Изобретение относится к гидрометаллургии благородных металлов, в частности к способам извлечения золота и серебра из концентратов, отходов электронной и ювелирной промышленности. Способ извлечения золота и серебра включает в себя обработку растворами комплексообразующих солей и пропускание электрического тока с плотностью 0,5-10 А/дм2. В качестве растворов используют растворы, содержащие тиоцианат-ионы, ионы трехвалентного железа, и рН раствора составляет 0,5-4,0. Выделение золота и серебра проводят на катоде, отделенном от анодного пространства фильтрующей мембраной. 1 с. п. ф-лы, 1 ил.The invention relates to hydrometallurgy of noble metals, in particular to methods for extracting gold and silver from concentrates, waste, electronic and jewelry industry. The method of extracting gold and silver involves treating with solutions of complexing salts and passing an electric current with a density of 0.5-10 A / dm 2 . As solutions, solutions containing thiocyanate ions, ferric ions are used, and the pH of the solution is 0.5-4.0. The selection of gold and silver is carried out on the cathode, separated from the anode space by a filter membrane. 1 sec. item f-ly, 1 ill.
