Abstract

The gradual depletion of high-grade mineral resources and the steady increase in demand for precious metals have led to growing interest in efficient recovery technologies. Sorption processes play a significant role in the extraction of gold and silver from cyanide solutions due to their operational efficiency and technological simplicity. This study presents a comparative investigation of ion-exchange resins and activated carbon used for precious metal recovery. Laboratory experiments were performed under controlled cyanidation conditions to assess sorption efficiency and kinetic behavior. The obtained results show that activated carbon provides higher recovery rates, particularly for silver, while ion-exchange resins demonstrate limited efficiency under identical conditions. These findings emphasize the importance of sorbent selection and process optimization for improving precious metal extraction.
