      <abstract xml:lang="ru">
        <p>Приведены результаты исследований по созданию технологий и оборудования в области рудоподготовки и пневматического сухого обогащения руд полезных ископаемых. Рассмотрены способы дробления и измельчения перед обогащением полезных ископаемых, исследовано сухое обогащение геоматериалов. Разработаны и апробированы высокоэффективные опытные образцы горно-обогатительного оборудования: дробилки многократного динамического воздействия РД-МДВ-900, ДКД-300, центробежные измельчители ЦМВУ-800 и ВЦИ-12, пневмосепаратор ПОС-2000. Созданы принципиальные конструкции и проектируется ряд новых аппаратов рудоподготовки и пневматического обогащения. Показана эффективность апробации автономного комплекса сухого обогащения с новыми безопасными стандартами экологии по переработке золотосодержащих руд, позволяющих полностью раскрыть и извлечь свободное золото крупностью от 10000 до 100 мкм. Внедрение сухого метода обогащения для горнодобывающей промышленности является весьма перспективным, позволит снизить капитальные затраты на строительство стационарных обогатительных фабрик, полностью или частично отказаться от применения технологической воды, строительства системы водоснабжения, традиционного хвостохранилища и т.д.</p>

        <p>The article presents the results of research on the development of processes and equipment for ore preparation and pneumatic dry beneficiation of mineral ores. The methods of crushing and grinding before enrichment of minerals have been considered, dry enrichment of geomaterials is investigated. Highly efficient prototypes of beneficiation equipment are developed and tested: crushers of multiple dynamic impact RD-MDV-900, DKD-300, centrifugal grinders CMVU-800 and VCI-12, pneumatic separator POS-2000. Fundamental designs are created, and a number of new ore preparation and pneumatic beneficiation instruments are being designed. The efficiency of approbation of an autonomous dry beneficiation complex with new safe environmental standards for the processing of gold-bearing ores, which makes it possible to fully release and extract free gold with a particle size from 10,000 to 100 µm, is shown. The introduction of the dry beneficiation method is very promising for the mining industry. It will allow to reduce capital costs for the construction of stationary beneficiation plants, completely or partially withdraw from the use of process water, the construction of a water supply system, a traditional tailing dam, etc.</p>
