FIELD: metallurgy.
SUBSTANCE: method involves supply of solution with high content of cobalt, which contains cobalt, nickel and copper; sorption by means of contact of the above solution with N-(2-hydroxypropyl)picoline amino resin. Selective elution of cobalt, nickel and copper is performed after sorption by means of continuous gradient acidic elution. At that, pH of the above solution is less than or equal to 2.
EFFECT: reducing the costs and increasing the efficiency of the method.
