Separation of Light and Middle-Heavy Rare Earths from rare earths la ce pr nd sm eu gd

Rare earth elements (REEs) are the group of 15 metallic, chemical elements with atomic numbers from 57 to 71 and also scandium and yttrium (Hussein, 1996; Jorjani and Shahbazi, 2012). They are divided into three groups: the light (La, Ce, Pr, Nd), middle (Sm, Eu, Gd, Tb) and heavy (Y and Dy to Lu) rare earths Sample Preparation Guides - Inorganic VenturesThe Rare Earth (RE) elements include Y, La, and the Lanthanides (Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu). The chemistry of these elements is sufficiently similar that they can be treated as a group rather than individually. RE elements are technically the elements grouped as the 'Lanthanides', which are Ce thru Lu.Review on hydrometallurgical recovery of rare earth metals rare earths la ce pr nd sm eu gdOct 01, 2016 · In this process, mixed rare earths chloride is fractionated into 3 streams LaCePrNd fraction, SmGdEu rich fraction and Y-heavy rich fraction using 30% saponified PC 88A via large number of stages in mixer settlers due to low separation factors of rare earth metals (Maharana and Nair, 2005).
