Apatite enrichment by rare earth elements: A review of

Mar 01, 2019  There are two processes of REE enrichment within apatite, the first is the substitution of REE 3+ and Na + for Ca 2+ within the apatite, the second is P 5+ substituted with REE 3+ and Si 4+ [ 39 ]. The end member of the second substitution is britholite, a mineral heavily enriched in REE [ 40 ].

The Versatile Apatite Mineral Group - Advancing Mining

Apatite has a high fluoride content and is a source of fluoride additives used in the United States. In the geological world, apatite is used for fission track dating, a technique that determines the age of a mineral sample by its uranium content. Apatite contains many minor and trace elements and can be used as an ore for rare earth elements.

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.

Introduction. Apatite [Ca 5 (PO 4) 3 (OH,F,Cl)] is a common accessory mineral in igneous, metamorphic and sedimentary rocks and an important REE bearer. Its atomic arrangement allows the incorporation of diverse elements in the structure such as S, Fe, Mn, Sr, Ba, Pb, Si, Na, Th, U and REE (the lanthanides plus Y). These elements occupy the Ca sites or replace P in the PO 4 tetrahedron.
