        <p>Работа посвящена сравнительному обзору минерально-сырьевой базы металлов платиновой группы (МПГ) и технологий их переработки в ЮАР и России – крупнейших производителей МПГ. В статье представлены минералого-геохимическая классификация и промышленное значение железно-платиновых и платиноносных месторождений, также представлен обзор видов залеганий рудных тел металлов платиновой группы, процессов обогащения (особое внимание уделено флотационным процессам), а также трудностей, с которыми сталкиваются предприятия на этапе обогащения в части повышения извлечения полезных компонентов. Приведены данные о минералогических особенностях месторождений МПГ, в том числе о распределении элементов в рудах. Определены и обоснованы основные направления исследования минералогических особенностей и переработки сырья различного генезиса. Установлено, что сульфидные месторождения представляют наибольшую промышленную ценность в обеих странах. Рассмотрены такие нетрадиционные источники МПГ как черносланцевое сырье, дуниты, хромитовые, малосульфидные, хромовые и титано-магнетитовые руды, техногенное сырье и др. Обоснованы основные направления исследований для вовлечения в переработку нетрадиционных источников металлов. Проведен анализ новых обогатительных и металлургических методов добычи МПГ при переработке нетрадиционного и промышленного сырья, выполнен обзор существующих технологий переработки платиноносного сырья. Рассмотрены технологии с применением современного оборудования для сверхтонкого измельчения и существующие реагенты для флотационного обогащения и оценки их селективности по отношению к минералам-концентраторам платины. На основе анализа главных технологических процессов переработки руд МПГ выявлены наиболее эффективные – схемы гравитационно-флотационного обогащения с последующей металлургической переработкой.</p>

      <abstract xml:lang="en">
        <p>The presented study is devoted to a comparative review of the mineral raw material base of platinum group metals (PGMs) and technologies of their processing in South Africa and Russia, the largest PGM producers. Mineralogical and geochemical classification and industrial value of iron-platinum and platinum-bearing deposits are presented in this work. The paper also reviews types of PGM ore body occurrences, ore processing methods (with a special focus on flotation processes), as well as difficulties encountered by enterprises at the processing stage, as they increase recovery of the valuable components. Data on mineralogical features of PGM deposits, including the distribution of elements in the ores, are provided. The main lines of research on mineralogical features and processing of raw materials of various genesis are identified and validated. Sulfide deposits are found to be of the highest industrial value in both countries. Such unconventional PGM sources, as black shale, dunites, chromite, low-sulfide, chromium and titanomagnetite ores, anthropogenic raw materials, etc. are considered. The main lines of research that would bring into processing non-conventional metal sources are substantiated. Analysis of new processing and metallurgical methods of PGM recovery from non-conventional and industrial raw materials is conducted; the review of existing processing technologies for platinum-bearing raw materials is carried out. Technologies that utilize modern equipment for ultrafine grinding are considered, as well as existing reagents for flotation recovery; evaluation of their selectivity in relation to platinum minerals is presented. Basing on the analysis of main technological processes of PGM ore treatment, the most efficient schemes are identified, i.e.,gravity and flotation treatment with subsequent metallurgical processing.</p>
