The raw material for the production of P fertilizers is rock phosphate (apatite). Depending on their provenance, rock phosphates differ in fertilizer value. The solubility of apatites depends on the degree of isomorphic substitution of PO 4 3 − by CO 3 3 − and is higher the more phosphate is substituted by carbonate. While hard crystalline ...

"Apatite" is a field term for unidentified calcium phosphate members of the apatite group. Most "apatite" is fluorapatite, whereas hydroxylapatite is much less common and chlorapatite is very rare.
Phosphate rock needs processing to reduce the content of gangue minerals such as silicates, carbonates, and clays to meet the requirements of the phosphate industry.
Introduction Most rock phosphates (RPs) are apatite-bearing rocks that contain enough phosphorus (P) to be utilised for the manufacture of fertilisers, elemental P, and/or phosphoric acid (Gary et al. 1974).
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 …
Blue apatite is a prized mineral specimen by rock collectors for its vibrant royal blue color. Most of the apatite rock mined throughout the world is used to produce phosphate fertilizer. It is also used to produce animal feed supplements, phosphoric acid, elemental phosphorous, and phosphate compounds for the chemical industry.
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.
Earlier crystalline Apatite was extracted for phosphorous, however, nowadays massive deposits of Apatite-rich rock are used to extract phosphorous. Calcium hydroxylapatite along with some other phosphate minerals forms the inorganic constituent of the …
Apatite is also the stone associated with animal conservation, because it is composed of the mineral phosphate that makes up the teeth and bones of all vertebrate animals, as well as their horns, antlers or tusks. [Eason, 230] Blue Apatite Uses and Purposes - Overview. Blue Apatite is a motivational stone, promoting independence and ambitiousness.
leaching. Phosphate leached from guano phosphatizes the underlying rocks in some areas, forming apatite where the host rock is limestone and forming aluminum- or aluminum-iron-phosphate minerals where the underlying rock is a silicate. Individual deposits of both igneous apatite and marine phos
Apatite is the main source of phosphorus. Phosphorus was previously extracted from crystalline Apatite, but nowadays is extracted from enormous deposits of Apatite-rich rock. Apatite is essential in the manufacture of phosphate fertilizers, and is very important in …
Apatite definition is - any of a group of calcium phosphate minerals occurring in various colors as hexagonal crystals, as granular masses, or in fine-grained masses as the chief constituent of phosphate rock and of bones and teeth; especially : calcium phosphate fluoride.

Phosphorite, phosphate rock or rock phosphate is a non-detrital sedimentary rock which . main sources for phosphate are guano, formed from droppings, and rocks containing concentrations of the calcium phosphate mineral, apatite.
Apatite definition, a common mineral, calcium fluorophosphate, Ca5FP3O12, occurring in individual crystals and in masses and varying in color, formerly used in the manufacture of phosphate …
Characterization of phosphate rocks. Characterization studies of phosphate rock (PR) samples should provide data on: (i) the composition of the apatite, other phosphate minerals and gangue minerals; (ii) the relative amounts of mineral species present (estimated); and (iii) the particle size of the various minerals in the rock fabric, etc.
Apatite contains many minor and trace elements and can be used as an ore for rare earth elements. The largest apatite deposits are found in sedimentary rocks, but apatite also occurs in igneous and metamorphic rock. In sedimentary beds of phosphate rock, apatite occurs as a white or brownish earthy mass which must be detected by chemical tests.
A usually green, transparent mineral consisting mainly of calcium phosphate. Apatite occurs as hexagonal crystals in igneous, metamorphic, and sedimentary rocks, and is used as a source of phosphate for making fertilizers. It is the mineral used to represent a hardness of 5 on the Mohs scale.
Phosphate Rock. Phosphate Rock is an excellent natural source of phosphorus, calcium and many essential trace elements. It contains over 30 percent total phosphate (3-8 percent available) and 48 percent calcium (as CaO). Phosphate rock has approximately one fifth the neutralizing power of lime.
The two main sources for phosphate are guano, formed from droppings, and rocks containing concentrations of the calcium phosphate mineral, apatite. Phosphate rock is mined, beneficiated, and either solubilized to produce wet-process phosphoric acid, or smelted to produce elemental phosphorus.
