        <p>Для разработки новых способов извлечения и разделения редкоземельных металлов, эффективных при гидрометаллургических переделах бедного сырья, например эвдиалитовых концентратов, были экспериментально определены коэффициенты распределения и разделения редкоземельных металлов из водных растворов органическими экстрагентами. на основе опытных данных выявлен механизм экстракции, проведен расчет термодинамических констант.</p>

        <p>The purpose of this research is to develop a new method of extraction and separation of rare earth metals, which will be effective in hydrometallurgical processes, i.e. in the processing of eudialyte concentrate. The task of the research is the experimental determination of distribution and separation coefficients in solvent extraction of rare earth metals from aqueous solutions with organic extractants, as well as the calculation of the extraction mechanism and thermodynamic constants on the basis of experimental data.</p>
