Способ относится к области гидрометаллургии благородных металлов и может быть использован в частности для извлечения золота из медьсодержащих концентратов. Поставленная задача достигается тем, что в способе, включающем цианирование, фильтрацию, цементацию и плавку цементных осадков на слиток, перед фильтрацией концентрацию свободного цианида в пульпе снижают до 0 - 5 мг/л, а перед цементацией концентрацию свободного цианида в растворе восстанавливают. Это позволяет повысить извлечение золота в слиток в 1,4 раза по сравнению с известным способом.The method relates to the field of hydrometallurgy of noble metals and can be used in particular for the extraction of gold from copper-containing concentrates. The task is achieved by the fact that in the method including cyanidation, filtration, cementation and smelting of cement sediments on an ingot, before filtration the concentration of free cyanide in the pulp is reduced to 0-5 mg / l, and before cementation the concentration of free cyanide in the solution is reduced. This allows you to increase the extraction of gold in the ingot 1.4 times compared with the known method.
