  • Phosphorite - Wikipedia
    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% [1] to 20% phosphorus pentoxide (P 2 O 5)
  • Phosphorite : Properties, Composition, Uses, Deposits - Geology Science
    Phosphorite, also known as phosphate rock, is a type of sedimentary rock that is rich in phosphate minerals The main components of phosphorite include the minerals fluorapatite [Ca5 (PO4)3F] and hydroxyapatite [Ca5 (PO4)3OH], which are rich in phosphorus
  • Phosphorite | Definition, Formation, Uses | Britannica
    phosphorite, rock with a high concentration of phosphates in nodular or compact masses 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
  • Phosphorite: Mineral information, data and localities. - mindat. org
    The phosphate is usually present as carbonate-rich fluorapatite, typically in cryptocrystalline masses (grain sizes < 1 μm) (compare collophane) It may also be present as hydroxylapatite Please feel free to link to this page PROTHERO, D R SCHWAB, F (1996) Sedimentary Geology An Introduction to Sedimentary Rocks and Stratigraphy
  • Phosphate Rock - Minerals Education Coalition
    The term phosphate rock (or phosphorite) is used to denote any rock with high phosphorus content The largest and least expensive source of phosphorus is obtained by mining and concentrating phosphate rock from the numerous phosphate deposits of the world
  • Phosphorite - an overview | ScienceDirect Topics
    Phosphorite is a type of sedimentary rock that is the most significant source of phosphate rock globally It is primarily composed of carbonate-fluorapatite and forms in marine environments, often in shallow seas and along continental shelves, through the accumulation of phosphorus-rich materials from marine organisms
  • PHOSPHORITE
    Phosphorites are generally marine sedimentary rocks They range in age from Precambrian to Holocene In modern oceans, they tend to occur along the eastern margins of some ocean basins where deep-water upwelling occurs under areas of high biologic productivity
  • Phosphorite - PubChem
    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 Characterized by upgraded phosphorus content and reduced hydrocarbon levels
  • Phosphorites and High Phosphate Sedimentary Rocks
    Phosphorites and high phosphate rocks are rare sedimentary rocks But, when they are discovered, they are in layers of high concentration We can compare their present formation and distribution to Cenozoic distribution and use it as a guide toward finding the Flood post-Flood boundary
  • Phosphorite | EBSCO Research Starters
    Phosphorite, also known as phosphate rock, is a sedimentary rock that contains at least 50% phosphate minerals, primarily in the form of fluorapatite It is characterized by its high concentration of phosphorus, making it significantly richer in this element compared to typical sedimentary rocks
