Актуальность темы обусловлена высоким спросом на редкие металлы, ограниченностью их минеральных источников и необходимостью вовлечения техногенных образований в переработку. Объектами исследования выступали отвальный шлам титанового хлоратора, возгоны пылевой камеры и расплав пылеосадительной камеры с солевой ванной.Методами рентгенофлуоресцентного анализа, рентгенофазового анализа и сканирующей электронной микроскопии установлено, что ниобий в указанных продуктах содержится в форме устойчивых оксидов и смешанных фаз с участием титана, алюминия, железа и кальция. Проведены эксперименты по водному и кислотному выщелачиванию с использованием соляной, серной и плавиковой кислот. Установлено, что наибольшее извлечение ниобия (до 53%) достигается при обработке фторсодержащими растворами при температуре 85-95 °C и соотношении твёрдой и жидкой фаз 1:10-1:15.Термодинамический анализ хлорирования ниобийсодержащих соединений и построение диаграмм Пурбе подтвердили высокую устойчивость оксидов ниобия и эффективность их перевода в раствор в форме фторниобатов. Предложенный подход объединяет физико-химические методы анализа с расчётным моделированием и может быть использован при проектировании технологии селективного извлечения ниобия. Полученные результаты способствуют расширению минерально-сырьевой базы редких металлов и снижению экологической нагрузки на предприятия титановой промышленности.</p></abstract><trans-abstract xml:lang="en"><p>This article presents the results of a study on the processing of industrial by-products from titanium tetrachloride production for the purpose of niobium extraction. Three types of niobium-containing materials were studied: titanium chlorinator sludge, dust chamber sublimate, and molten slag from the dust-settling chamber with a salt bath. The chemical and phase compositions were investigated using SEM-EDS, XRF, and XRD methods. Niobium was found predominantly in the form of refractory oxides and complex phases. Thermodynamic modeling using HSC Chemistry confirmed the stability of niobium oxides and the possibility of chlorination to volatile chlorides in a reducing environment. Leaching experiments showed that traditional water and acid treatments (HCl, H₂SO₄) result in low niobium extraction rates (up to 26%), whereas HFcontaining solutions allow for recovery of up to 53%. Based on experimental and modeling data, optimal parameters for selective niobium extraction were established. The proposed approach enables efficient recovery of valuable rare elements and contributes to the reduction of environmental impact from titanium production residues.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>ниобий</kwd><kwd>тетрахлорид титана</kwd><kwd>промышленные побочные продукты</kwd><kwd>хлорирование</kwd><kwd>выщелачивание</kwd><kwd>экстракция</kwd><kwd>термодинамический анализ</kwd><kwd>фазовый состав</kwd><kwd>фторниобаты</kwd><kwd>переработка титансодержащего сырья</kwd></kwd-group><kwd-group xml:lang="en"><kwd>niobium</kwd><kwd>titanium tetrachloride</kwd><kwd>industrial by-products</kwd><kwd>chlorination</kwd><kwd>leaching</kwd><kwd>extraction</kwd><kwd>thermodynamic analysis</kwd><kwd>phase composition</kwd><kwd>fluoroniobates</kwd><kwd>titanium feedstock processing</kwd></kwd-group><funding-group xml:lang="ru"><funding-statement>Данное исследование профинансировано Комитетом науки Министерства образования и науки Республики Казахстан (грант № AP22686490).</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">Agulyansky A.
