Abstract

Изобретение относится к металлургии благородных металлов, в том числе золота, может быть использовано при переработке как низкопробного, так и высокопробного первичного и вторичного драгметсодержащего сырья с получением на каждой стадии выщелачивания высококонцентрированных остаточных продуктов, в зависимости от технологической необходимости. Сущностью способа является постадийный перевод в раствор различных металлов с получением более обогащенного раствора по основному материалу (золото) на конечной стадии хлорирования, включающий сернокислотное выщелачивание с последующим сернокислотным окислительным выщелачиванием в присутствии аммиачной селитры с последующим переводом в раствор золота методом хлорирования в присутствии разбавленной серной кислоты, аммиачной селитры и поваренной соли, с последующим восстановлением золота из раствора. Способ позволяет проводить аффинаж без учёта начального состава перерабатываемого материала, содержащего драгметаллы, с последовательным выведением их в раствор. Обеспечивает снижение производственных затрат и экологической нагрузки, повышает эффективность извлечения конечного продукта.The invention relates to the metallurgy of noble metals, including gold, can be used in the processing of both low-grade and high-grade primary and secondary precious-containing raw materials with obtaining at each stage of leaching highly concentrated residual products, depending on the technological need. The essence of the method is a stepwise transfer to a solution of various metals with obtaining a more enriched solution on the base material (gold) at the final chlorination stage, including sulfuric acid leaching followed by sulfuric acid oxidative leaching in the presence of ammonium nitrate with subsequent conversion to gold solution by chlorination in the presence of dilute sulfuric acid , ammonium nitrate and salt, followed by recovery of gold from the solution. The method allows refining without taking into account the initial composition of the processed material containing precious metals, with their subsequent removal into solution. Provides a reduction in production costs and environmental stress, increases the efficiency of extraction of the final product.
