http://chemicalland21.com/industrialchem/inorganic/ROCK%20PHOSPHATE.htm Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide (P2O5). Marketed phosphate rock is enriched … See more (1) Pristine: Phosphates that are in pristine conditions have not undergone bioturbation. In other words, the word pristine is used when phosphatic sediment, phosphatized stromatolites and phosphate See more The heaviest accumulation of phosphorus is mainly on the ocean floor. Phosphorus accumulation occurs from atmospheric precipitation, dust, … See more Production Deposits which contain phosphate in quantity and concentration which are economic to mine as ore for their phosphate content are not particularly common. The two main sources for phosphate are guano, formed from See more Phosphates are known to be deposited in a wide range of depositional environments. Normally phosphates are deposited in very shallow, near-shore marine or low energy environments.

Phosphoric acid Definition, Formula, Uses, & Facts Britannica
The phosphate ion has a molar mass of 94.97 g/mol, and consists of a central phosphorus atom surrounded by four oxygen atoms in a tetrahedral arrangement. It is the conjugate base of the hydrogen phosphate ion H(PO 4) , which in turn is the conjugate base of the dihydrogen phosphate ion H 2(PO 4) , which in turn is the conjugate base of orthophosphoric acid, H 3PO 4. WebContext 1 ... phosphate rock material, grinded natural rocks, from Pogoni area of Ioannina, containing 14.43% of P 2 O 5 , was used. . The chemical analysis of the mineral used, was … WebAbstract. Phosphate rock and sulfuric acid are the two major raw materials for manufacture of phosphate fertilizers. Nearly all commercial phosphate fertilizers are derived from phosphate rock; the major exception is basic slag which derives its phosphorus indirectly from phosphate minerals that are present in iron ore or deliberately added to ... rawlinson renault bury st edmunds
