Abstract

Изобретение относится к способу извлечения благородных металлов из отходов с низким содержанием регенируемых металлов. Способ включает нагрев отходов на основе нелетучих по отношению к извлекаемым металлам материалов с содержанием благородных металлов 0,001-30,0 мас.% при 950-2200°С в течение 1-10 ч в вакууме 10-10мм рт.ст. в химически инертных условиях, при этом происходит возгонка благородных металлов. Осуществление возгонки благородных металлов сразу из исходного сырья позволяет перерабатывать бедные отходы с высокой степенью извлечения ценных компонентов.The invention relates to a method for extracting precious metals from waste with a low content of recoverable metals. The method includes heating of waste materials based on non-volatile with respect to recoverable metals with a content of precious metals of 0.001-30.0 wt.% At 950-2200 ° C for 1-10 hours in a vacuum of 10-10 mm Hg. in chemically inert conditions, when this occurs the sublimation of noble metals. The implementation of the sublimation of precious metals directly from the feedstock allows you to recycle poor waste with a high degree of extraction of valuable components.
