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 Ca 10 (PO 4) 6 (OH,F,Cl) 2, and the crystal unit cell formulae of the individual minerals are written as Ca 10 (PO 4) 6

Hydroxyapatite Wikipedia

Hydroxyapatite, also called hydroxylapatite (HA), is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4) 3 (OH), but it is usually written Ca 10 (PO 4) 6 (OH) 2 to denote that the crystal unit cell comprises two entities. Hydroxyapatite is the hydroxyl endmember of the complex apatite group.The OH − ion can be replaced by fluoride, chloride or carbonate

A smaller density source, located within the shallow Precambrian basement, is partly coincident with the magnetic source at Pea Ridge. In contrast, the Boss models show a large (625-m-wide), vertically extensive, and coincident dense and magnetic stock with shallower adjacent lobes that extend more than 2,600 m across the shallow Precambrian

Selective flotation of apatite from iron oxides

Jan 01, 1992· For the microflotation tests, purified samples of apatite and hematite were prepared from selected phosphate ore samples from the Mr. Weld deposit by gravity concentration and magnetic separation. The apatite and hematite were determined to be 98.0% and 97.5% pure, respectively, by XRD and chemical analysis.

Apatite: Mineral information, data and localities.

"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. "Apatite" crystals are short to long hexagonal prisms [0001],

Apatite: The mineral apatite information and pictures

Apatite is named for the Greek word apate, which means "deceit", since Apatite is similar in appearance to many other minerals.Apatite describes a group of similar isomorphous hexagonal phosphate minerals. The primary Apatite group includes Fluorapatite, Chlorapatite, and Hydroxylapatite.The extended Apatite supergroup describes additional minerals such as Pyromorphite, Mimetite, and

Apatite saturation in basic to intermediate magmas

As SiO 2 concentration increases from 30 to 55 wt% at 1250°C, the amount of dissolved P 2 O 5 required to saturate a melt in apatite decreases from 12 to less than 4 wt%. At 1165°, the saturation level is uniformly ∼ 36% lower than at 1250°C.
