Обычно цинк и свинец восстанавливают из их оксидов углеродом (расход углерода составляет в среднем 500 кг/т пыли). Результаты термодинамических расчетов и экспериментальных исследований показали, что эти металлы могут быть извлечены из пыли без участия углерода или при его малом содержании (менее 3 %). Для извлечения свинца требуется температура порядка 1400 К, а для цинка – 2000 К. Температуры их извлечения зависят от состава пыли, в частности, от содержания углерода, хлора и соотношения О/С. Они могут зависеть также от фазового и дисперсного состава пыли. Проведен физико-химический анализ процессов пылеобразования в дуговых сталеплавильных печах (ДСП), изучены состав и свойства пыли, проведены экспериментальные исследования процесса селективного извлечения цинка и свинца в лабораторных условиях. Разработана технология переработки пыли и оценен возможный инновационный потенциал ожидаемых результатов. Предлагаемые подходы базируются на исследовании непрерывного двухстадийного процесса безуглеродного и селективного извлечения цинка и свинца из пыли ДСП разного состава. Одним из главных результатов работы, наряду с созданием технологии, обеспечивающей селективное извлечение цинка и свинца до 99 %, является разработка процесса обезвреживания пыли от ДиФ до экологически безопасного уровня.</p></abstract><trans-abstract xml:lang="en"><p>In electric-arc furnace dust zinc content can reach 43 %, lead content can reach 4 %. The content of ecotoxicants such as dioxins and furans (D&amp;F) adsorbed on dust particles achieve 500 ng/kg of dust. Generally, zinc and lead are reduced from their oxides by dint of carbon (an average of 500 kg/t dust). The results of thermodynamic calculations and experimental studies have shown that these metals can be extracted from dust without the participation of carbon or at its low content (less than 3 %) [<xref ref-type="bibr" rid="cit1">1</xref>]. Temperature of about 1400 K is required to extract lead, and about 2000 K is required for zinc extraction. The temperatures of their extraction depend on the dust composition, in particular, on the content of carbon, chlorine and the O/C ratio [<xref ref-type="bibr" rid="cit2">2</xref>]. They can also depend on phase and dispersed composition of the dust. A physicochemical analysis of the dust formation processes in electric arc furnaces (EAF) has been carried out, the composition and properties of dust have been investigated, and experimental studies of the zinc and lead selective extraction process in laboratory conditions have been leaded. A dust processing technology has been developed and the possible innovative potential of the expected results has been assessed. The approaches we propose are based on the study of a continuous two-stage process of carbon-free and zinc and lead selective extraction from EAF dust of different composition. One of the main results of the work, along with the creation of a technology that ensures the selective zinc and lead extraction up to 99 %, is the development of a process for neutralizing EAF dust from D&amp;F to an environmentally safe level.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>черная металлургия</kwd><kwd>цветные металлы</kwd><kwd>сталеплавильная пыль</kwd><kwd>пыль ДСП</kwd><kwd>безуглеродный процесс</kwd><kwd>селективное извлечение</kwd><kwd>испарение</kwd><kwd>цинк</kwd><kwd>свинец</kwd><kwd>железо</kwd><kwd>вторичные ресурсы</kwd><kwd>ресурсосбережение</kwd><kwd>загрязнители</kwd><kwd>класс опасности</kwd><kwd>экологическая безопасность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ferrous metallurgy</kwd><kwd>non-ferrous metals</kwd><kwd>steel dust</kwd><kwd>electric-arc furnace dust (EAF dust</kwd><kwd>EAFD)</kwd><kwd>carbon-free process</kwd><kwd>selective extraction</kwd><kwd>evaporation</kwd><kwd>zinc</kwd><kwd>lead</kwd><kwd>iron</kwd><kwd>secondary resources</kwd><kwd>resource saving</kwd><kwd>pollutants</kwd><kwd>hazard class</kwd><kwd>environmental safety</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена при поддержке Фонда содействия инновациям в рамках программы «УМНИК», договор № 12699ГУ/2017.</funding-statement><funding-statement xml:lang="en">The work was financially supported by the Fund for the Promotion of Innovations within the framework of the program “UMNIK”, contract No. 12699GU/2017.</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">Патрушов А.Е.
