The Surface Chemistry and Microflotation of Xenotime and Depression of Gangue Minerals [PDF]
, 2018 A pre-concentrated xenotime sample and four selected gangue minerals, ilmenite, zircon, schorl and staurolite were used in this project. Using Octano-hydroxamic acid as a collector, the surface chemistry was investigated through surface area measurements,

Rare Earth Separation Using Monazite and Xenotime [PDF]
, 2016 A collection of methods to separate rare earth elements are presented here. The first is a two-step separation method using low temperature direct synthesis of monazite followed by a low temperature precipitation of xenotime. Another method presented is

Recovery of Xenotime and Florencite from Silicate Minerals Using a Combined Technique of Magnetic Separation and Flotation [PDF]
Xenotime (YPO4), a significant phosphatic minerl rich in heavy rare earth elements (HREEs), typically associates with granitic rocks, exemplified in the Wolverine rare earth deposit in Australia.
