Apatite is the most common phosphate mineral [Ca 5 (Cl, F, OH)(PO 4) 3] and the main raw material to produce fertilizers based on phosphorus. The achievement of P 2 O 5 grade required to the next steps of purification processes (wet chemical methods) is performed through direct anionic flotation process in Brazil's ore beneficiation plants.

Basics of mineral processing - SlideShare

Basics of mineral processing. Treatments of ores to concentrate their valuable constituents (minerals) into products (concentrate) of smaller bulk, and simultaneously to collect the worthless material (gangue) into discardable waste (tailing), are called as ore dressing/ mineral processing methods. This module explains the methods adopted in ...

12%The apatite concentrate contains ≈40% P 2 O 5 (Notholt 1979 ). The potential use of ores and minerals depends mainly on the performance of the extraction techniques used to separate and/or preconcentrate the REEs. Trace concentrations of REEs are present as impurities in certain ores and minerals, e.g., apatite, columbite, tantalite, and others.
