The process transforms phosphate mineral to the defluorinated phosphate with a P/F ratio of more than 100. Calcined product is cooled and screened to defluorinated phosphate rock (DFP) or tri-calcium phosphate (TCP) (Bandyopadhyay, 1999). Because it has a low enough fluoride to phosphorus ratio, and the phosphorus is bio-available, it is ...
Physical and thermal treatment of phosphate ores — An …
The run-of-mine material is mostly of lower grade which needs processing or upgrading. The processing techniques of phosphate ores depend mostly on the type of associated gangue minerals present in the mined rock. In some cases, simple, inexpensive techniques are enough to produce the required grade.
