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 ].

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.

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.
MoreNov 11, 2014 Apatite is the generic name, which was first introduced by German geologist A.G. Werner. These minerals and their synthetic analogs represent a major class of ionic compounds and the most common crystalline form of calcium phosphates, which are of interest of many industrial branches and scientific disciplines. Since, apatite (fluorapatite) is the most abundant phosphate mineral,

An important component of phosphorite (phosphate rock) is carbonate apatite, as it is required for phosphorous fertilizer production due to its increased phosphate solubility caused by carbonate substitution in the apatite mineral lattice. High phosphate concentrations in municipal wastewater treatment plants are commonly reduced by precipitating iron phosphate by addition of iron chloride.

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.

Calcium phosphate apatites are inorganic compounds encountered in many different mineralized tissues. Bone mineral, for example, is constituted of nanocrystalline nonstoichiometric apatite, and the production of “analogs” through a variety of methods is frequently reported. In another context, the ability of solid surfaces to favor the nucleation and growth of #x201c;bone-like#x201d ...

Aug 28, 2012 The structure of bone stems from a tightly controlled process whereby collagen fibrils secreted by osteoblasts are progressively mineralized by poorly crystalline carbonated apatite. The process that precedes mineral’s eventual propagation on the extracellular matrix (ECM), however, remains largely unexplained and is highly controversial.
