Поэтому приоритетной задачей для исследователей является разработка технологических приемов, позволяющих не только концентрировать целевые металлы в обогащенные продукты, но и извлекать ранее теряемые со шлаками и пылями ценные элементы-примеси. Одним из способов ее решения является создание технологических схем, сочетающих гидрометаллургические и обогатительные операции. Ранее проведенными исследованиями была показана эффективность применения автоклавных процессов и флотации для обезмеживания медеэлектролитного шлама и его обогащения по золоту, серебру и селену. Однако применение автоклавных процессов требует больших капитальных и текущих затрат. Поэтому был проведен цикл экспериментов по аэрационному обезмеживанию шлама с последующей флотацией и получены соответствующие результаты опытов. В настоящей работе было изучено влияние условий аэрационного выщелачивания (температуры, условий перемешивания, удельного расхода окислителя – воздуха и кислорода), дезинтеграции полученного продукта, а также параметров флотации на селективность разделения оксидной и халькогенидной фаз и качество получаемых при этом концентратов. По результатам экспериментов разработаны технологические операции, позволяющие обогащать медеэлектролитные шламы в 2–3 раза по содержанию драгоценных металлов без использования автоклавных процессов. Определены условия и аппаратурное оформление для глубокого обезмеживания шлама (менее 0,5–0,8 % остаточного содержания меди). Достигнут приемлемый уровень разделения халькогенидов драгоценных металлов и оксидных соединений свинца и сурьмы, что позволит в дальнейшем извлекать при переработке соответствующих концентратов товарные продукты. Приведены результаты анализа получаемых продуктов с использованием методов РЭМ и РСМА. Полученные данные являются вкладом в создание комплексной гидрометаллургической технологии переработки анодных шламов медного производства.</p></abstract><trans-abstract xml:lang="en"><p>With the declining quality of feedstock in the copper industry, maintaining metal recovery rates and controlling production costs for non-ferrous and precious metals has become increasingly critical. A key research priority is therefore the development of processing strategies that not only concentrate target metals into flotation products but also recover valuable minor elements previously lost with slags and flue dust. One approach involves designing process flowsheets that integrate hydrometallurgical and beneficiation operations. Previous studies have demonstrated the effectiveness of combining autoclave leaching and flotation for decopperization of copper anode slimes and their concentration in gold, silver, and selenium. However, autoclave leaching requires significant capital and operating expenditures. For this reason, a series of tests was carried out on aeration leaching (decopperization) of copper anode slimes followed by flotation, yielding promising results. This study examined the influence of aeration leaching conditions (temperature, agitation, and specific oxidant consumption—air and oxygen), disintegration of the leached product, and flotation parameters on the selective separation of oxide and chalcogenide phases and the quality of the resulting concentrates. Based on the experimental results, process operations were developed that make it possible to concentrate precious metals in copper anode slimes two- to threefold without the use of autoclave leaching. Optimal conditions and equipment configurations were determined for deep decopperization of slimes (to less than 0.5–0.8 % residual copper). An acceptable degree of separation of precious-metal chalcogenides from lead and antimony oxides was achieved, enabling downstream recovery of marketable products from the respective concentrates. Analytical characterization of the products was performed using scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). The findings contribute to the development of an integrated hydrometallurgical technology for processing copper anode slimes.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>медеэлектролитный шлам</kwd><kwd>аэрационное обезмеживание</kwd><kwd>флотационное обогащение</kwd><kwd>концентрат</kwd><kwd>хвосты флотации</kwd><kwd>драгоценные металлы</kwd><kwd>серебро</kwd><kwd>селен</kwd><kwd>теллур</kwd><kwd>свинец</kwd></kwd-group><kwd-group xml:lang="en"><kwd>copper anode slimes</kwd><kwd>aeration leaching (decopperization)</kwd><kwd>flotation processing</kwd><kwd>bulk concentrate</kwd><kwd>final tails</kwd><kwd>precious metals</kwd><kwd>silver</kwd><kwd>selenium</kwd><kwd>tellurium</kwd><kwd>lead</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Hait J., Jana R.K., Sanyal S.K.
