Cфалерит является широко распространенным минералом, который может встречаться в месторождениях различного типа, где накапливает ценные примеси. В числе этих примесей наиболее ценной является золото. Вопрос о форме нахождения Au в сфалерите является дискуссионным.</p></sec><sec><title>Методы</title><p>Методы. В данной работе с использованием методов газового транспорта и солевого расплава были синтезированы серии образцов In-, Fe- и InFe-сфалерита. Опыты выполнены при ≈800°С c присутствием в системе металлического золота. Продукты синтеза были изучены методами РСМА и ЛА-ИСП-МС.</p></sec><sec><title>Результаты</title><p>Результаты. Кристаллы сфалерита содержали от 0 до 2.5 мол. % In и от 0 до 40 мол. % FeS. Все примесные элементы равномерно распределены в полученных кристаллах. После закалки сфалерит сохранял золото в “невидимой” форме. Наши данные доказывают, что наблюдающееся значительное увеличение концентрации Au в сфалерите прямо связано с присутствием в нем In (до 1.02 мас. % Au) и в меньшей степени Fe (до ≈600 г/т Au). Эти элементы замещают Zn в его кристаллической структуре в соответствии со схемами: Au+ + In3+ ↔ 2 Zn2+ или Au+ + Fe3+ ↔ 2 Zn2+, что согласуется с результатами исследования синтезированных фаз с помощью метода рентгеновской спектроскопии поглощения.</p></sec><sec><title>Результаты</title><p>Результаты. Более высокая фугитивность серы в системе, при наличии In, приводит к значительному увеличению степени вхождения золота в сульфид цинка. Концентрация Au, равномерно рассеянного в кристаллах сфалерита без прочих примесей, не превышает 10 г/т для данных условий синтеза и не зависит от фугитивности серы в системе.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Research subject</title><p>Research subject. Sphalerite (ZnS) is a widespread mineral that can be found in various depositional environments. During formation, this mineral can accumulate minor and trace impurities, with gold being one of the most valuable component. The issue of the chemical state of Au in sphalerite has been much discussed recently.</p></sec><sec><title>Methods</title><p>Methods. Samples of In-, Fe- and In-Febearing sphalerite with a composition ranging from 0 to 2.5 mol.% In2S3 and 0 – 40 mol.% FeS were synthesized in an Ausaturated system using gas transport and salt flux techniques. The resulting products were subsequently investigated using EPMA and LA-ICP-MS. Results. All the elements under investigation are found to be homogeneously distributed within the sphalerite matrix. After quenching, sphalerite is shown to retain Au. Our data indicates that the observed increase in Au concentration is caused by the presence of In (up to 1.02 wt % Au) and, to a lesser extent, by that of Fe (up to ≈600 ppm Au). These elements substitute Zn in the crystal structure of sphalerite following the scheme Au+ + In3+(Fe3+) ↔ 2Zn2+, which is in good agreement with previous data obtained using the XAS method.</p></sec><sec><title>Conclusions</title><p>Conclusions.A higher sulphur fugacity in the system leads to a more significant accumulation of Au in sphalerite. The concentration of Au in pure sphalerite does not exceed 10 ppm under our experimental conditions and does not depend on the activity of sulphur in the system.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>ЛА-ИСП-МС</kwd><kwd>РСМА</kwd><kwd>сфалерит</kwd><kwd>газовый транспорт</kwd><kwd>раствор-расплавный метод</kwd><kwd>золото</kwd><kwd>индий</kwd><kwd>изоморфизм</kwd><kwd>твердый раствор</kwd><kwd>примесь</kwd><kwd>фугитивность серы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>LA-ICP-MS</kwd><kwd>EPMA</kwd><kwd>sphalerite</kwd><kwd>gas transport method</kwd><kwd>salt flux method</kwd><kwd>gold</kwd><kwd>indium</kwd><kwd>admixture</kwd><kwd>solid solution</kwd><kwd>fugacity of sulphur</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">Бортников Н.С., Кабри Л., Викентьев И.В., Мак Мэйхон Г., Богданов Ю.А.
