Для описания кинетики процесса использовалась модель сжимающегося ядра. В качестве основного сырья для проведения исследований были использованы минералы халькопирит Воронцовского и борнит Карабашского месторождений. Растворы анализировали оптико-эмиссионным спектральным методом, кеки – волновым рентгенофлуоресцентным. Обработка результатов исследований осуществлялась с помощью пакета прикладных программ MS Excel. Проведены исследования по изучению влияния различных факторов (температуры, концентрации растворителя, крупности частиц и продолжительности процесса) на степень растворения минералов. Температурный диапазон варьировался от 35 до 95°C, концентрация HNO₃ изменялась от 1 до 9 моль/дм³, размер частиц – от +0,1 до 0,056 мм, продолжительность – от 0 до 60 мин. Установлено, что увеличение температуры и концентрации кислоты значительно повышает степень растворения как халькопирита, так и борнита. Показано, что уменьшение размера частиц также способствует более эффективному растворению обоих минералов в азотной кислоте. Рассчитанные значения энергии активации составили 55 кДж/моль для халькопирита и 43 кДж/моль для борнита, соответственно, что характерно для кинетической области протекания процесса. Были определены порядки реакции по реагенту: 1,62 для халькопирита и 1,57 для борнита, а также по размеру частиц: -1,16 для халькопирита и -2,53 для борнита. Эти данные позволили вывести обобщенные уравнения кинетики растворения обоих минералов. Таким образом, на основании проведенных расчетов и анализа результатов было сделано предположение, что процесс растворения халькопирита и борнита в изучаемых условиях протекает в кинетическом режиме</p></abstract><trans-abstract xml:lang="en"><p>The kinetic characteristics of dissolution of copper-bearing sulfides – chalcopyrite (CuFeS₂) and bornite (Cu₅FeS₄) – in nitric acid were studied. The kinetics of the dissolution process was described using a compressible nucleus model. Chalcopyrite of the Vorontsovskoye deposit and bornite of the Karabash deposit were used as research objects. Solution and cake samples were analyzed by optical emission spectrometry and X-ray fluorescence analysis, respectively. The results obtained were processed in the MS Excel software package. The influence of various factors, including temperature, solvent concentration, particle size, and process duration on the dissolution degree of minerals was studied. The process parameters were varied as follows: temperature – from 35 to 95°C; HNO₃ concentration – from 1 to 9 mol/dm³; particle size – from +0.1 to 0.056 mm; duration – from 0 to 60 min. It was established that an increase in temperature and acid concentration leads to a significant increase in the degree of dissolution of both chalcopyrite and bornite. A decrease in particle size also contributes to a more efficient dissolution of both minerals in nitric acid. The calculated activation energy values were 55 kJ/mol for chalcopyrite and 43 kJ/mol for bornite, which is characteristic of the kinetic region of the process. The reaction orders in terms of reactant were determined: 1.62 for chalcopyrite and 1.57 for bornite. In terms of particle size, these were -1.16 for chalcopyrite and -2.53 for bornite. On this basis, generalized equations of dissolution kinetics for both minerals were derived. The results obtained allow an assumption about the kinetic nature of dissolution of chalcopyrite and bornite under the studied conditions.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>медь</kwd><kwd>железо</kwd><kwd>халькопирит</kwd><kwd>борнит</kwd><kwd>растворение</kwd><kwd>азотная кислота</kwd><kwd>кинетические характеристики</kwd><kwd>энергия активации</kwd><kwd>кинетическое уравнение</kwd></kwd-group><kwd-group xml:lang="en"><kwd>copper</kwd><kwd>iron</kwd><kwd>chalcopyrite</kwd><kwd>bornite</kwd><kwd>dissolution</kwd><kwd>nitric acid</kwd><kwd>kinetic characteristics</kwd><kwd>activation energy</kwd><kwd>kinetic equation</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Госзадания Российской Федерации по Гранту № 075-03-2024-009/1 (FEUZ-2024-0010)</funding-statement><funding-statement xml:lang="en">The study was carried out with the financial support of the State Assignment of the Russian Federation under the Grant no. 075-03-2024-009/1 (FEUZ-2024-0010)</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">Japel S., Schwager B., Ross M., Boehler R.
