METHOD OF RECOVERING PRECIOUS METALS FROM ION-EXCHANGE RESINS CONTAINING GOLD, SILVER, AND PLATINUM METALS

摘要

FIELD: precious metal hydrometallurgy. SUBSTANCE: in a method of selectively recovering precious metals from ion-exchange resins, first gold and silver ions are eluted with thiourea sulfuric acid solution and then sorbed ions are eluted with thiourea hydrochloric acid solution. EFFECT: ensured selectivity of recovery.
