View Rare Earth Elements Research Papers on Academia.edu for free.The research team explored using mineral and organic acids, including a bio-acid mixture, to extract six rare earth elements (yttrium, cerium, neodymium, samarium, europium and ytterbium) from.Rare earth elements (REE) include the lanthanide series elements (La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, and Lu) plus Sc and Y. Currently these metals have become very critical to several modern technologies ranging from cell phones and televisions to LED light bulbs and wind turbines.


The first Rare Earth Research Conference (RERC) was organized by Eugene V. Kleber at Lake Arrowhead, California in 1960. Ames hosted the 5th RERC in 1965. After 52 years, another conference was overdue, so now alternates on a three-year cycle with the International Conference on f-Elements (Europe) and the International Conference on Rare Earths.Mining rare earths is tricky, both environmentally and economically. The prospectivity of a resource is determined by several factors, including grade, cost of processing, impurities and the relative concentration of the rare earth elements in greatest demand.

Rare earth elements (REEs) including fifteen lanthanides, yttrium and scandium are found in more than 250 minerals, worldwide. REEs are used in various high-tech applications across various.

Rare earth elements play a vital and increasing role in a wide range of consumer electronics, in environmental technologies and in military applications. Although rare earth deposits are known in several countries, production in recent years has been strongly concentrated in a very few locations.

Rare earth minerals are among the commodities most threatened by these increasingly hostile foreign policies. According to 2018 data from the US Geological Survey, the US is entirely reliant on imports for its supply of rare earth minerals, with 78% of all such imports coming from China, orders of magnitude ahead of the second-largest importer to the US, Estonia, which is responsible for 6% of.

Rare Earth Hypothesis In planetary astronomy and astrobiology, the Rare Earth hypothesis argues that the emergence of complex multicellular life on Earth (and, subsequently, intelligence) required an improbable combination of astrophysical and geological events and circumstances.

Hydrogen release behavior from rare earth oxides (REOs) (Y 2 O 3, Sm 2 O 3, Eu 2 O 3, Gd 2 O 3, Dy 2 O 3, Er 2 O 3, and Yb 2 O 3) exposed to 133 Pa of deuterium (D 2) gas or 2 kPa of heavy water (D 2 O) vapor at 873 K for 5 h was examined using thermal desorption spectroscopy. Hydrogen solubility and diffusivity in Y 2 O 3, Gd 2 O 3, Dy 2 O 3, Er 2 O 3, and Yb 2 O 3 exposed to a deuterium.

A process is demonstrated for the efficient separation of rare earth elements, using a combination of selective reduction and vacuum distillation of halides. The large differences in the redox chemistry of the rare earth elements and in the vapor pressures of rare earth di- and trihalides are exploited for separation. Experimental proof of concept is provided for the binary systems.
