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.

Flame spectra of the rare-earth elements
Spectrochimica Acta, 1962Abstract The rare-earth elements, including scandium and yttrium, emit intense line spectra when absolute ethanol solutions of rare-earth halide or perchlorate salts are aspirated into fuel-rich, oxy-acetylene flames. Recordings of the spectra are given, along with the exact wavelengths of about 1200 of the strongest lines.

They fall into two well-defined groups, the first occurring naturally in reasonably large quantities, the second being radioactive and very largely man-made short life elements. A third group resemble the rare earths to such an extent that they are always classified together.
