Phosphate recovery: The phosphate waste rock piles contain around 45–50% of the coarse material (>30 mm) that can be separated by screening for ore sorting. The recovered indured phosphate constituting around 25% of the PMWR can be valorized by joining the conventional mineral processing with the fine fraction (<30 mm).
