Abstract

Содержащий драгоценный металл минеральный материал подвергают кислотному тиоцианатному выщелачиванию для растворения драгоценного металла в виде комплекса драгоценный металл-тиоцианат. Исходный тиоцианатный выщелачивающий раствор может иметь большое молярное отношение трехвалентного железа к тиоцианату. Драгоценный металл может быть выделен из обогащенного им тиоцианатного выщелачивающего раствора, например, путем перевода драгоценного металла из комплекса драгоценный металл-тиоцианат в комплекс драгоценный металл-цианид и затем адсорбции комплекса драгоценный металл-цианид на адсорбирующем материале. Остающийся цианид в тиоцианатном выщелачивающем растворе может быть превращен в тиоцианат для дополнительного выщелачивания драгоценного металла.
