Physical and Chemical Beneficiation of the Egyptian Beach Monazite
Most of the monazite grains are reversible negative and are attracted towards the positively charged static electrode. Using wet gravity concentration, both low and high intensity magnetic separation, and electrostatic separation techniques, a high grade concentrate assaying 97 wt. % monazite with a recovery of 76.8% can be obtained.

Mineral Sands: NORM Appendix
Monazite is thus normally returned to the mine and dispersed with the tailings. Western Australian mineral sands deposits contain up to 10% heavy minerals, of which 1-3% is monazite. This in turn typically contains 5-7% of radioactive thorium and 0.1-0.3% of uranium, which is barely radioactive.

Process development to recover rare earth metals from monazite …
If monazite is chemically processed, the purity of monazite concentrate is upgraded to ∼98% using magnetic separation, otherwise the purity stream may be as low as 30%. Thus, monazite or other minerals are separated and concentrated after coarse grinding via gravity separation, flotation, electrostatic separation or magnetic processes ...

Monazite
Monazite is a resinous to vitreous mineral with a yellowish-brown to reddish-brown or greenish-brown lustre. It's transparent, and big grains or well-formed crystals are uncommon. Where monazite is abundant locally, granular masses can be seen. It has a cleavage that is pleasant and distinct. It has a hardness of 5 to 5.5.
