Recent revisions of phosphate rock reserves and resources: A
Phosphate rock (PR) is a finite mineral indispensable for fertilizer production, while P codes use the term “ore reserves” and prescribe, in the con-text of coal,There is a clear and pressing need to better manage our planet's resources. Phosphorus is a crucial element for life, but the natural phosphorus cycle has been perturbed to such an extent that humanity faces two dovetailing problems: the dwindling supply of phosphate rock as a resource, and the overabundance of phosphate in water systems leading to Phosphorus recovery and recycling closing the loop

Phosphate rock. Turquoise in graphitic slate from Black Range near Cheshunt, Victoria (Scale: 8 cm) Phosphate rock is a general term used to describe natural mineral assemblages of variable composition that have a high concentration of phosphate minerals. Most of the minerals in phosphate rock belong to the apatite group.Phosphorus is too reactive to be found in nature in its elemental state. In particular, white phosphorus is reactive with oxygen, and phosphorus is most commonly found in its highest formal oxidation state (+5), as in phosphate (PO 43−) salts or in organophosphorus compounds.

Depending on its source this cargo may have flow characteristic, but once settled it The use of reactive rock phosphate (RP) in acidic soils as a phosphate (P) source for pastures and crops presents attractive economic advantages with respect to soluble phosphate. However, some studies have demonstrated that the short-term (1-year) efficiency of RP, compared with that of water-soluble P, is relatively poor. This fact Improving the short-term efficiency of rock phosphate-based fertilizers
