Эти отходы часто содержат различные вредные примеси тяжелых металлов, представляющие значительный риск для окружающей среды. В данном исследовании на лабораторном уровне была исследована экстракция цинка и меди, а также дополнительно свинца и кадмия из остатков цинковой плавки с использованием гидрометаллургического метода. Был рассмотрен метод выщелачивания для извлечения металлов из остатка. Для оценки эффективности метода выщелачивания были исследованы такие параметры, как концентрация раствора, температура и соотношение твердая/жидкая фаза. В качестве агента выщелачивания использовался водный раствор хлорида аммония (NH4Cl). Оптимальные условия для этого процесса были определены при температуре 80°C, концентрации раствора 5M NH4Cl, времени выщелачивания 2 часа и соотношении жидкое/твердое 1:25. Эти параметры подтвердили высокую селективность агента выщелачивания и продемонстрировали максимальную эффективность. На практике полученный раствор обеспечил максимальное извлечение Zn и Cu в размере 93,2% и 67% соответственно. Кроме того, выходы Pb и Cd составили 80% и 55%. Эти результаты подчеркивают важность оптимизации концентрации хлорида аммония и параметров выщелачивания для повышения эффективности одновременной экстракции различных металлов. Высокая селективность и эффективность хлорида аммония усиливают его потенциал в извлечении металлов и снижают воздействие на окружающую среду, открывая новые возможности для развития методов переработки отходов.</p></abstract><trans-abstract xml:lang="en"><p>The annual increase in waste recycling by non-ferrous metal producers is steadily growing. These waste materials often contain various harmful heavy metal impurities, which pose significant environmental risks. This study examined the laboratory-scale extraction of zinc and copper, along with additional lead and cadmium, from the residue of zinc smelting using a hydrometallurgical method. The leaching technique was considered for extracting metals from the residue. Parameters such as the solution's concentration, temperature, and the solid/liquid ratio were examined to assess the efficiency of the leaching method. An aqueous solution of ammonium chloride (NH4Cl) was used as the leaching agent. Optimal conditions identified for this process were a temperature of 80°C, a 5M NH4Cl solution, a leaching duration of 2 hours, and a liquid/solid ratio of 1:25. These parameters confirmed the high selectivity of the leaching agent and demonstrated maximum efficiency. In practice, the obtained solution yielded maximum Zn and Cu recoveries of 93.2% and 67%, respectively. Additionally, the yields for Pb and Cd were 80% and 55%. These results underline the importance of optimizing the concentration of ammonium chloride and leaching parameters to improve the simultaneous extraction efficiency of different metals. The high selectivity and efficiency of ammonium chloride enhance its potential in metal recovery and reduce the environmental impact, opening new possibilities for developing waste recycling methods.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>медь</kwd><kwd>цинк</kwd><kwd>свинец</kwd><kwd>кадмий</kwd><kwd>металл</kwd><kwd>промышленные отходы</kwd><kwd>гидрометаллургическая переработка</kwd></kwd-group><kwd-group xml:lang="en"><kwd>copper</kwd><kwd>zinc</kwd><kwd>lead</kwd><kwd>cadmium</kwd><kwd>metal</kwd><kwd>industrial waste</kwd><kwd>hydrometallurgical processing</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">Falagan C.
