The Couche 3 (C3) of Sidi Daoui has long been considered an unexploitable low-grade phosphate stratum and was left behind. Nowadays, with the exhaustion of high-grade phosphate resources, the l'Office Chérifien des Phosphates (OCP) Group plans to launch the exploitation of C3 by private mining companies. This study was undertaken under the authority …

The annual consumption of phosphate rock approached 150 million tons. The marketable phosphate is usually 30% P 2 O 5 or higher. 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.
