Phosphate mineral - Wikipedia
Phosphate minerals contain the tetrahedrally coordinated phosphate (PO4 ) anion along sometimes with arsenate (AsO4 ) and vanadate (VO4 ) 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
Phosphate mineral, any of a group of naturally occurring inorganic salts of phosphoric acid, H 3 (PO 4 ). More than 200 species of phosphate minerals are recognized, and structurally they all have isolated (PO 4) tetrahedral units. Phosphates can be grouped as: (1) primary phosphates …
Phosphate Mineral - an overview | ScienceDirect Topics
The minerals from the apatite group only have petrogenic significance. Apatite (Ca 5 (F, Cl, OH) (PO 4) 3) is a group of phosphate minerals, usually referring to hydroxyapatite, fluorapatite, chlorapatite and bromapatite, named for high concentrations of OH −, F −, Cl − or Br − ions, respectively, in the crystal. Apatite is the main representative of isomorphic minerals of the apatite group that crystallizes in …
Which Minerals Include Phosphate?
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);
Phosphate Minerals - Soil Science at UW-Madison
Phosphate minerals comprise only a fractional percentage of the soil mass, perhaps averaging 0.02% or so, which impedes their direct identification by optical microscopy and x-ray analysis unless their concentration has been locally increased by addition of phosphate fertilizers.
Phosphate Mineral Group - Mineral Processing & Metallurgy
Phosphate Mineral Group. The Phosphate Mineral Group includes a number of the rarer minerals and apatite. Pitchblende or Uraninite is of Color, pitchy black, greenish, or brownish black; powder, brownish black, grayish, greenish; luster, dull and pitchy, sometimes slightly metallic. H = 5.5; G = 9 to 9.7; no cleavage; contains uranium, radium, etc.
Category:Phosphate minerals - Wikipedia
Phosphate minerals contain the phosphate, PO 43−, anion . In standard mineral classification systems (in both the Dana [1] and Strunz [2] systems) the phosphate class includes the arsenates, vanadates and the polyvanadates. Strunz includes the vanadates(V, VI) in the oxides class .
Mineral Gallery - the Phosphates Class
The Phosphate Class is made up of minerals with a basic stone unit of tetrahedral (AO4) groups with a negative three (-3) charge. The A can be either Phosphorus, Arsenic, Vanadium or Antimony. The A can be either Phosphorus, Arsenic, Vanadium or Antimony.
Mineral Resource of the Month: Phosphate Rock | EARTH Magazine
As a mineral resource, “phosphate rock” is defined as unprocessed ore and processed concentrates that contain some form of apatite, a group of calcium phosphate minerals that is the primary source for phosphorus in phosphate fertilizers, which are vital to agriculture.
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.
Phosphate Rock Statistics and Information - USGS
Phosphate rock minerals are the only significant global resources of phosphorus. The United States is the worlds leading producer and consumer of phosphate rock, which is used to manufacture phosphate fertilizers and industrial products.
Phosphate | Florida Department of Environmental Protection
Phosphate includes several naturally occurring minerals that contain phosphorus as well as other elements. It is primarily used to produce fertilizers for stone production. It may also be used in animal feed supplements, stone preservatives and many industrial products.

Phosphate Primer
We mine phosphate minerals. Phosphorus is highly reactive and is not found in its elemental form in nature. It occurs in nature as phosphate, which is a charged group of atoms, or an ion. It is made up of a phosphorus atom and four oxygen atoms (PO 4) and carries three negative charges.

phosphorite | Definition, Formation, & Uses | Britannica
Phosphorite, also called phosphate rock, 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.
