Термодинамические расчеты и экспериментальные исследования по обогащению полиметаллического марганецсодержащего сырья позволили определить основные технологические параметры извлечения компонентов и разработать технологическую схему обогащения. По предложенной технологической схеме возможно получение высококачественных концентратов марганца, никеля, железа, кобальта. Применение оптимальных технологических параметров обогащения позволяет из полиметаллического марганецсодержащего сырья извлекать до 95 – 97 % Mn, 98 – 99 % Ni, 96 – 98 % Fe, 60 % Co. Показано, что марганцевый концентрат целесообразно использовать для выплавки марганца металлического и сталей с низким содержанием фосфора, что позволит снизить зависимость от импорта марганецсодержащих материалов. Разработана технология легирования стали с использованием полученного концентрата никеля, при этом замена никеля металлического его концентратом значительно сократит расходы на легирование. Разработана технология получения металлизованного железа методом твердофазного восстановления из железного концентрата, что позволит снизить содержание вредных примесей в стали.</p></abstract><trans-abstract xml:lang="en"><p>Manganese ores are detected in the Altai – Sayan metallogeniczone, they can be referred to the polymetallic ores, but theycannot be used for standard alloys production without preliminarydressing as they have a high content of phosphorus and iron. Thermodynamic calculations and experimental investigations on polymetallic manganese raw material dressing have determined some basic technological parameters of recovering and technologicaldiagram of dressing. Obtaining of high- quality concentrates of manganese, nickel, iron, cobalt is possible due to that technological diagram. The application of optimal technological parameters of dressing can retrieve up to 95 – 97 % of manganese, 98 – 99 % of nickel and 96 – 98 % of iron from polymetallic manganesecontaining raw material. It has been demonstrated that manganese concentrate can be used for manganese smelting and for  teels with low content of phosphorus, and that allows reducing import of manganese materials. The technology of steel alloying with the usage of the obtained nickel concentrate has been worked out; and when metallic nickel is substituted by nickel concentrate, the costs for alloying are reduced considerably. The technology ofmetalized iron obtaining by the method of solid-phase recovery and iron concentrate has been worked out, and it can allow decreasing harmful impurities in steel.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>полиметаллические марганецсодержащие руды</kwd><kwd>высококачественный марганцевый концентрат</kwd><kwd>никелевый концентрат</kwd><kwd>металлизованный продукт</kwd><kwd>обогащение</kwd><kwd>марганец металлический</kwd><kwd>прямое легирование</kwd><kwd>стали</kwd></kwd-group><kwd-group xml:lang="en"><kwd>polymetallic manganese ores</kwd><kwd>high- quality manganese concentrate</kwd><kwd>nickel concentrate</kwd><kwd>metalized product</kwd><kwd>dressing</kwd><kwd>metallic manganese</kwd><kwd>direct alloying</kwd><kwd>steel</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">Polulyakh L.A., Dashevskii V.Ya., Yusfin Yu.S.
