at least two ionite filters - first, on the first one, before nickel ions slip into the filtrate, then on both filters until the exchange capacity of the first filter is completely saturated, after which it is taken out for regeneration, and sorption is continued on the second filter with simultaneous regeneration of the first spent filter, according to at the end of which sorption of nickel is carried out again on both filters until the second filter is withdrawn for regeneration, etc., and the regeneration is carried out in four stages: first, the ion exchanger is pumped from above with compressed air for 5-10 minutes, then the ion exchanger filter is filled with a regeneration solution - acid to a level that does not exceed the upper level of the ion exchanger by more than 5 - 10 cm, and the acid is supplied from below, the ion exchanger is kept in contact with the acid for 20 - 35 minutes, after which the acid is fed from above, the regenerate contains n Of nickel Ni> 40.0 g / l and a pH of> 4.0 in the manufacture of recycled for the preparation of electrolyte reclaimed remainder used to prepare the regenerating solution, and washing of the ion exchanger is carried posleregeneratsionnuyu deionized water, wherein the water supply is carried out co-currently.
 2. The method according to p. 1, characterized in that the granite iminodiacetate ion exchanger is used as the ion exchange resin, the granule sizes of which are 0.5-1.0 mm.
