      <abstract xml:lang="ru">
        <p>Присутствие в рудах цветных металлов, а следовательно, и в растворах, получающихся при их переработке, больших количеств железа осложняет технологический процесс экст­ракции этих металлов нафтеновыми кислотами. Так, наличие в составе экстракта нафтената двухвалентного железа затруд­няет реэкстракцию никеля и кобальта из органической фазы. В связи с этим представляет интерес изучение состава и свойств этой соли.</p>

      <abstract xml:lang="en">
        <p>The presence of large amounts of iron in the ores of non-ferrous metals, and consequently in the solutions obtained during their processing, complicates the technological process of extraction of these metals with naphthenic acids. Thus, the presence of divalent iron naphthenate in the extract makes it difficult to re-extract nickel and cobalt from the organic phase. In this regard, it is of interest to study the composition and properties of this salt.</p>
