Hydrothermal monazite : the unavoidable accessory

, 2016
La monazite est présente comme minéral accessoire dans la plupart des environnements géologiques. Elle est souvent riche en U et Th, n’incorpore pas (ou peu) de Pb initial et son système isotopique (U-Th-Pb) est résistant à la diffusion dans la majorité ...

Characteristics of Treated Monazite in Different Particle Sizes to Upgrade the Rare Earth Elements Content by Using Mechanochemical and Roasting Processes

International Journal of Technology
Rare earth metals (REE) constitute one of the most crucial groups of elements globally. In Indonesia, deposits of REE have been recognized within monazite minerals extracted from tin mining operations in Bangka.

Thorium substitution in monazite: case studies and forward modelling [PDF]

, 2019
The accessory mineral monazite [(REE, Th, U, Y, Ca)(P, Si)O] is the major host of the heat producing element Th in the high temperature (>500 C) continental crust, hosted predominantly in peraluminous rock types.

Electron backscatter diffraction analysis and orientation mapping of monazite

, 2010
Electron backscatter diffraction (EBSD) analysis of monazite requires a comparison of empirically collected electron backscatter patterns (EBSPs) with theoretical diffraction data, or 'match units', derived from known crystallographic parameters ...

Study on Extraction of Lanthanum Oxide from Monazite Concentrate

, 2008
Lanthanum oxide is to be recovered from monazite, which contains about 13.44% lanthanum oxide. The principal objective of this study is to be able to extract lanthanum oxide from monazite of Moemeik Myitsone Area.
