  • Phosphate rock or phosphorite is a general description applied to several kinds of rock which contain significant concentrations of phosphate minerals.
  • The two main sources for phosphate are guano, formed from bird droppings, and rocks containing concentrations of the calcium phosphate mineral, apatite.
  • Phosphate rock can be any rock or sediment with sufficiently high concentrations of some form of the mineral fluorapatite.
  • Phosphorus-rich rock is deposited in a body of water in which there is no oxygen; this is called an anaerobic environment.
  • Phosphate rock occurrence ranges from nodular, residual phosphatic limestone, to vein phosphates, and consolidated and unconsolidated
    phosphatic sediments.
  • Phosphate rock is mined, beneficiated, and either solubilized to produce wet-process phosphoric acid, or smelted to produce elemental phosphoric acid or smelted to produce elemental phosphorus.
  • Phosphate rock is formed in oceans in the form of calcium phosphate, called phosphorite.
  • The phosphatic rock is characterised by filaments of wavellite, turquoise and quartz.
  • The effectiveness of PR is largely determined by the extent of PR dissolution in moist soil.
  • 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.
  • A green house experiment was carried out on a simulated crop rotation system of upland rice-soybeanmungbean to determine the effect of P-derived from different phosphate rock (PR) sources and TSP using 32P.
  • Commercial phosphate rock is usually sedimentary in origin and is used primarily as a plant nutrient.
  • Several scientists the world over have been trying to develop1,2 low-cost phosphatic fertilizers.
  • Indian scientists were successful in testing low-grade phosphate rocks3–5 for direct application.
    Nitrates and phosphates are the main agronutrients mined by current sub-Saharan small scale agricultural practices.
  • Biofertilisers produced with phosphate rock (PR) plus sulphur (S) inoculated with Acidithiobacillus can promote plant growth and increase available P in tropical soils.
  • Deflourinated phosphate rock is the source of phosphate used in animal feed and feed concentrates.
  • Technically and economically feasible beneficiation technology is used for processing dolomite pebbles which is needed to recover phosphate value.
  • The Florida phosphate industry has been practicing the current flotation technique for concentrating phosphate minerals for half a century.
  • Flotation is one of the most efficient techniques applied for phosphate upgrading. Desliming of flotation feed is a critical pre-request step for successful phosphate/gangue separation by flotation.
  • Researches on their structures by means of XRD, IR and EPR technique revealed that their crystal structures changed considerably, improving their activity and preventing the fixation of available phosphorus in the soil, and consequently, greatly improved the bioavailability and became the main cause of the increase of biomass.
  • The United States is the world's leading producer and consumer of phosphate rock.
  • China, the United States and Morocco are the world's largest miners of phosphate rock.
    Most of the U.S. and world phosphate rock resources are widely distributed marine phosphorite deposits.
  • Total capacity of the phosphate rock industry in the U.S. is 56 million tons, with mines currently operating at about 90 percent of capacity.
  • There are markets such as those of Malaysia and Brazil, where directly applied phosphate rock makes good sense from an agronomic or economic point of view.
