The important mineral apatite, ideally Ca 5 (PO 4) ... Processing of this ore type largely depends upon the type of gangue present in the ore. Complex—iron titanium phosphate ores. These are of granite gneiss origin and may also contain pyroxenite. Some of the ore types may contain pyrochlore minerals.

Apatite (Ca 5 (PO4) 3 (F–Cl–OH)) is a calcium phosphate that is ubiquitous in mafic–ultramafic intrusions. It can preserve the trace element characteristics of its parent magma and the evolutionary record of various volatiles (F, Cl, S, H 2 O) in the magma (Sha and Chappell, 1999; McCubbin et al., 2015; Li and Hermann, 2017; O'Sullivan et al., 2020; Li et al., 2020).
