Which Minerals Include Phosphate? ThoughtCo
Reimphoto / Getty Images Apatite (Ca 5 (PO 4) 3 F) is a key part of the phosphorus cycle. It is widespread but uncommon in igneous and metamorphic rocks. Apatite is a family of minerals centered around fluorapatite, or calcium phosphate with a bit of fluorine, with the formula Ca 5 (PO 4) 3 F. Other members of the apatite group have A Brief History of Phosphorus. Around 1669, in his basement in Hamburg, Germany, Hennig Brand, one of the last alchemists, boiled down about 1,500 gallons of human urine in search of the Philosopher’s Stone. These alchemists believed this mystic stone could transmute any metal into gold. As the liquid turned to sludge, Brand made a The History and Future of Phosphorus IFDC

Traditionally, the United States, Russia, Morocco and China are the main exporters of phosphate rock. However, with the development of the phosphorus resources in North Africa and the Middle East, coupled with the continuous reduction of phosphate resources in traditional supply areas, North Africa and the Middle East have gradually As phosphate rock is a finite resource and global production is rising fast, several studies have warned that a maximum phosphorus production could be reached within a foreseeable future (Déry and Anderson, 2007, Rosemarin et al., 2009, Cordell et al., 2009, Mórrígan, 2010, Mohr and Evans, 2013).Phosphate rock production and depletion: Regional

11.21 Phosphate Rock Processing US EPA
11.21 Phosphate Rock Processing 11.21.1 Process Description1-5 The separation of phosphate rock from impurities and nonphosphate materials for use in fertilizer manufacture consists of beneficiation, drying or calcining at some operations, and grinding. The Standard Industrial Classification (SIC) code for phosphate rock processing is 1475. Phosphate rock (PR) is an important mineral resource with numerous uses and applications in agriculture and the environment. PR is used in the manufacture of detergents, animal feed, and phosphate (PO43–) fertilizers. Leaching or runoff losses from PR products like PO43– fertilizers, animal feeds, and detergents could cause Phosphate rock: origin, importance, environmental impacts,
