A critical review on solvent extraction of rare earths from …
D2EHPA has also been used to separate Sm, Eu, and Gd from the other rare earths in a mixed nitrate-chloride leachate from monazite ( Rabie, 2007 ). D2EHPA can extract rare earth at low pH values, but because the equilibrium of Eqs. (1), (2) lies strongly to the right it is difficult to strip the loaded metals.

A clean way to extract rare earth metals
Rare earth metals — those 17 chemically similar elements at the bottom of the periodic table — are in almost every piece of technology we use from cell phones to wind turbines to electric cars. Because these elements are so similar to each other, the process of separating them is time consuming, expensive, and dangerous.

After first extraction step, the rare earth metals were extracted from the raffinate using solvating extractant Cyanex 923 and Aliquat 336 nitrate. The advantage of selecting Aliquat 336 nitrate over Cyphos 101 was the selectivity of the former towards rare earth metals and also less number of Cyanex 923 can accommodate around it.
