Phosphorus and Phosphates | SpringerLink
Phosphates, compounds of the element phosphorus, are produced from relatively abundant supplies of phosphate rock. The major use of phosphate is to supply phosphorus, one of the three essential plant foods—nitrogen, phosphorus, and potassium. Phosphate rock extraction from its ore, and its subsequent conversion into fertilizer …

Phosphate rock normally is used as a dry rock or in slurry form. However, in some cases, particularly where the raw phosphate is high in carbonaceous matter or it is desirable to have a clean acid, the rock is calcined. Also, in a few cases, the phosphate rock is calcined, the product slaked, and free lime separated as a beneficiation step.
