Centrifugal Concentration of Rare Earth Minerals from

Flotation separation of bastnaesite from carbonate gangue has proved to be an exceedingly difficult task, yet it remains the dominant unit operation for beneficiation of rare earth element bearing minerals. The high specific gravity of these minerals (bastnaesite and monazite) in relation to the gangue (calcite) suggests the opportunity for beneficiation through gravity separation.

As the dominant potassium bearing mineral in the Mboukoumassi deposit, it is important that carnallite is distinguished from gangue minerals, such as anhydrite, glauberite, halite, and tachydrite. Since carnallite and halite have the same origin and are typically associated, it is difficult to distinguish between them and also to distinguish them from other gangue minerals.
