      <abstract xml:lang="ru">
        <p>Возможность успешного применения нафтеновых кислот для экстракционного извлечения цветных и редких металлов установлена многочисленными исследованиями. Широкому промышленному применению этого экстрагента из цветной металлургии препятствует неизбежное наличие ионов трехвалентного железа в исходных растворах. Для удаления этих ионов предлагается использование других экстрагентов (например, жирных кислот) или гидролитическое осаждение, что несомненно осложняет технологический процесс ...</p>

      <abstract xml:lang="en">
        <p>The possibility of successfully using naphthenic acids for extractive extraction of non-ferrous and rare metals has been established by numerous studies. The widespread industrial use of this extractant from non-ferrous metallurgy is hindered by the unavoidable presence of ferric ions in the initial solutions. To remove these ions, it is proposed to use other extractants (for example, fatty acids) or hydrolytic precipitation, which undoubtedly complicates the technological process...</p>
