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.

Unsupervised machine learning (ML) techniques are applied to the characterization of the adsorption of rare earth elements (REEs) by zeolites in continuous flow. The successful application of principal component analysis (PCA) and K-Means algorithms from ML allowed for a wide range assessment of the adsorption results. This …

Abstract. Constituting the bulk of rare-earth elements, lanthanides need to be separated to fully realize their potential as critical materials in many important technologies. The discovery of new ligands for improving rare-earth separations by solvent extraction, the most practical rare-earth separation process, is still largely based on trial ...

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.

The 17 rare earth elements, or lanthanides, consist of elements 21 (scandium), 39 (yttrium), and 57 (lanthanum) to 71 (lutetium). The rare earths were so named because of their low concentration in minerals which were scarce. However, some of the elements are not as rare as once thought. Today, the rare earths are important for …

1. Radiation Beneficiation Method. It mainly uses the difference in thorium content between rare earth minerals and gangue minerals in the ore, and uses a γ-ray radiation concentrator to separate rare earth minerals from gangue minerals. The radiation beneficiation method is mostly used for the pre-selection of rare earth ore.
