What is Apatite? Apatite is the name of a group of phosphate minerals with similar chemical compositions and physical properties. They are an important constituent of phosphorite, a rock mined for its phosphorus content and used to make fertilizers, acids, and chemicals. Apatite has a relatively consistent hardness and serves as the index …
Apatite: Apatite, any member of a series of phosphate minerals, the world's major source of phosphorus, found as variously coloured glassy crystals, masses, or nodules. If not for its softness (Mohs hardness 5, compared with the 7 to 9 of most gems), apatite would be a popular gemstone; much of the material

Thus phosphate minerals, in which phosphorus is oxidized in the phosphate group, PO 4, are part of a tight geochemical cycle that includes the biosphere, rather like the carbon cycle. Apatite (Ca 5 (PO 4 ) 3 F) is a key part of the phosphorus cycle.
White phosphorus is the most dangerous form of phosphorus that is known to us. When white phosphorus occurs in nature this can be a serious danger to our health. White phosphorus is extremely poisonous and in many cases exposure to it will be fatal.

Phosphorous Content Of Apatite Apatite - Phosphate Minerals 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.
About 550 different minerals have been found to contain phosphorus, but, of these, the principal source of phosphorus is the apatite series in which calcium ions exist along with phosphate ions and variable amounts of fluoride, chloride, or hydroxide ions, according to the formula [Ca 10 (PO 4) 6 (F, Cl, or OH) 2].
The primary use of apatite is in the manufacture of fertilizer – it is a source of phosphorus. It is occasionally used as a gemstone. Green and blue varieties, in finely divided form, are pigments with excellent covering power.
An important source is phosphate rock, which contains the apatite minerals and is found in large quantities in the USA and elsewhere. There are fears that 'peak phosphorus' will occur around 2050, after which our sources will dwindle. ...

In mid-stage soils, the reservoir of primary apatite is diminished; less-soluble secondary minerals and organic phosphorus make up an increasing fraction of soil phosphorus. Late in soil development, phosphorus is partitioned mainly between refractory minerals and organic phosphorus ( Figure 2 ).

In real life, Phosphorus is almost never found freely in nature; except for minerals such as apatite. Phosphorus is found organically in sources of bone ash and guano and is also produced in supernovae as a byproduct of supernova nucleosynthesis, where the phosphorus-to-iron ratio from the supernova remnant is believed to be 100 times …

Apatite is the most common phosphate mineral, and is the main source of the phosphorus required by plants. The bones and teeth of most animals, including humans, are composed of calcium phosphate, which is the same material as Apatite.
Concentrations of apatite phosphorus (P) have been shown to be greater in the soils of agricultural and disturbed watersheds than in soils of forested watersheds. This observation suggests that changes in the relative concentration of apatite P in the sedimentary record of lakes might be a useful marker for land use changes in the …
