Упорность к обогащению связана с тонкой вкрапленностью вплоть до микронной и тесным взаимопрорастанием рудных и породных минералов. Сульфиды железа представлены широким спектром минералов – пирит, марказит и их разновидность мельниковит, мышьяковистый пирит и арсенопирит; сажистый мельниковит обладает повышенной флотоактивностью. Уменьшение содержания сульфидов железа с 89 до 29 % сопровождается повышением доли легкофлотируемых породных минералов до 45 % и глины до 9 %, что относит их к труднообогатимым и сохраняет упорность руды к флотационному обогащению. Содержание сульфидов меди в пробах руды изменяется от 3,32 до 7,29 %; относительная доля сульфида меди в виде теннантита в разных пробах месторождения варьируется от 29 до 93 %; присутствует медь в виде халькопирита и борнита. Наилучшая флотоактивность теннантита наблюдается в нейтральной или слабокислой средах, в отличие от стандартного режима флотации халькопирита и борнита бутиловым ксантогенатом в высокощелочной известковой среде. Свободные зерна медных минералов могут быть селективно выделены в межцикловые медные концентраты при измельчении не более 60 % класса –71 мкм. Для упорной медьсодержащей руды с переменным содержанием теннантита разработана технология флотации в низкощелочной среде с использованием селективного сульфгидрильного собирателя М-ТФ в межцикловых медных флотациях и в цикле доводки медного концентрата; с аэрацией для подавления флотоактивности мельниковита, которая позволяет получать извлечение меди на уровне 80 % в кондиционный медный концентрат. Тонкая вкрапленность борнита, теннантита, халькопирита, сфалерита в пирите делает рациональным получение медно-пиритных, медно-цинково-пиритных продуктов с их выходом до 12 % для пиро-гидрометаллургической переработки, наряду с выделением богатых медных концентратов.</p></abstract><trans-abstract xml:lang="en"><p>The paper presents the results obtained when studying material compositions of four samples of refractory copper-bearing ores from the Uzelga deposit along with technological solutions to improve their processing parameters. The refractoriness of ores is associated with a thin dissemination (up to a micron size) and close intergrowth of ore and rock minerals. Ferrous sulfides are represented by a wide range of minerals: pyrite, marcasite and their variety melnikovite, arsenic pyrite and arsenopyrite; sooty melnikovite has a higher flotation activity. The reduction of iron sulfides from 89 to 29 % is followed by a proportional increase of easy-floatable rock minerals to 45 % and clay to 9 %. These properties make these sulfides difficult to process (float) and maintain ore refractoriness. The content of copper sulfides in ore samples varies from 3,32 to 7,29 %; the relative fraction of copper sulfide in a form of tennantite in different deposit samples varies from 29 to 93 %. Copper is also present as chalcopyrite and bornite. The best flotation activity of tennantite can be seen in neutral and weak acid media in contrast with standard flotation mode for chalcopyrite and bornite with butyl xanthate in a high-alkaline calcareous medium. Free grains of copper minerals can be selectively extracted into the intermediate flotation copper concentrates when grinding maximum 60 % of the –71-μm class. The technology of flotation in a low-alkaline medium is developed for refractory copper-bearing ores with variable tennantite content using the M-TF selective sulfhydryl collector in intermediate copper flotations and copper concentrate upgrading cycle; aeration used to suppress melnikovite flotation activity makes it possible to achieve 80 % copper recovery into conditioned copper concentrate. Bornite, tennantite, chalcopyrite and sphalerite disseminated in pyrite make it rational to obtain copper-pyrite, copper-zinc-pyrite products with their yield up to 12 % for pyroand hydrometallurgical processing.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>флотация</kwd><kwd>технология</kwd><kwd>теннантит</kwd><kwd>мельниковит</kwd><kwd>реагентный режим</kwd><kwd>аэрация</kwd></kwd-group><kwd-group xml:lang="en"><kwd>flotation</kwd><kwd>technology</kwd><kwd>tennantite</kwd><kwd>melnikovite</kwd><kwd>reagent regime</kwd><kwd>aeration</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">Petrus H.T.B.M., Hirajima T., Sasaki K., Okamoto H.
