Rare earth element geochemistry of kimberlite
Physics and Chemistry of the Earth, 1975Abstract Abundances of rare earth elements (REE), Sc, Co, Hf, Ta and Th have been determined by neutron activation analysis in kimberlites from the Wesselton pipe, in micaceous kimberlites from the Swartruggens fissure and kimberlite from the Monastery Mine, Ison Creek and Somerset Island pipes. Kimberlites are characterized by a high REE content and

Removal and potential recovery of rare earth elements from mine water
, 2020Recovery of rare earth elements (REE) from acid mine drainage (AMD) could be an alternative to their conventional mining, given that REE are relatively highly concentrated in AMD.

Mossbauer spectroscopy of the rare-earth elements as a group has gained considerable attention from physicists. Successive addition of 4f-electrons along the series has little influence on many of the chemical properties, which are mainly those of a tripositive cation.

Molecular Polyarsenides of the Rare‐Earth Elements
Angewandte Chemie International Edition, 2015AbstractReduction of [Cp*Fe(η5‐As5)] with [Cp′′2Sm(thf)] (Cp′′=η5‐1,3‐(tBu)2C5H3) under various conditions led to [(Cp′′2Sm)(μ,η4:η4‐As4)(Cp*Fe)] and [(Cp′′2Sm)2As7(Cp*Fe)]. Both compounds are the first polyarsenides of the rare‐earth metals. [(Cp′′2Sm)(μ,η4:η4‐As4)(Cp*Fe)] is also the first d/f‐triple decker sandwich complex with a purely inorganic ...

Biological leaching of rare earth elements
World Journal of Microbiology and Biotechnology, 2020The distinctive physico-chemical features of rare earth elements (REEs) have led to an increase in demand by the global market due to their multiple uses in industrial, medical and agricultural implementations. However, the scarcity of REEs and the harsh eco-unfriendly leaching processes from primary sources beside obliviousness to their recycling from

Intermetallic phases between tungsten and rare earth elements have only been found for the W-Ce system. Two phases exist in this system, which are formed by peritectic reactions; one of them is believed to be W2Ce, “Elliott” (1965), p. 314.
