摘要

对俄罗斯和国外在过去十年间发表的关于使用不同种类萃取剂的二元混合物萃取稀土元素（REEs）的文献数据进行了回顾。结果表明，在大多数情况下，由于有机相中混合成分络合物的形成，通过提高所用萃取剂混合物的选择性，可以获得较高的稀土元素分离系数。此外，在某些使用萃取剂混合物的系统中，从有机相中剥离金属的过程也变得更加容易。

The Use of Mixtures of Extractants for the Recovery and Separation of Rare Earth Elements

A review was made of the literature data published in Russia and abroad over the past ten years on the extraction of rare earth elements (REEs) with binary mixtures of extractants of various classes. It was noted that high values of REE separation coefficients are in the most cases achieved by increasing the selectivity of the extractant mixtures used due to the formation of complexes of mixed composition in the organic phase. In addition, in some systems with mixtures of extractants, the processes of stripping metals from the organic phase are facilitated.
