A review of rare earth minerals flotation: Monazite and

1/11/2015· Rare earth mineral separation by flotation isplex procedure. The objective of this review was to present and identify the effects of different flotation conditions on monazite and xenotime flotation. From the available literature, it can be concluded that the main reason for PZC differences in monazite and xenotime is attributed to the different anion properties. It has been found that

A new collector for rare earth mineral flotation

1/12/1997· A new collector for bastnaesite flotation modified hydroxamic acid MOHA has been developed through several years laboratory research. The experimental results of flotation of pure bastnaesite mineral and rare earth ores, and the application experience in flotation plants showed that MOHA is an efficient collector for bastnaesite flotation.
