Overview

Geochemistry of phosphorus and the behavior of apatite

The concentration of phosphorus in glassy melt inclusions and rehomogenized nanogranitoids suggests a strong control of melt aluminosity on apatite solubility in peraluminous granites, which is consistent with existing experimental studies However, measured concentrations of phosphorus in melt inclusions and nanogranitoids are generally inconsistent with the concentrations expected from

phosphorus in apatite

Iron ore of high phosphorus content coexists with other minerals in the form of apatite or fluorapatite Phosphorus is spread on the edge of mineral particles of iron oxide and embedded in quartz or carbonate minerals and a small amount is present in the iron mineral grid ( Xia et al, 2011 ) phosphorus in apatite

Apatite Mineral | Physical Optical Properties

As a mineral, apatite is chiefly used as a phosphorus source for the manufacture of fertilizers One of the primary physical properties of apatite is that, in its mineral form, apatite is very stable and does not easily dissolve in a natural environment In their mineral forms, all apatite have the ability to absorb radioactive and metallic contaminants, and keep them locked This is one of

Phosphate Deposits USGS

Apatite is the principal primary mineral, but a number of others are common in deposits formed during weathering of phosphate *In the trade the phosphate content of phosphate rock and fertilizer is commonly re­ ported as Ca3(PO4 >2, known as bone phosphate of lime (BPL) To convert PjOs to

Export of Total, Particulate, and Apatite Phosphorus

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 watershed where sediments are dominated by allochthonous

Apatite: Its uses as a mineral and gemstone

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 mineral for a hardness of five in the Mohs Hardness Scale

Apatite | mineral | Britannica

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 found is clear, but it is fragile and difficult to cut and polish
