На основе анализа литературных источников и практических данных определены причины образования металлургических отходов на территории РФ. Проанализированы исследования, ведущиеся в научных организациях. Установлено, что для переработки отходов перспективен глиноземсодержащий смет, образующийся в процессе производства алюминиевого сырца на электролизерах с самообжигающимися анодами при различных технологических операциях. Глиноземсодержащий смет представляет собой отходы сложного переменного состава, сметаемые в цехах электролиза. Выявлено что глиноземсодержащий смет состоит из криолита (Na3AlF6), хиолита (Al3F14Na5), корунда (Al2O3), сидерита (FeCo3), пирита (FeS2), кварца (SiO2), полевого шпата ((Ca, Na)(Al, Si) AlSi2O8), углеродистого вещества и техногенной фазы состава (NaF)•1,5CaF2•AlF3. Интерес к их переработке состоит в том, что в них содержится значительное количество ценных компонентов (Na3AlF6, Al2O3, AlF3), извлечение которых и повторное использование в получении алюминия могут способствовать снижению себестоимости единицы продукции. Проблемой является наличие в смете компонентов (SiO2, Fe2O3), которые при попадании в электролит оказывают негативное влияние на процесс электролиза. Результаты изучения химического состава монофракций позволили сделать вывод, что исключение темной (серовато-черной) массы, в которой содержание примесей (SiO2, Fe2O3) максимально, позволит в значительной степени решить поставленную задачу исследования. На основании выдвинутой гипотезы представлены результаты проведения воздушной классификации смета фракций 0—10 и 0—5 мм в каскадно-гравитационном (КГ) и центробежном (КЦ) классификаторах. По результатам выполненных исследований рекомендуется применять в схеме обогащения глиноземсодержащего смета алюминиевого производства воздушную классификацию в КГ смета фракции 0—10 мм.</p></abstract><trans-abstract xml:lang="en"><p>The article deals with the formation and processing of waste at aluminum production plants. Based on the analysis of literary sources and practical data, the reasons for the formation of metallurgical waste in the territory of the Russian Federation are established. The analysis of research conducted in scientific organizations is presented. It was found that one of the most promising for waste processing is alumina-containing sweepings formed during the production of liquid aluminum in Soderberg cells during various process operations. Alumina-containing sweepings are waste of complex variable composition swept away in electrolysis shops. It was found that alumina-containing sweepings consist of cryolite (Na3AlF6), chiolite (Al3F14Na5), corundum (Al2O3), siderite (FeCo3), pyrite (FeS2), quartz (SiO2), feldspar ((Ca, Na)(Al, Si) AlSi2O8), carbonaceous matter and (NaF)•1,5CaF2•AlF5 technogenic phase. Their processing is of interest due to the fact that they contain a significant amount of valuable components (Na3AlF6, Al2O3, AlF3) that can be extracted and reused in aluminum production to reduce the cost per unit. The problem is that sweepings contain components (SiO2, Fe2O3), which have a negative effect on the electrolysis process when in contact with electrolyte. The data obtained when studying the chemical composition of monofractions made it possible to conclude that the exclusion of the dark (grayish-black mass) with the maximum content of impurities (SiO2, Fe2O3) will substantially solve the stated problem of the study. Based on the hypothesis put forward, the paper presents the results of 0—10 mm and 0—5 mm sweepings air classification in cascade-gravity and centrifugal classifiers. Based on the studies conducted, we recommend using 0—10 mm sweepings air classification in the cascade gravity classifier in the processing flow of alumina-containing sweepings of aluminum production.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>производство алюминия</kwd><kwd>техногенное сырье</kwd><kwd>глиноземсодержащий смет</kwd><kwd>химический состав</kwd><kwd>примеси</kwd><kwd>очистка</kwd><kwd>минералогические исследования</kwd><kwd>электролиз</kwd><kwd>воздушная классификация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>aluminum production</kwd><kwd>technogenic raw materials</kwd><kwd>alumina-containing sweepings</kwd><kwd>chemical composition</kwd><kwd>impurities</kwd><kwd>purification</kwd><kwd>mineralogical research</kwd><kwd>electrolysis</kwd><kwd>air classification</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке гранта Президента Российской Федерации № МК-1739.2020.5.</funding-statement><funding-statement xml:lang="en">The research was supported by Grant № МК 1739.2020.5 of the President of the Russian Federation.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Barcelos D.A., Pontes F.V.M., Da Silva F.A.N.G., Castro D.C., Dos Anjos N.O.A., Castilhos Z.C.
