Rock phosphate also referred to as phosphate rock or phosphorite, is a type of non-detrital sedimentary rock packed with phosphate mineralization, including apatite. Phosphate rock and Phosphorite, calcined. The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world. An estimated 1.5 trillion tons of…, …far the largest source is phosphate rock, although some use is made of phosphatic iron ore, from which the phosphorus is obtained as a by-product from the slag. Some phosphate rock is used to make calcium phosphate nutritional supplements for animals. This rock’s make up constitute various mending attributes that serve its carrier to reach a desired meditative state effortlessly. Phosphorites also form on stable areas associated with sandstone or shale. Our editors will review what you’ve submitted and determine whether to revise the article. Physical State & Appearance: Powder. Apatite includes 10 mineral species and has the general formula X 5 Y(PO 4) 3, where X … Coprolite: a. The Phosphoria Formation, for example, contains about 34 percent phosphorus pentoxide near the surface compared to only about 28 percent at depth. Phosphorite, also called phosphate rock, rock with a high concentration of phosphates in nodular or compact masses. (Holmes, 1928.) These deposits are not carbonaceous but do contain nodules and phosphatized shells. Is It an Organic Fertilizer? Naturally occurring calcium phosphate, Apatite, Phosphorite, Phosphate Rock. Written By Liz Oakes. Phosphorite, rock with a high concentration of phosphates in nodular or compact masses. Chemical Name: Calcium Phosphate. 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. Phosphosiderite... Strong Vibration Aids Healing And Spiritual Growth. 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. It is also important for the development of teeth and bones. The largest deposits are in North Africa (Morocco, Algeria, Tunisia), the United States (largely Florida),…. 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. Suppliers List, E-mail/RFQ Form, Molecular Structure, Weight, Formula, IUPAC, Synonyms for Phosphorite (CAS No. From an economic standpoint the manganese nodules (actually concretions of manganese dioxide) are more important. Premium Membership is now 50% off! Let us know if you have suggestions to improve this article (requires login). The phosphate content of phosphorite (or grade of phosphate rock) varies greatly, from 4% to 20% phosphorus pentoxide(P2O5). Phosphate rock is a general term referring to rock with high concentrations of phosphate minerals, most commonly those of the apatite family with the general formula Ca 5 (PO 4 CO 3) 3 (F,OH,Cl). 'Rock Phosphate' is a sedimentary rock composed of phosphate minerals high enough, especially apatite. Alteration of phosphorites tends to leach carbonates and sulfides and increase the percentage of phosphorus pentoxide.

Characterized by upgraded phosphorus content and reduced hydrocarbon levels." Significant deposits of phosphorites in the United States include the Phosphoria Formation in Idaho and the Monterey Formation in California. Phosphate mineral, any of a group of naturally occurring inorganic salts of phosphoric acid. As with potassium, there are extensive reserves. Characterized by upgraded phosphorus content and reduced hydrocarbon levels. Phosphates can be grouped as: primary phosphates that have crystallized from a liquid; secondary phosphates formed by the alteration of primary phosphates; and rock phosphates formed from phosphorous-bearing organic material. The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content. This article was most recently revised and updated by, https://www.britannica.com/science/phosphorite. 65996-94-3) Skype Phosphorite (CAS No. The phosphorite is usually carbonaceous and pelletal, and it is mixed with skeletal matter and phosphatic shells. 'Rock Phosphate' is a sedimentary rock composed of phosphate minerals high enough, especially apatite. Black Friday Sale! 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. Chemical Formula: Ca5(PO4)3. 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. 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. Nutrient Content: 32% Phosphate, 5% Calcium Carbonate. Characterized by upgraded phosphorus content and reduced hydrocarbon levels.
