FIELD: metallurgy.
SUBSTANCE: method of nickel extraction from solutions or pulp of ores leaching includes purification of solutions or pulps by means of extraction from them of iron and copper and following nickel ion-exchange resin adsorption. After nickel adsorption it is implemented its ion-exchange resin desorption and processing of stripping. Additionally before nickel adsorption from solutions or pulps there are extracted iron and copper, initially by deposition of iron at pH 2.5-3.0, and then sorption of copper and residue of iron on ion-exchange.
EFFECT: increasing of nickel extraction ratio.
