en.wikipedia.org/wiki/Phosphate_mineralsPhosphate 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.
www.britannica.com/science/phosphate-mineralPhosphate 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.
en.wikipedia.org/wiki/Category:Phosphate_mineralsPhosphate 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.
www.sciencedirect.com/topics/earth-and-planetary-sciences/phosphate-mineralIn the phosphate minerals within this broad grouping, the main cations, which may be either monovalent, divalent, or trivalent, are coordinated to varying numbers of oxygen atoms to form polyhedra, which are then linked in various ways, commonly through (PO 4) tetrahedra, to form chains.Chains are then linked to form sheets, which stack in various crystallographic directions.
www.galleries.com/PhosphatesThe 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 ...
www.thoughtco.com/what-are-phosphate-minerals-4123032Apatite 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 ...
www.911metallurgist.com/blog/phosphate-minerals-groupThe 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. Found in pegmatite granite dikes, and also, in some cases, with ores ...
www.springer.com/gp/book/9783642617386Indeed, many pegmatitic phosphate minerals have acquired some notoriety because of the rarer trace metals which they tend to accumulate. With the commercialization of phosphate fertilizers since the early part of the 19th century, phosphate minerals have assumed an important role in industrial chemistry and agriculture.
soils.wisc.edu/facstaff/barak/temp/soil8510/notes/phosphates.htmlPhosphate 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.
www.rocksandminerals4u.com/phosphates.htmlPhosphates. The phosphate minerals contain phosphorus and oxygen in a 1:4 ratio. Written as PO 4 this compound combines with other elements to form phosphates.. The three mineral examples listed below are some of the more common members of this class.
