The principle separation processes employed in the beneficiation of rare earth minerals include gravity separation, magnetic separation, electrostatic separation and froth flotation. These processes will be examined as they have been applied to rare earth minerals.density separation listsFL gravity & density separators for minerals. Dense media separation utilises a medium with a density in between the density of the ore and the gangue (commercially worthless) particles. When introduced to this medium, particles either float or sink, depending on their density, as relative to the medium.
