Apatite - Wikipedia

Apatite is a group of phosphate minerals, usually referring to hydroxyapatite, fluorapatite and chlorapatite, with high concentrations of OH , F and Cl ions, respectively, in the crystal. The formula of the admixture of the three most common endmembers is written as Ca10(PO4)6(OH,F,Cl)2, and the crystal unit cell formulae of the individual minerals are written as Ca10(PO4)6(OH)2, Ca10(PO4)6F2 and Ca10(PO4)6Cl2. The mineral was named apatite by the German geologist Abraham Gottlob W

Beneficiation - an overview ScienceDirect Topics

Apatite is accompanied by minor amounts of other REE phases, such as cheralite, monazite, parasite, synchysite, bastnaesite, and xenotime. Apatite typically occurs as idio- to hypidimorphic grains varying from 0.1 to 4.0 mm in diameter. • The whole rock REE concentration was determined to be 8.3% for the apatite vein material.

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.
