Moroccan phosphate ores have important phosphate reserves, thus makes possible to distinguish three main layers: submittal, principal and basal. A characterization of the ore was carried out to determine the mineralogical and chemical characteristics. Thermal analysis, infrared and NMR techniques were used to study the thermal and structure behaviors of the organic matter in Moroccan phosphate from Bengurir. The TG analysis showed that the investigated mineral exhibited 7 mass% as total mass loss. The calcination-separation enrichment of carbonate-phosphorite ores from Bengurir region (Morocco) has been studied.
