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.
