摘要：
The results of extraction separation of the medium group of rare earth elements in the composition of the concentrate of JSC SMF with isomolar mixtures of Aliquat®336–TBP and Cyanex®572–TBP from nitric solutions are discussed. The influence of acidity of an aqueous solution on separation factors of representative pairs of REE and on the value of the capacity of mixtures of extractants is studied. The possibility of extraction separation on the lines of Sm–Gd and Eu–Gd (Aliquat®336–TBP) and on the line of Eu–Sm (Cyanex®572–TBP) is shown.
