FIELD: affinage of gold. SUBSTANCE: method comprises leaching gold from gold-containing zinc sediment by chlorination thereof in water to 1000-1100 mv of oxidizing-reducing potential filtration of pulp, reducing gold with sodium thiosulfate as oxiding-reducing potential of filtrate is decreased to 500-650 mv and metallic gold sediment is separated. Method makes it possible to quickly and safety process raw materials having high content of metallic zinc to reduce expenses and to eliminate explosion hazard. Recovery of gold from gold-containing zinc sediment into the desired product is about 90%. EFFECT: more efficient recovery method. 2 ex
