FIELD: metallurgy.
SUBSTANCE: extraction method of nickel from solutions or pulp of ores leaching includes ion-exchange resin sorption of nickel with following nickel desorption by solution of acid and processing of stripping. Additionally sorption is implemented from solutions or pulp, containing nickel and copper. After desorption of nickel from ion exchanger it is extracted copper by solution of ammonia and ion exchanger is returned to sorption.
EFFECT: increasing of nickel extraction ratio.
