Подземное выщелачивание урана является перспективным геотехнологическим процессом, обеспечивающим кардинальное повышение технической, экономической эффективности и экологической безопасности освоения урановых месторождений. В статье рассмотрены основные разработки МГРИ в этой области.</p></sec><sec><title>Цель</title><p>Цель. Исследовать процессы активационного выщелачивания урана рабочими растворами, прошедшими электрофотохимическую обработку до контактирования с рудой.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. Активационная подготовка выщелачивающих растворов обеспечивает возможность синтеза активных гидратированных форм кислорода и водорода с коллективизированными протонами и гидроксил-ионами, кластеризованными молекулами воды. После предокисления активным карбонатным раствором проведено модельное скважинное выщелачивание хлоридно-гипохлоритным, содовым, сернокислотным растворами. Тестирующее перколяционное выщелачивание урана из руд месторождений Учкудук и Сугралы активированными растворами, проведенное на стендах, конструкция которых разработана в МГРИ совместно с сотрудниками ИГД ДВО РАН и ЗабГУ, подтвердило потенциальную возможность существенного повышения коэффициента извлечения урана.</p></sec><sec><title>Результаты</title><p>Результаты. При выщелачивании растворами карбоната натрия и карбоната аммония извлечение урана из проб руды месторождения Сугралы составило 52 и 59% соответственно. В то же время использование активированного раствора перкарбоната натрия, совмещающего функцию окислителя и комплексообразователя, позволило достичь 87—88% извлечения урана в продуктивные растворы за 21 день без предварительного предокисления.</p></sec><sec><title>Заключение</title><p>Заключение. Полученные результаты исследований подтверждают перспективность использования шахтного (блочного) и скважинного выщелачивания урана активированными растворами.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Background</title><p>Background. Underground uranium leaching is a promising geotechnological process due to its potential to provide for a radical increase in the technical and economic efficiency, as well as environmental safety, of uranium deposit development. In this article, we discuss the main results in this direction obtained by specialists of the Russian State University for Geological Prospecting.</p></sec><sec><title>Aim</title><p>Aim. To study the processes of uranium leaching by activated solutions, which undergo electrophotochemical treatment prior to contacting with the ore.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Activation preparation of leaching solutions enables the synthesis of active hydrated forms of oxygen and hydrogen with collectivized protons and hydroxyl ions clustered by water molecules. Following the stage of pre-oxidation with an active carbonate solution, a model downhole leaching with chloride-hypochlorite, soda, and sulfuric acid solutions was carried out. Testing percolation leaching of uranium from the ores of the Uchkuduk and Sugraly deposits by activated solutions was conducted at laboratory installations designed by the the Russian State University for Geological Prospecting jointly with the Institute of Mining of Far-East Branch of the Russian Academy of Sciences and Zabaikalsky State University. As a result, the potential of a significant increase in uranium extraction was noted.</p></sec><sec><title>Results</title><p>Results. When leaching with sodium carbonate and ammonium carbonate solutions, the uranium extraction from ore samples from the Sugraly deposit comprised 52% and 59%, respectively. At the same time, the use of an activated solution of sodium percarbonate, which combines the functions of an oxidizing agent and a complexing agent, resulted in an 87–88% uranium extraction into productive solutions during 21 days without preliminary pre-oxidation.</p></sec><sec><title>Conclusion</title><p>Conclusion. The results obtained confirm the prospects of using mine (block) and downhole uranium leaching with activated solutions.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>урановые руды</kwd><kwd>геотехнологии</kwd><kwd>месторождение</kwd><kwd>растворы</kwd><kwd>выщелачивание</kwd></kwd-group><kwd-group xml:lang="en"><kwd>uranium ores</kwd><kwd>geotechnologies</kwd><kwd>deposit</kwd><kwd>solutions</kwd><kwd>leaching</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">Брюховецкий О.С., Секисов А.Г., Лавров А.Ю., Рассказова А.В.
