Phosphate Rock is the raw material to manufacture most commercial phosphate fertilizers. In its unprocessed state, phosphate rock is not suitable for direct application. The process begins by grinding rock phosphate to a fine material. Potash is also fed together with super phosphate to obtain various grades of fertilizers.

Phosphate rock (PR) is an abundant ore and represents the basic raw material for the phosphatic fertilizer industry. Prior to industrial processing, PR is concentrated by grindingandscreening to separate a fine fraction that is very poor in P2O5. This fine fraction is a solid waste and represents a disposal problem. The present study shows that the fine fraction of groundandscreened
