Анализ существующих технологий переработки высокомышьяковистого медного сырья, которые базируются преимущественно на применении гидрометаллургических методов, проводился на основе обзора отечественной и зарубежной научной литературы. Показано, что применение гидрометаллургических способов переработки позволяет перевести опасные для окружающей среды компоненты продуктов переработки в инертные твердые отходы, избегая образования газообразных выбросов. Проведенный литературный анализ позволил подробно рассмотреть способы утилизации мышьяка из технологического процесса переработки сырья. Установлено, что это – методы окисления и осаждения мышьяка в виде малорастворимых и устойчивых соединений. Рассмотрены методы окисления мышьяка, подразумевающие использование таких веществ, как кислород, пероксид водорода, озон, смесь кислорода и диоксида серы, гипохлорит натрия. Проанализированы способы, в которых окисление осуществляется посредством ионов железа и перманганата, бактерий (биоокисление), а также за счет введения катализатора процесса – активированного угля. Показано, что основными методами осаждения являются нейтрализация известью, осаждение сульфидов, соосаждение мышьяка с помощью ионов железа, осаждение скородита, технология инкапсуляции. В результате анализа рассмотренных способов намечены перспективные пути решения проблемы переработки высокомышьяковистых медных концентратов, которая связана с экологическими требованиями к выбросам мышьяка в окружающую среду: комплексная переработка данного типа сырья при помощи автоклавного окисления. Данный способ позволит не только эффективно осаждать мышьяк в виде малотоксичного соединения – скородита, но и выделить ценные компоненты (медь, золото, серебро) с их последующим извлечением в самостоятельные готовые продукты. Полученные результаты позволили задать направление для дальнейшего углубленного изучения проблемы.</p></abstract><trans-abstract xml:lang="en"><p>Methods presented in Russian and foreign scientific literature sources for processing high-arsenic copper raw materials to convert arsenic into low-soluble and stable compounds are reviewed. Hydrometallurgical processing methods are shown to be applicable for converting environmentally hazardous components into inert solid wastes while avoiding the formation of gaseous emissions. The isolation of arsenic when processing raw materials involves its oxidation and precipitation in the form of low-soluble and stable compounds. Methods for arsenic oxidation using oxygen, hydrogen peroxide, ozone, mixture of oxygen and sulphur dioxide, sodium hypochlorite are compared. Methods of oxidation by iron and permanganate ions, bacteria (biooxidation), as well as by introducing an activated carbon catalyst, are also considered. Precipitation approaches include neutralization by lime, precipitation of sulphides, co-precipitation of arsenic with iron ions, precipitation of scorodite, and encapsulation technology. As a result of the performed analysis, the authors present a promising approach for solving the problem of processing high-arsenic copper concentrates to comply with standards governing arsenic emissions into the environment, including the comprehensive processing of these raw materials using autoclave oxidation. In addition to the ensuring effective precipitation of arsenic in the form of a low-toxic compound (scorodite), this method can be used to isolate valuable components (copper, gold, silver) with their subsequent extraction into individual finished products. The obtained results establish a direction for a further in-depth study of the problem.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>мышьяк</kwd><kwd>медные концентраты</kwd><kwd>окисление мышьяка</kwd><kwd>осаждение мышьяка</kwd><kwd>комплексная переработка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>arsenic</kwd><kwd>copper concentrates</kwd><kwd>arsenic oxidation</kwd><kwd>arsenic precipitation</kwd><kwd>complex processing</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">Зайцев П.
