FIELD: noble metal metallurgy. SUBSTANCE: method relates, particularly, to gold and silver refining and includes leaching of gold-silver product from chlorine slag and its subsequent processing. Leaching is carried out with sulfite solution with weight concentration of Na2SO3 equalling 300-400 g/l and liquid:solid ratio of (14-15):1. Gold-containing product is separated from pulp and silver is precipitated from solution. EFFECT: increased efficiency of chloride slag processing; reduced power consumption. 2 tbl, 6 ex
