Monazite - CONCENTRATION OF MINERALS

Other major monazite sources are heavy mineral sands from so-called placerdeposits which are usually mined by dredging or scraping, followed by screening and concentration in spiral concentrators. Mineral concentrates are then washed, dried and fed into magnetic separators to remove e.g. ilmenite and other magnetic minerals.

Gravity separation - Wikipedia

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force.
