FIELD: metallurgy.
SUBSTANCE: proposed method comprises preparing leaching solution bearing gold, and gold sorption by macroporous resin containing alkyl amine functional groups in amount of 0.01-1.0 mmol/g and 3-12% of cross-links with water retaining capacity making, at least, 30%, and specific surface area varying from 400 to 1200 m2/g. After sorption, gold is eluted.
EFFECT: higher yield of gold.
