FIELD: gold bearing alloys processing and gold extraction. SUBSTANCE: method provides for electrolytic solution of initial alloy under application of alternating asymmetric current with half-cycles of positive and negative signs. Process is carried out under voltage of 0.9 1.1 V, current intensity correspondingly of 330 350 and 30 50 A and definite ration of number of positive and negative sign half-cycles. EFFECT: method allows to process effectively gold alloys with high degree of silver, bismuth, lead and tin impurities.
