In this work, we have investigated a very rich source on valuable elements in mining to valorise and extract the light rare earth elements (REEs) contained in phosphatic mining waste. A detailed characterization was performed for the selected T1 fine dusting (rejection < 0.080 mm) whose mineralo...
More recent data of Greek bauxites from the Parnassos-Ghiona active mines prove that rare earth elements (REEs) occur mainly in the form of authigenic/diagenetic LREE3+ carbonate and phosphate minerals (bastnäsite/parisite group and florencite). Bulk geochemistry of representative samples, from...
Rare earth elements (REEs), a group of 17 elements that comprise 15 lanthanides, scandium, and yttrium in the periodic table with unique properties [1], [2], are useful for the development of green and energy-efficient technologies [3], [4]. Besides their indispensable role in green ...
Rare-earth elements have been used in many examples as the gain medium in WGM microlasers. Stimulated emission has been demonstrated with WGM cavities with samarium28, as well as neodymium, erbium, thulium, and holmium90. Erbium is an interesting gain dopant that can be applied in a sol–gel...
