• Phosphate mineral - Wikipedia

    en.wikipedia.org/wiki/Phosphate_minerals Phosphate minerals contain the tetrahedrally coordinated phosphate (PO 4 3−) anion along sometimes with arsenate (AsO 4 3−) and vanadate (VO 4 3−) substitutions. Chlorine (Cl −), fluorine (F −), and hydroxide (OH −) anions that also fit into the crystal structure.. The phosphate class of minerals is a large and diverse group, however, only a few species are relatively common.
  • phosphate mineral | Description, Uses, & Facts | Britannica

    www.britannica.com/science/phosphate-mineral Phosphate mineral, any of a group of naturally occurring inorganic salts of phosphoric acid. 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.

    www.sciencedirect.com/topics/earth-and-planetary-sciences/phosphate-mineral The production of phosphate mineral fertilizers is one of the most profitable and financially stable among manufacturing industries. Phosphate ore (apatite) is converted into fertilizer with sulfuric acid and phosphogypsum is a by-product of this process. Approximately 5 tons per ton of P 2 O 5 is produced. Rock phosphate is a naturally occurring source for P 2 O 5.
  • Which Minerals Include Phosphate? - ThoughtCo

    www.thoughtco.com/what-are-phosphate-minerals-4123032 Apatite is a family of minerals centered around fluorapatite, or calcium phosphate with a bit of fluorine, with the formula Ca 5 (PO 4) 3 F. Other members of the apatite group have chlorine or hydroxyl that take the place of the fluorine; silicon, arsenic or vanadium replace the phosphorus (and carbonate replace the phosphate group); and strontium, lead, and other elements substitute for the ...
  • Mineral - Phosphates | Britannica

    www.britannica.com/science/mineral-chemical-compound/Phosphates Mineral - Mineral - Phosphates: Although this mineral class is large (with almost 700 known species), most of its members are quite rare. Apatite [Ca5(PO4)3(F, Cl, OH)], however, is one of the most important and abundant phosphates. The members of this group are characterized by tetrahedral anionic (PO4)3– complexes, which are analogous to the (SO4)2– groups of the sulfates.

    en.wikipedia.org/wiki/Category:Phosphate_minerals Phosphate minerals contain the phosphate, PO 4 3−, anion.. In standard mineral classification systems (in both the Dana and Strunz systems) the phosphate class includes the arsenates, vanadates and the polyvanadates. Strunz includes the vanadates(V, VI) in the oxides class.. Subcategories. This category has only the following subcategory.

    soils.wisc.edu/facstaff/barak/temp/soil8510/notes/phosphates.html Another phosphate mineral of some interest is struvite, NH 4 MgPO 4. That this ammonium salt is insoluble is somewhat surprising given that ammonium phosphates, both mono- and di, are quite soluble, as are most other ammonium salts. Because this mineral contains nitrogen, an element associated with biota, it is to be found in conjunction with ...

  • Mineral Gallery - the Phosphates Class

    www.galleries.com/Phosphates The Phosphate Class is made up of minerals with a basic chemical unit of tetrahedral (AO4) groups with a negative three (-3) charge.The A can be either Phosphorus, Arsenic, Vanadium or Antimony. The basic chemical unit can be combined with metal ions on a one to one ratio or usually in more complex combinations with other ions such as hydroxide groups (OH), uranyl groups (UO2), a halogen or ...
  • Phosphate Rock Statistics and Information

    www.usgs.gov/centers/nmic/phosphate-rock-statistics-and-information Phosphorus is an essential element for plant and animal nutrition. Most phosphorus is consumed as a principal component of nitrogen-phosphorus-potassium fertilizers used on food crops throughout the world. Phosphate rock minerals are the only significant global resources of phosphorus. The United States is the world's leading producer and consumer of phosphate rock, which is
