Lanthanide Sulfate Recovery by Synergistic Dimethyl Ether and Na₂SO₄ Fractional Crystallization. [PDF]

ChemSusChem
This work demonstrates synergistic lanthanide salt recovery from an aqueous magnet leachate to single ppm concentrations using Na2SO4 combined with dimethyl ether crystallization. This waste valorization process minimizes chemicals consumed and waste generated while maximizing the recovery of a critical material product. Lanthanides (Lns) are important

Comparative Binding Studies of the Chelators Methylolanthanin and Rhodopetrobactin B to Lanthanides and Ferric Iron. [PDF]

Chembiochem
The synthesis and the investigation of the lanthanide (Ln) and Fe‐binding properties of the putative lanthanophore methylolanthanin (MLL) and the siderophore rhodopetrobactin B (RPB B) are reported. While both chelators bind Lns, they unexpectedly precipitate with Lns under biologically relevant conditions and thereby challenge the proposed classic ...

Palaeoproterozoic prograde metasomatic-metamorphic overprint zones in Archean tonalitic gneisses, eastern Finland [PDF]

Bulletin of the Geological Society of Finland, 1999
Several occurrences of coarse-grained kyanite rocks are exposed in the Archaean area of eastern Finland in zones trending predominantly northwest-southeast that crosscut all the Archaean structures and, locally, the Palaeoproterozoic metadiabase dykes ...

Helium Diffusion in Natural Xenotime [PDF]

Geochemistry, Geophysics, Geosystems, 2019
AbstractThe typically high U and Th contents of xenotime ([Y,HREE]PO4) make this accessory mineral a promising candidate for (U‐Th)/He thermochronometry if the 4He diffusivity can be constrained well enough to estimate its closure temperature. We report new results for two 4He step‐heating experiments on different‐sized fragments of a natural xenotime ...

Investigation of the Microstructure of Fine-Grained YPO₄:Gd Ceramics with Xenotime Structure after Xe Irradiation

Ceramics, 2022
This paper reports on the preparation of xenotime-structured ceramics using the Spark Plasma Sintering (SPS) method. Y0.95Gd0.05PO4 (YPO4:Gd) phosphates were obtained using the sol-gel method.

Corona formation around monazite and xenotime during greenschist-facies metamorphism and deformation [PDF]

European Journal of Mineralogy, 2020
Epidote/allanite–fluorapatite coronae around monazite and xenotime are investigated in Permian pegmatites deformed under greenschist-facies conditions during Alpine tectonometamorphism in the Austroalpine basement, Eastern Alps.

Hydrothermal formation of heavy rare earth element (HREE)– xenotime deposits at 100 °C in a sedimentary basin [PDF]

, 2018
Most rare earth element deposits form from magmatic fluids, but there have also been discoveries of heavy rare earth element (HREE)– enriched hydrothermal xenotime deposits within sedimentary basins.

A Spectroscopic Investigation of Eu3+ Incorporation in LnPO4 (Ln = Tb, Gd1-xLux, X = 0.3, 0.5, 0.7, 1) Ceramics

Frontiers in Chemistry, 2019
We have investigated the incorporation of the luminescent Eu3+ cation in different LnPO4 (Ln = Tb, Gd1−xLux, x = 0.3, 0.5, 0.7, 1) host phases. All samples were analyzed with powder X-ray diffraction (PXRD), Raman spectroscopy, and site-selective time ...
