Rare earth elements are a group of seventeen chemical elements that occur together in the periodic table (see image). The group consists of yttrium and the 15 lanthanide elements (lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium, and lutetium).

Humphries (2010) mendefinisikan Rare Earth Element and Yttrium (REY) sebagai kelompok unsur logam yang termasuk ke dalam golongan transisi atau kelompok kimia lantanida pada tabel periodik. Unsur Skandium (Sc) dan Yttrium (Y) juga termasuk kedalam kelompok REY karena kesamaan sifat fisika dan kimiawi golongan lantanida.

Rare earth elements (REE) concentrations and pattern remains largely unchanged during the process of milling and can thus provide strong evidence of the origin of the material. The aim of this study was to determine the rare earth elements in uranium ore deposits as a nuclear forensics tool. Uranium ore from three mines were collected …

There are 17 rare earth elements (REEs), 15 within the chemical group called lanthanides, plus yttrium and scandium. The lanthanides consist of the following: lanthanum, cerium, praseodymium, neodymium, promethium, samarium, europium, gadolinium, terbium, …

Abstract. Rare earth elements (REEs) are important for green and a large variety of high-tech technologies and are, therefore, in high demand. As a result, supply with REEs is likely to be disrupted (the degree of depends on the REE) in the near future. The 17 REEs are divided into heavy and light REEs.

President Trump and various U.S. lawmakers have expressed concerns about U.S. reliance on critical mineral imports and potential disruption of supply chains that use critical minerals for various end uses, including defense and electronics applications. Chinese export quotas on a subset of critical minerals referred to as rare earth elements REEs and Chinas …

The rare-earth elements (REEs) are fundamental to many aspects of present-day society and have a variety of non-substitutable uses in modern technology (Table I). 1 REEs consist of the 15 lanthanide elements (often with scandium (Sc) and yttrium (Y) included) as outlined in Table I, 2 each of which has distinctive characteristics …
