Основным методом исследования являлись минералогический анализ, электронно-зондовые и технологические исследования. Проведенным исследованием выявлены и охарактеризованы галогениды серебра, установлена их генетическая связь с золотом и обоснована роль гипергенных процессов в перераспределении золота. Золото-серебряное месторождение Архарлы (Казахстан) характеризуется сложным вещественным составом руд и разнообразием форм нахождения золота, существенно влияющих на эффективность их переработки. В работе рассмотрены фазовые формы золота в зоне окисления и их влияние на технологические показатели извлечения. На основе минералогических, электронно-зондовых и технологических исследований установлено, что золото представлено различными формами: самородным золотом разной пробности, электрумом, а также тонкодисперсными выделениями, ассоциированными с минералами серебра. Особое внимание уделено галогенидам серебра, широко развитым в зоне окисления и образующим сложные срастания с самородным серебром и золотом. Текстурно-структурные особенности минеральных агрегатов свидетельствуют о перераспределении золота в гипергенных условиях. Формирование золотоносных фаз связано с хлоридной и, вероятно, коллоидной миграцией вещества, что приводит к образованию зональных структур и включений высокопробного золота. Результаты технологических испытаний показали низкую эффективность гравитационного обогащения, обусловленную тонкодисперсным характером золота, и высокую эффективность цианирования и сорбционного выщелачивания (извлечение золота до 93,5%). Установлена прямая зависимость между фазовыми формами золота и показателями его извлечения. Полученные результаты расширяют представления о поведении золота в зоне окисления и могут быть использованы при разработке эффективных технологий переработки сложных золото-серебряных руд.</p></abstract><trans-abstract xml:lang="en"><p>The aim of this study is to determine the phase forms of gold in the oxidation zone of the Arkharly deposit and to assess their influence on the efficiency of gold and silver recovery. The main research methods included mineralogical analysis, electron microprobe studies, and technological testing. The study identified and characterized silver halides, established their genetic relationship with gold, and substantiated the role of supergene processes in the redistribution of gold. The Arkharly gold-silver deposit (Kazakhstan) is characterized by a complex composition of ores and a variety of gold occurrence forms, which significantly affect processing efficiency. This paper examines the phase forms of gold in the oxidation zone and their impact on technological recovery indicators. Based on mineralogical, electron microprobe, and technological studies, it was found that gold occurs in various forms: native gold of different fineness, electrum, as well as finely dispersed particles associated with silver minerals. Particular attention is given to silver halides, widely developed in the oxidation zone and forming complex intergrowths with native silver and gold. Textural and structural features of mineral aggregates indicate the redistribution of gold under supergene conditions. The formation of gold-bearing phases is associated with chloride and, presumably, colloidal migration of matter, leading to the formation of zonal structures and inclusions of high-fineness gold. Technological test results showed low efficiency of gravity concentration due to the fine-dispersed nature of gold, and high efficiency of cyanidation and sorption leaching (gold recovery up to 93.5%). A direct relationship between the phase forms of gold and recovery indicators has been established. The obtained results expand the understanding of gold behavior in the oxidation zone and can be used in developing effective technologies for processing complex gold-silver ores.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>месторождение Архарлы</kwd><kwd>золото</kwd><kwd>зона окисления</kwd><kwd>галогениды серебра</kwd><kwd>фазовые формы золота</kwd><kwd>гипергенные процессы</kwd><kwd>цианирование</kwd><kwd>сорбционное выщелачивание</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Arkharly deposit</kwd><kwd>gold</kwd><kwd>oxidation zone</kwd><kwd>silver halides</kwd><kwd>phase forms of gold</kwd><kwd>supergene processes</kwd><kwd>cyanidation</kwd><kwd>sorption leaching</kwd></kwd-group><funding-group xml:lang="en"><funding-statement>This research was funded by The Ministry of Science and Higher Education of the Republic of Kazakhstan, AP23487772 «Studying silver and gold halides in the Arkharly deposit (Jungar Alatau) for mining purposes»</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Hedenquist, J.W., Arribas, A., Gonzalez-Urien, E.
