FIELD: metallurgy.
SUBSTANCE: method for extracting nickel from nickel-containing production solutions of sulphuric underground or heap leaching involves nickel sorption on cation-exchange resin of chelate type with functional group bis(2-piridyl methyl)amino. After sorption the nickel desorption and strippant treatment is performed. Prior to strippant treatment, ferric iron is removed from it by sorption on anion-exchange resin in 
in the shape of at pH=1.6-2.4.
EFFECT: reducing the number of ferric iron prior to treatment of nickel-containing solutions in order to improve nickel extraction.
