Study Of Malaysian Rare Earth Elements: Mineral Characterization Of Monazite And Xenotime Concentrate From Amang [PDF]

, 2022
Amang, widely recognized for mineral tailings in Malaysia, is a cassiterite-tailing or tin oxide (SnO₂) secondary product inevitably formed from mineral separation processes such as gravitational, magnetic, and high-tensional separators.

A Monazite-bearing clast in Apollo 17 melt breccia [PDF]

, 1993
A phosphate-rich clast in a pigeonite-plagioclase mineral assemblage occurs in Apollo 17 impact-melt breccia 76503,7025. The clast, measuring 0.9 x 0.4 mm in thin section, contains 3.3 percent (volume) apatite (Ca5P3O12(F,Cl)), 0.8 percent whitlockite ...

Synthesis and characterization of radiation sensitive TiO2/monazite photocatalyst

, 2008
A TiO2/monazite photocatalyst was prepared by embedding TiO2 nanoparticles into a monazite substrate surface. TiCl4 hydrolysis/citric acid chelating procedure under acidic conditions were used to synthesize the nanophase TiO2 particles.

Phase Decomposition upon Alteration of Radiation-Damaged Monazite-(Ce) from Moss, Ostfold, Norway

, 2010
The internal textures of crystals of moderately radiation-damaged monazite-(Ce) from Moss, Norway, indicate heavy, secondary chemical alteration. In fact, the cm-sized specimens are no longer mono-mineral monazite but rather a composite consisting of ...

Monazite-huttonite solid-solutions from the Vico Volcanic Complex, Latium, Italy

, 1996
The crystal-chemical relationships occurring within a single grain of monazite-(Ce) from Vetralla, Vico Volcanic Complex, north of Rome, are outlined. The sample is from a miarolitic cavity in a holocrystalline ejectum consisting of K-feldspar plus minor

A low-temperature, one-step synthesis for monazite can transform monazite into a readily usable advanced nuclear waste form

: It has been demonstrated that monazite-type materials are excellent candidates for nuclear waste forms, and hence, their facile synthesis is of great importance for the needed sequestration of existing nuclear waste.

Interpretation of U-Th-Pb in-situ ages of hydrothermal monazite-(Ce) and xenotime-(Y): evidence from a large-scale regional study in clefts from the western alps

, 2016
International audienceIn eleven Alpine clefts of the western Alps, in-situ dating of monazite-(Ce) and xenotime-(Y) has been attempted to gain insights on possible disturbances of the geochronological U-Th-Pb systems and age interpretations in ...
