Основная (98,5 млн т (64,2 %)) часть балансовых запасов марганцевых руд сосредоточена на крупном Усинском месторождении в Кемеровской области. Кроме Усинского в Кемеровской области разрабатываются Кайгадатское (32,7 млн т), Дурновское (300 тыс. т), Селезеньское месторождения и участок Чумай. Для комплексного подхода к решению рассматриваемой проблемы необходимо технически и экономически обосновать все этапы (разведку месторождений, добычу и обогащение марганцевых руд, последующую их переработку и потребление) вовлечения в производство марганцевых руд месторождений Кемеровской области – Кузбасса. Высококачественные марганцевые концентраты по разработанной технологии кальций-хлоридного обогащения получают из карбонатных, в том числе высокофосфористых руд Усинского месторождения, бедных оксидных и железомарганцевых руд Селезеньского и Дурновского месторождений. Извлечение марганца из марганецсодержащего сырья в концентрат составляет не менее 90 %. Полученный концентрат содержит 58 – 64 % марганца, менее 0,01 % фосфора, 0,02 – 0,05 % оксида железа, 0,5 – 1,0 % кремнезема и следы серы. Термодинамические расчеты и экспериментальные исследования по обогащению полиметаллических марганецсодержащих руд участка Чумай позволили определить основные технологические параметры извлечения ценных компонентов. Применение оптимальных технологических параметров обогащения позволяет извлекать из сырья до 95 – 97 % марганца и 98 – 99 % никеля.</p></abstract><trans-abstract xml:lang="en"><p>Manganese ores of the vast majority of domestic deposits are of low quality: with low content of manganese (18 – 24 %) and high specific content of phosphorus (ratio P/Mn &gt; 0.006). They have an increased content of iron and silicon and they are difficult to enrich. The main part of balance reserves of manganese ores – 98.5 million tons (64.2 %) is concentrated in large Usinskoye field in the Kemerovo region. In addition to Usinskoye, there are also deposits in this region Kaigadatskoye (32.7 million tons), Durnovskoye (300 thousand tons), Selezenskoye fields and the Chumay plot. For a comprehensive approach to solving the proposed problem it is needed to assess technical and economic feasibility of all stages (exploration, extraction and enrichment of manganese ores, their subsequent processing and consumption) of involvement of manganese ores from these deposits in production. Using developed technology of calcium-chloride enrichment, high-quality manganese concentrates are obtained from carbonate, including high-phosphorous ores of the Usinskoye field, poor oxide and ferromanganese ores of the Selezenskoye and the Durnovskoye fields. Extraction of manganese from manganese-containing raw materials into concentrate was at least 90 %. The resulting concentrate contains 58 – 64 % of manganese, less than 0.01 % of phosphorus, 0.02 – 0.05 % of iron oxide, 0.5 – 1.0 % of silica and sulfur. Thermodynamic calculations and experimental studies on the enrichment of polymetallic manganese-containing ores from the Chumay plot allowed us to determine the main technological parameters for extracting valuable components. The use of optimal technological parameters of enrichment allows extraction of up to 95 – 97 % of manganese and 98 – 99 % of nickel from raw materials.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>марганцевые руды</kwd><kwd>концентрат химического обогащения</kwd><kwd>кальций-хлоридный способ обогащения</kwd><kwd>полиметаллические марганцевые руды</kwd><kwd>термодинамические расчеты</kwd><kwd>никелевый концентрат</kwd><kwd>железный концентрат</kwd></kwd-group><kwd-group xml:lang="en"><kwd>manganese ores</kwd><kwd>concentrate of chemical enrichment</kwd><kwd>calcium-chloride enrichment method</kwd><kwd>polymetallic manganese ores</kwd><kwd>thermodynamic calculations</kwd><kwd>nickel concentrate</kwd><kwd>iron concentrate</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке РФФИ и Субъекта РФ (Кемеровская область – Кузбасс) в рамках научного проекта № 20-48-420001/20.</funding-statement><funding-statement xml:lang="en">The study was financially supported by the RFBR and the R sian Federation region (Kemerovo Region – Kuzbass) within the framework of the scientific project No. 20-48-420001/20.</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">Литвинцева Э.Г., Тигунов Л.П., Броницкая Е.С. и др.
