The use of pracaxi oil collector in the selective flotation of xenotime from silicates [PDF]
Heliyon, 2023 Rare earth elements have played a key role in technological advancement, attracting great visibility in the global commodity market. Xenotime, a heavy rare earth resource (YPO4), can be found associated with granitic rocks, as in the Pitinga deposit ...

Xenotime from Morrua, Mozambique [PDF]
Bulletin of the Geological Society of Finland, 1973 Xenotime, found as well formed crystals in a heavy mineral concentrate from the Morrua pegmatite mine in Mozambique, was studied. The mineral occurs in the sample in two generations, clearly distinguishable from each other.

An X-ray diffraction method for determining the amount of xenotime in a zircon sample [PDF]
Bulletin of the Geological Society of Finland, 1984 An X-ray method was developed for determining the amount of xenotime or zircon in a zircon ‒ xenotime sample. Such analyses are useful in establishing whether a solid solution exists between xenotime and zircon or whether there is a separate xenotime ...

Source-Independent Enrichment of Light Lanthanides: Microbial Mobilization, Selective Uptake, and Intracellular Storage. [PDF]
Environ MicrobiolOnly light lanthanides facilitate lanthanide‐dependent methylotrophy. In Beijerinckiaceae bacterium RH AL1, light lanthanides are enriched from diverse sources, including poorly soluble minerals, through a multilayered process involving mobilisation, selective uptake, and intracellular periplasmic storage.
