Изучено влияние соотношения Zn : HСl на химический состав жидкой и твердой фаз, степень извлечения цинка 28%-й соляной кислотой при продолжительности процесса 10 ч. Жидкая фаза содержит в основном хлористый цинк, примеси концентрата, из которых кальций, железо, медь, кадмий, свинец преобладают (кальций – 0,181–0,314 %, железо – 0,011–0,687 %, медь –0,0008–0,326 %, кадмий – 0,0004–0,167, калий – 0,0004–0,389 и свинец – 0,951–1,654 %). Температура процесса выщелачивания при этом – 65–75 °С, давление – 1,72 Мпа. Степень извлечения при этих параметрах составляет 71,22–90,10 % в зависимости от соотношения Zn : HCl. Оптимальное соотношение – 1 : 1,1. Установлено, что взаимодействие цинкового концентрата происходит в кинетической области и продолжается в диффузионной, где значительное влияние оказывает продолжительность процесса. Константа скорости реакции от температуры подчиняется уравнению Аррениуса, а средняя энергия активации составляет 4,05 кДж/моль.</p></abstract><trans-abstract xml:lang="en"><p>The article presents data on the production of zinc chloride by autoclave leaching of zinc from zinc concentrate with hydrochloric acid. The influence of the Zn : HCl ratio on the chemical composition of the liquid and solid phases, and the degree of zinc extraction by 28 % hydrochloric acid at a process duration of 10 hours was studied. The liquid phase contains mainly zinc chloride, concentrate impurities, of which calcium, iron, copper, cadmium, and lead predominate, with the their contents of 0.181–0.314 % for calcium and 0.951–1.654 % for lead. The temperature of the leaching process in this case is 65-75°C, the pressure is 1.72 MPa. The recovery rate at these parameters is 71.22–90.10 % depending on the Zn:HCI ratio. The optimal ratio is 1 : 1.1. It has been established that the interaction of zinc concentrate occurs in the kinetic region and continues in the diffusion region, where the duration of the process has a significant effect. The reaction rate constant versus temperature obeys the Arrhenius equation and the average activation energy is 4.05 kJ/mol.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>цинковый концентрат</kwd><kwd>соляная кислота</kwd><kwd>выщелачивание</kwd><kwd>автоклав</kwd><kwd>хлорид цинка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>zinc concentrate</kwd><kwd>hydrochloric acid</kwd><kwd>leaching</kwd><kwd>autoclave</kwd><kwd>zinc chloride</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">Росилов, М.
