It is used as a raw material in the manufacture of inorganic phosphorus fertilizers and can be used as organic phosphorus fertilizers when applied directly to the soil. The phosphates may be derived from a variety of sources, including marine invertebrates that secrete shells of calcium phosphate, and the bones and excrement of vertebrates. . In such ground phosphate rock (formula Ca 3 (PO 4) 2) are converted to dihydrogen. The reaction is completed in the belt conveyor: The reacted mass is then sent to a curing shed where the product is stored for 3 to 4 weeks for curing and drying. The chemical formula of Phosphate is PO43-. It contains over 30 percent total phosphate (3-8 percent available) and 48 percent calcium (as CaO). FEECO has been a leader in the fertilizer industry since 1951. The phosphorous content in these rocks is mainly derived from the presence of apatite minerals. The most predominant mineral of phosphate is francolite which is calcium carbonate-fluorapatite of formula [Ca 5 (PO 4 ,CO 3) 3 (F,OH)]. Phosphate rock is a general term for phosphate minerals that can be used economically, and is an important chemical mineral raw material. It is also important for the development of teeth and bones. Molecular Formula: Ca 5 FO 12 P 3: Synonyms: Fluorapatite. The United States is the world's leading producer and consumer of phosphate rock, which is used to manufacture phosphate fertilizers and industrial products. It has a molecular mass of 94.9714 g/mol and is a polyatomic ion. Phosphate can form many polymeric ions such as pyrophosphate, (P 2O 7)4 , and triphosphate, (P 3O 10)5 . The various metaphosphate ions (which are usually long linear polymers) have an empirical formula of (PO 3) and are found in many compounds. It is also called a phosphate group. Phosphate rock + Nitric acid Phosphoric acid + Calcium nitrate + Hydrofluoric acid. Phosphate Rock (Fertilizer) 'rock phosphate' is a sedimentary rock composed of phosphate minerals high enough, especially apatite.
