This paper reviews rare earth minerals (monazite and xenotime) separation by flotation. A wide range of monazite and xenotime flotation test results are summarized including: reasons of variation in the point of zero charges on these minerals, the effects of various flotation conditions on zeta potential of monazite and xenotime, interactions ...

Monazite - an overview | ScienceDirect Topics

Monazite. Monazite is a phosphate mineral [ (Ce,La,Nd,Th)PO4], the major commercial source of Ce. Occurring as small heavy crystals in granitic and gneissic rocks and their detritus (called monazite sands), monazite contains up to 27wt% of U and Th oxides. From: An Introduction to Nuclear Waste Immobilisation (Second Edition), 2014.

[PDF] Separation of cerium (III) from egyptian monazite by ...

The lanthanides hydrous oxides produced from the Egyptian Monazite contain about 45% cerium of the total lanthanides. The high concentration of Ce in this matrix complicates separation of different lanthanides from each other. In this paper a method was developed to separate cerium quantitatively from the lanthanide cake produced from Egyptian Monazite by precipitating tetravalent cerium from ...
