Phosphate Rock an overview ScienceDirect Topics

Allen V. Barker, in Encyclopedia of Analytical Science (Third Edition), 2019 Rock phosphate. Rock phosphate is a naturally occurring ore of marine sedimentary origin. It may have a composition of 0-30-0, but the grade is noted as 0-3-0, since rock phosphate is sparingly soluble and little of the phosphorus is available to crops.

Abstract. Phosphate rock (PR) is a finite mineral indispensable for fertilizer production, while P (phosphorus) is a major pollutant if applied or discharged in excess, causing widespread eutrophication (Carpenter and Bennet, 2011). High-grade PR is obtained from deposits which took millions of years to form and which are gradually being depleted.
