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.
