Annotation: The paper considers the possibility of gold recovery from pond waters of a tailings storage facility at a hydrometallurgical gold production plant. The chemical and ionic composition of process waters is analyzed, and experimental results on the sorption recovery of gold and silver in dynamic mode using activated carbon and ion-exchange resin are presented. The study demonstrates that activated carbon exhibits higher sorption capacity and selectivity for gold and silver compared to ion-exchange resin under conditions of high water mineralization. The kinetics of gold sorption on activated carbon was investigated, showing that the maximum sorption capacity of about 0.8 mg/g is achieved after approximately 90 hours. The obtained results confirm the feasibility of involving tailings pond waters in processing in order to enhance precious metal recovery and improve the environmental performance of hydrometallurgical operations.

Keywords: gold, pond water, tailings storage facility, sorption, activated carbon, ion-exchange resin, process water, hydrometallurgy, sorption kinetics, selectivity.
