Abstract

В заявке описан способ повышения концентрации металлического золота, включающий обработку металлической золотосодержащей композиции в выщелачивающем растворе. Этот выщелачивающий раствор выбирают таким образом, чтобы обеспечить растворение примесей, содержащихся в этой металлической золотосодержащей композиции, без растворения заметного количества металлического золота. В предпочтительном варианте этот выщелачивающий раствор представляет собой раствор, характеризующийся высокой константой кислотной диссоциации, высоким окислительным потенциалом и сильной тенденцией к комплексообразованию с катионами. В предпочтительном варианте предлагаемый способ перед выщелачиванием включает стадии кальцинирования золота в окислительной атмосфере или тонкого распыления. Металлическую золотосодержащую композицию можно повторно кальцинировать и подвергать выщелачиванию до достижения целевой степени чистоты золота.Международная заявка была опубликована вместе с отчетом о международном поиске.
