Существуют различные технологии переработки пиритовых концентратов, содержащих драгоценные и цветные металлы, Au, Ag, Cu, а также другие элементы. Эти технологии часто имеют такие недостатки, как нежелательное выделение диоксида серы в окружающую среду, неполная экстракция полезных металлов. Приведены оптимальные режимы проведения технологических процессов, таких как температура обжига, соотношение паровой и твердой фаз, длительность процесса, размеры частиц и др. Особое внимание уделялось десульфуризации пиритного концентрата с предотвращением выделения сернистого ангидрида в атмосферу и с переводом его в фазу твердой элементарной серы или сульфида натрия. Разработанная технология позволяет получить железный огарок, и с последующей магнитной сепарацией и восстановлением в атмосфере водорода получить железо в виде губки – высококачественного продукта для выплавки сталей или чугунов. Предлагаемая технология обеспечивает замкнутый цикл и безотходность с минимальным загрязнением окружающей среды. Технология испытана в пилотной лабораторной установке с использованием концентратов пирита Каджаранского месторождения Армении.</p></abstract><trans-abstract xml:lang="en"><p>The paper discusses the benefits of processing pyrite concentrates using a new technology that uses roasting in an atmosphere of water vapor. There are various technologies for the processing of pyrite concentrates containing precious and non-ferrous metals, Au, Ag, Cu and other elements. These technologies often have such disadvantages as undesirable release of sulfur dioxide into the environment, incomplete extraction of useful metals. The optimal modes of technological processes, such as firing temperature, the ratio of steam and solid phases, the duration of the process, the size of the particles, etc. are given. Special attention was paid to the desulfurization of pyrite concentrate with the prevention of the release of sulfur dioxide into the atmosphere, and its transfer into the phase of solid elemental sulfur or sodium sulfide. The developed technology makes it possible to obtain an iron cinder, and with subsequent magnetic separation and reduction in a hydrogen atmosphere to obtain iron in the form of a sponge–a high-quality product for smelting steel or cast iron. The proposed technology provides a closed loop cycle and waste-free with minimal environmental pollution. The technology was tested in a pilot laboratory setup using concentrates from the Kajaran deposit inArmenia.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>концентрат пирита</kwd><kwd>парооксидирование</kwd><kwd>десульфуризация</kwd><kwd>чистое железо</kwd></kwd-group><kwd-group xml:lang="en"><kwd>pyrite concentrate</kwd><kwd>steam oxidation</kwd><kwd>desulfurization</kwd><kwd>pure iron</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">World – Pyrites – Market Analysis, Forecast, Size, Trends and Insights [Электронный ресурс].
