Abstract

Для обеспечения в значительной степени важного и экономичного способа извлечения золота или серебра представлен способ извлечения благородных металлов из руд, содержащих благородные металлы, например золото или серебро, с помощью водного аммиачно-тиосульфатного выщелачивающего раствора. После выщелачивания руды водным аммиачно-тиосульфатным раствором выщелачивающий раствор контактируют с экстрагентом благородного металла для экстракции благородного металла из выщелачивающего раствора, после которой благородный металл реэкстрагируют из экстрагента для образования концентрированного раствора благородного металла, из которого благородные металлы можно извлечь посредством общепринятых способов, например электролиза. Экстрагентами являются такие соединения, которые имеют гуанидильную функциональную группу или функциональную группу четвертичного амина, смешанного со слабой органической кислотой, например фенолом. В способе образуются новые тиосульфатные комплексы благородных металлов с гуанидильными или четвертичноаминовыми экстрагентами.Международная заявка была опубликована вместе с отчетом о международном поиске.
