Chehreh Chelgani, S.; Rudolph, M.; Leistner, T.; Gutzmer, J.; Peuker, U. A.

This paper reviews rare earth minerals (monazite and xenotime) separation by flotation. A wide range of monazite and xenotime flotation test results are reviewed including: reasons of variation in the point of zero charges on these minerals, the effects of various flotation conditions on zeta potential and the point of zero charges on the surface of monazite and xenotime, interactions of collectors and depressants on the surface of these mineral phases during flotation separation, relationship between surface chemistry of the minerals and different types of collector adsorptions, effects of the conditioning temperature on flotation of rare earth minerals. This review summarizes various approaches for selective separation of monazite and xenotime by flotation for further research in future.
