  • 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% to 20% phosphorus pentoxide (P 2 O 5).Marketed phosphate rock is enriched ("beneficiated") to at least 28%, often more than 30% P 2 O

  • Phosphate mining in the United States - Wikipedia

    Three classes of phosphate deposits have been mined in central Tennessee; in order of decreasing importance: brown phosphate rock, blue phosphate rock, and white phosphate rock. [16] The most important phosphate deposits were the so-called brown phosphate rock, mined from Ordovician limestones , some parts of which are rich in phosphate.

  • limestone | Characteristics, Formation, Texture, Uses,

    Limestones enriched in phosphate by the chemical action of ocean waters constitute a principal source of raw materials for the fertilizer industry. When heated to temperatures of 900 to 1,000 °C (1,650 to 1,800 °F), limestones will dissociate calcium carbonate and yield carbon dioxide and lime, the latter having major applications in the,

  • KGS--Geological Log Analysis--The Gamma Ray Log

    The photograph shows a Geiger counter on an outcrop of the Heebner Shale at the corner of 17th Street and Bob White in Lawrence. The Heebner Shale is a "black shale," whose color is caused by organic matter content. Both the organic content and phosphate nodules in the Heebner Shale are hosts for uranium.

  • Apatite: Its uses as a mineral and gemstone

    Like limestone, phosphate rock is deposited in sedimentary basins where the influx of detrital material is relatively low. That allows the phosphate to accumulate with very little dilution from other materials. Where the dilution rate is high, phosphatic shales, mudstones, limestones, and sandstones will form instead of phosphate rock.

    Both limestones and shales contain multitudes of these animal shells. Reeflike Limestones and Shell Limestones--Many limestones contain the shells not only of crinoids and fusulinids, but also of corals, brachiopods, clams, oysters, bryozoans, and other forms. Some of the animals lived in colonies, and the remains formed lens-shaped or elongate,

    Jul 06, 2020· Florida Geological Survey_DEP Staff_Agatized Coral with Quartz.jpg In 1979 the Florida Legislature designated agatized coral as the Florida State Stone. It is described in the statute as a chalcedony pseudomorph after coral, appearing as limestone geodes lined with botryoidal agate or quartz crystals and drusy quartz fingers, indigenous to Florida.

  • Mineral Resources from the Ocean - building, river, sea,

    Limestones (rocks composed of calcium carbonate),Complex organic and inorganic processes constantly precipitate phosphate-rich crusts and granules in shallow marine environments. These are the analogs (comparative equivalents) of the onshore deposits being mined in several parts of the world, and represent future potential reserves if land,

  • 3.5: Non-Silicate Minerals - Geosciences LibreTexts

    Phosphates are an important ingredient of fertilizers as well as detergents, paint, and other products. The best known phosphate mineral is apatite, Ca 5 (PO 4) 3 (F,Cl,OH), variations of which are found in teeth and bones. The gemstone turquoise [CuAl 6 (PO 4) 4 (OH) 8 ·4H2O ] is a copper-rich phosphate mineral that, like gypsum, contains,
