Separation of Monazite from Placer Deposit by Magnetic Separation …
On the other hand, quartz with a relatively low density (2.65 g/cm 3) can be easily separated from ilmenite (4.8 g/cm 3) and monazite (4.8–5.5 g/cm 3), which have a high density, by gravity separation. However, it is difficult to separate ilmenite and monazite from each other owing to a similar specific gravity.
