Изобретение относится к области гидрометаллургии благородных металлов и может быть использовано для извлечения серебра, платины и палладия из растворов, образующихся при электролизе серебра. Способ заключается во введении в отработанный электролит смеси реагентов, состоящей из хлорида и сульфида натрия при их соотношении 1 : 4,5 и расходе реагента, равном 95 - 105% по хлориду натрия от стехиометрии в расчете на серебро. Степень осаждения серебра и палладия - 100%, платины - 89,4%. Остаточное содержание металлов в растворе менее 27 мг/дм3.The invention relates to the field of hydrometallurgy of noble metals and can be used to extract silver, platinum and palladium from solutions formed during the electrolysis of silver. The method consists in introducing into the spent electrolyte a mixture of reagents consisting of sodium chloride and sodium sulfide at a ratio of 1: 4.5 and a reagent consumption equal to 95–105% for sodium chloride from stoichiometry in the calculation of silver. The degree of deposition of silver and palladium - 100%, platinum - 89.4%. The residual metal content in the solution is less than 27 mg / dm 3 .
