In order to increase gold recovery, a hypothesis about effective (peroxide) preparation of refractory raw materials in the process of leaching has been described. The author focuses on theoretical justification of the physicalchemical model and the two-stage mechanism of oxidation (photoelectrochemical and bacterial) of material using microorganisms Acidithiobacillus ferrooxidans and Acidithiobacillus thiooxidans. A scheme of two-staged (physicochemical and bacterial) oxidation was developed. It is based on photoelectrochemical effects for the leaching of gold from refractory materials. It is shown that photoelectrochemical pre-oxidation makes it possible to increase development of the mineral matrix with its further bacterial oxidation. It also helps to increase the efficiency of invisible gold extraction from sulfide ores. Laboratory tests have been performed on the combined oxidation scheme on electroactivation carbon-in-leach of invisible gold from the Kokpatas deposit’s sulfide ores. The authors present the results of the laboratory tests of the activation methods for impacting upon the refractory ores before metal leaching, which prove the efficiency of such non-traditional methods for developing mineral matrix. Gold extraction using the combined technology of sulfide and arsenopyrite oxidation increases by 18%.</p></abstract><trans-abstract xml:lang="ru"><p>Рассмотрены причины упорности сульфидных руд с ультрадисперсными включениями золота. В целях повышения извлечения золота высказана гипотеза эффективной подготовки (пероксидной) труднообогатимого сырья к процессу выщелачивания. Дано теоретическое обоснование физико-химической модели и механизма двухстадиального окисления (фотоэлектрохимического и бактериального) материала с применением микроорганизмов Acidithiobacillus ferrooxidans и Acidithiobacillus thiooxidans. Разработана схема двухстадиального окисления (физико-химического и бактериального) на основе направленных фотоэлектрохимических воздействий для выщелачивания золота из упорного сырья. Показано, что предварительное фотоэлектрохимическое окисление позволяет повысить полноту вскрытия минеральной матрицы при последующем бактериальном ее окислении и повысить показатели извлечения дисперсного золота из сульфидных руд. Выполнены лабораторные исследования комбинированной схемы окисления электроактивационного сорбционного выщелачивания дисперсного золота из сульфидных руд месторождения Кокпатас. Приведены результаты лабораторных исследований активационных методов воздействия на упорное сырье перед выщелачиванием металла, которые доказывают эффективность предложенных нетрадиционных методов вскрытия минеральной матрицы. Увеличение извлечения золота после комбинированной технологии окисления сульфидов и арсенопирита составило 18%.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>упорные руды</kwd><kwd>пирит</kwd><kwd>арсенопирит</kwd><kwd>дисперсное золото</kwd><kwd>физико- химическое и бактериальное окисление</kwd><kwd>полиреагентные схемы</kwd><kwd>активные формы кислорода</kwd><kwd>электрохимические и фотохимические процессы</kwd></kwd-group><kwd-group xml:lang="en"><kwd>refractory ores</kwd><kwd>pyrite</kwd><kwd>arsenopyrite</kwd><kwd>invisible gold</kwd><kwd>physical and chemical oxidation and bacterial oxidation</kwd><kwd>polyreagent schemes</kwd><kwd>reactive oxygen</kwd><kwd>electrochemical and photochemical processes</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">Van Aswegen P.S.; Marais М.J., Haines А.
