Abstract: Изобретение относится к электрохимии благородных металлов, в частности электрохлоринации, и может быть использовано при переработке вторичных металлов платиновой группы (МПГ). Способ включает обработку катализатора в электролите электрохлорирования с наложением прямого и переменного токов с предварительной активацией благородных металлов и последующим электроосаждением их на катоде в условиях уменьшения объема электролита. Предварительную активацию благородных металлов в катализаторе проводят в среде газообразных продуктов электролиза при постепенном заполнении засыпки катализатора электролитом на основе соляной кислоты. После заполнения электролитом - в инертном газе при давлении 5-10 атм. Уменьшение объема электролита в процессе ведут и контролируют за счет его переконденсации в отдельную накопительную емкость путем периодического сброса давления газов в систему конденсации до момента завершения накопления электролита в накопительной емкости. Добавляют свежий электролит до первоначального объема, повышают давление инертного газа до первоначального в 5-10 атм и повторяют цикл электроосаждения с периодическим сбросом давления. Изобретение позволяет упростить и повысить производительность процесса при обеспечении высокого процента извлечения благородных металлов. 2 пр.
