Abstract

Описан способ извлечения золота из золотосодержащего органического раствора, содержащего растворенное золото. Способ включает контактирование золотосодержащего органического раствора с водным реэкстрагирующим раствором с целью извлечения золота из золотосодержащего органического раствора в водный реэкстрагирующий раствор. Водный реэкстрагирующий раствор, содержащий золото, отделяют от органического раствора. Отделенный водный реэкстрагирующий раствор, содержащий золото, приводят в контакт с восстановителем, содержащим метабисульфит натрия, с целью восстановления золота из водного реэкстрагирующего раствора.
