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 eutrophiion (Carpenter and Bennet, 2011). Highgrade PR is obtained from deposits which took millions of years to form and which are gradually being depleted. Recently, global PR reserves as reported by the US ...

Their estimates often use United States Geological Survey (USGS) data on total world reserves, but each year, USGS estimates change, usually to expand reserves, and sometimes dramatically. The largest discoveries as of late are in Morocco or the Western Sahara, and there is as of yet no definitive world total of highgrade phosphate deposits. By determining the actual amount of phosphorus ...

Phosphate rocks, also referred to as phosphorites, are sedimentary deposits with high phosphorus (P) concentrations. These rocks are one of the primary ore sources for P (Fig. 1), which in turn is a critical and nonrenewable element for fertilizer production, upon which global fertility depends. The startling limitation of phosphate rock reserves has led to a renewed intensity of research ...

· Phosphate rock (PR) is among the 5th most mined materials on earth (approx. 250 million t per year) and often shows elevated concentrations of REE (Emsbo et al., 2015, USGS, 2021). Morocco is the second largest producer of PR (36 million t in 2019), with the by far largest phosphate deposits in the world (50 billion t or > 70% of currently known global P reserves ( USGS, 2020 )).
