The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. Phosphite(3-) is a trivalent inorganic anion obtained by removal of all three protons from phosphorous acid.It is a trivalent inorganic anion and a phosphite ion. Characterized by upgraded phosphorus content and reduced hydrocarbon levels." The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. In the past, rock phosphate was used alone as a fertilizer, but due to a lack in supply, as well as low concentration, most applied fertilizer is processed. Coprolite: a. Our editors will review what you’ve submitted and determine whether to revise the article.

'Rock Phosphate' is a sedimentary rock composed of phosphate minerals high enough, especially apatite. Phosphate rock and Phosphorite, calcined. Is It an Organic Fertilizer? Let us know if you have suggestions to improve this article (requires login). Characterized by upgraded phosphorus content and reduced hydrocarbon levels. Phosphate mineral, any of a group of naturally occurring inorganic salts of phosphoric acid. Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock that contains high amounts of phosphate minerals. Some description was translated by software and the data is only as a reference. This rock’s make up constitute various mending attributes that serve its carrier to reach a desired meditative state effortlessly. Characterized by upgraded phosphorus content and reduced hydrocarbon levels. Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P2O5. Apatite includes 10 mineral species and has the general formula X 5 Y(PO 4) 3, where X … Phosphosiderite... Strong Vibration Aids Healing And Spiritual Growth. Major deposits also occur in the Sechura Desert in Peru. Omissions? The fossil excrement of fishes, reptiles, and mammals. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. By comparison, the average phosphorus content of sedimentar… Significant deposits of phosphorites in the United States include the Phosphoria Formation in Idaho and the Monterey Formation in California. The Phosphoria Formation, for example, contains about 34 percent phosphorus pentoxide near the surface compared to only about 28 percent at depth. Country Of Origin: Christmas Island 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. 65996-94-3) Skype Phosphorite (CAS No. This article was most recently revised and updated by, https://www.britannica.com/science/phosphorite. These nodules are found in a variety of physical forms, but the average size is about 3 cm (1.2 inches). 65996-94-3) Suppliers Phosphosiderite is a jewel boulder of desire that coincide the mending attributes of both the minerals, so as to help its carrier to sense the connection of his vitalities, energies with the energies of the cosmos. In addition to being an essential organic source of phosphorus, phosphate rock also contains limestone, clay, and some other essential trace minerals . Nevertheless, three principal types exist: (1) regionally extensive, crystalline nodular, and bedded phosphorites, (2) localized concentrations of phosphate-rich…, …(but not yet exploited) are phosphorite and manganese nodules. Phosphorite, also called phosphate rock, rock with a high concentration of phosphates in nodular or compact masses. Substance obtained by heating naturally occurring phosphate rock to 732°C to 816°C (1350°F to 1500°F) in a fluidized bed or other suitable device for oxidizing carbonaceous matter. Alteration of phosphorites tends to leach carbonates and sulfides and increase the percentage of phosphorus pentoxide. Naturally occurring calcium phosphate, Apatite, Phosphorite, Phosphate Rock. This occurs through washing, screening, de-liming, magnetic separation or flotation. From an economic standpoint the manganese nodules (actually concretions of manganese dioxide) are more important. Many sedimentary rocks contain phosphate in the form of scattered bones composed of the mineral apatite (calcium phosphate), but rocks composed predominantly of phosphate are rare. Updates? The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. Written By Liz Oakes. "TSCA Definition 2008: Substance obtained by heating naturally occurring phosphate rock to 732.degree.C to 816.degree.C (1350.degree.F to 1500.degree.F) in a fluidized bed or other suitable device for oxidizing carbonaceous matter. Rock phosphate, or phosphorite, is mined from clay deposits that contain phosphorus and is used to make organic phosphate fertilizers that many gardeners utilize. The largest deposits are in North Africa (Morocco, Algeria, Tunisia), the United States (largely Florida),…. Chemical Formula: Ca5(PO4)3. 'Rock Phosphate' is a sedimentary rock composed of phosphate minerals high enough, especially apatite. Apatite includes 10 mineral species and has the general formula X 5 Y(PO 4) 3, where X … Suppliers List, E-mail/RFQ Form, Molecular Structure, Weight, Formula, IUPAC, Synonyms for Phosphorite (CAS No. phosphorite;phosphate rock,physical properties,suppliers,CAS,MSDS,structure,Molecular Formula, Molecular Weight ,Solubility,boiling point, melting point Some phosphate rock is used to make calcium phosphate nutritional supplements for animals. Deposits may be up to one metre (about 3 feet) thick. Premium Membership is now 50% off! Phosphosiderite has a lovely calming, soothing vibration that aids stress and anxiety, but that is not all there is to it, as it is a healing stone that will resonate within all of the chakras. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Phosphate rock of 70 to 75% BPL, or as high as is reasonably obtainable, is finely ground in a ball mill and then mixed with cooled recycled phosphoric acid-gypsum slurry in a digestion tank (Figs. Rock phosphate also referred to as phosphate rock or phosphorite, is a type of non-detrital sedimentary rock packed with phosphate mineralization, including apatite. phosphorite;phosphate rock,physical properties,suppliers,CAS,MSDS,structure,Molecular Formula, Molecular Weight ,Solubility,boiling point, melting point Nutrient Content: 32% Phosphate, 5% Calcium Carbonate. Chemical Name: Calcium Phosphate. Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. These deposits are not carbonaceous but do contain nodules and phosphatized shells. Typical phosphorite beds contain about 30 percent phosphorous pentoxide (P2O5) and constitute the primary source of raw materials for most of world’s production of phosphate fertilizers. Phosphorites also form on stable areas associated with sandstone or shale. Some phosphate rock is used to make calcium phosphate nutritional supplements for animals. It is used directly in fertilizer and as a source of phosphorous compounds. The thickest deposits of phosphorite form in areas characterized by carbonaceous shale and chert. Ninety percent of phosphate mined is used to produce chemical fertilisers. (Holmes, 1928.) 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.
