The paper presents experimental studies on preliminary dry separation of Arkachan deposit ores to determine the quality of beneficiation of the separation products. The studies on dressability were carried out on pilot plants for dry ore processing and beneficiation: combined impact crusher DKD-300, centrifugal mill TsMVU-800, pneumatic separator POS-2000. Processing of the obtained separation products by pneumatic separation and screening according to the sequential flow chart of crushing and grinding was carried out in laboratory conditions at a gravity concentration table SKO-0.5. The GRG test was performed at an ITOMAK-0.1 centrifugal concentrator using a sequential grinding circuit. The GRG test showed that for more efficient gravity separation of gold, up to total gold recovery of 73.91%, the degree of grinding up to 80% passing 0.071 mm was required, allowing obtaining a gravity concentrate graded at 70.28 g/t gold.</p></abstract><trans-abstract xml:lang="ru"><p>Использование сухих технологий переработки и обогащения минерального сырья является одним из перспективных направлений, так как данный способ производства концентрата менее энергозатратен, менее трудоемок и экономически выгоден. В работе приведены экспериментальные работы по предварительному сухому обогащению руд месторождения Аркачан для определения качества обогащения продуктов разделения. Исследования на обогатимость проводились на опытных установках сухого метода переработки и обогащения руд: дробилке комбинированного ударного действия ДКД-300, центробежной мельнице ЦМВУ-800, пневмосепараторе ПОС-2000. Обработка полученных продуктов разделения пневмосепарацией и грохочением по последовательной схеме дробления и измельчения проводилась в лабораторных условиях на гравитационном концентрационном столе СКО-0,5. GRG-тест проходил на центробежном концентраторе ИТОМАК-0,1 по последовательной схеме измельчения. Анализ проведённого GRG-теста показал, что для более приемлемых условий гравитационного обогащения золота – до 73,91 % – необходима степень измельчения до 80 % класса −0,071 мм для получения гравитационного концентрата с содержанием 70,28 г/т золота.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>дробилка</kwd><kwd>мельница</kwd><kwd>пневмосепаратор</kwd><kwd>сухое обогащение</kwd><kwd>классификация</kwd><kwd>измельчение</kwd><kwd>концентратор</kwd><kwd>золото</kwd><kwd>извлечение</kwd><kwd>эффективность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>crusher</kwd><kwd>mill</kwd><kwd>pneumatic separator</kwd><kwd>dry separation</kwd><kwd>screening</kwd><kwd>grinding</kwd><kwd>concentrator</kwd><kwd>gold</kwd><kwd>recovery</kwd><kwd>performance</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Работа выполнена в рамках государственного задания Министерства науки и высшего образования Российской Федерации (тема № 0297-2021-0022, ЕГИСУ НИОКТР № 122011800089-2) с использованием оборудования ЦКП ФИЦ ЯНЦ СО РАН (грант №13.ЦКП.21.0016).</funding-statement></funding-group><funding-group xml:lang="en"><funding-statement>The study was performed within the framework of the state assignment of the Ministry of Science and Higher Education of the Russian Federation (Project No. 0297-2021-0022, EGISU Research and Development Center No. 122011800089-2) with the use of the equipment of the TsKP of the FRC YaSC SB RAS (grant No. 13.TsKP.21.0016).</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">Юсупов Т.
