Xenotime, a phosphate ore, is one of the valuable mineral deposits of rare earths similar to monazite.The main characteristics of xenotime are listed below: (1) The content of yttrium is high while that of the light rare earths is low (Table 12). (2) The content of thorium is lower than that in monazite (Table 13). (3) The composition of tungsten-containing xenotime …

Xenotime grows in sediments during diagenesis, in low- to granulite-grade metamorphic rocks, in migmatites, and is common in peraluminous igneous rocks. …
Xenotime (YPO 4) is iso-structural with zircon-group minerals and lies at one end of a compositional solid-solution with monazite.As with monazite and zircon, naturally occurring xenotime may accommodate significant concentrations of rare earth elements, as well as Th and U, making it an important repository for these valuable …
The first time I heard the term "rock crusher" was in reference to the transmission in the 1967 L88 Corvette. Due to the low gear angle there is a fair amount of gear noise, really like a medium / heavy duty truck transmission.
Hydrothermal xenotime was found and concluded to be younger than the surrounding host rock within a 200-kilometer radius of the initial source [45] . Upon further investigation, it was
The Maw zone rare earth element (xenotime) deposit is hosted in brecciated sandstones in the Athabasca Basin and is associated with silicification, hematitization, …
Xenotime is a widespread accessory mineral in lower greenschist to upper amphibolite facies metasedimentary rocks from the Palaeoproterozoic Mount Barren Group, southwestern Australia. Xenotime is closely associated with detrital zircon, commonly forming syntaxial outgrowths, in samples of sandstone, micaceous quartzite, slate, …
Monazite and xenotime are the two most useful and commonly used geochronometers for deciphering ages from metamorphic rocks. The low analytical cost involved in electron probe micro-analyser chemical dating, ease of sample preparation and abundance in metamorphic rocks of wide P–T conditions make monazite and xenotime …
The type of rock crusher required depends on moisture content, the hardness of the material, and your desired product size. Crushing may take place in one process with a single crusher. However, secondary and tertiary crushing can be used to further break your material down to the desired size. Many processing plants or rock crushing plants ...

Xenotime describes a group of several closely related phosphates, arsenates, and vanadates composed of rare earth elements.The term is generally used to describe the most common member of the group, Xenotime-(Y), which is the yttrium phosphate end member of this series.. Other, rarer members of the Xenotime series include Xenotime …
were as presented in Table 1. It was shown that xenotime contained less than 1% of thorium and uranium, while monazite had a slighter higher percentage of thorium as compared to uranium. Table 1. Percentage of thorium and uranium analysed from xenotime and monazite Mineral Thorium (%) Uranium (%) Raw xenotime 0.62 0.57 …
