Apatite is one of a few minerals produced and used by biological micro-environmental systems. Apatite is the defining mineral for 5 on the Mohs scale. Hydroxyapatite, also known as hydroxylapatite, is the major component of tooth enamel and bone mineral.

Fluorapatite is found in the teeth of sharks and other fishes in varying concentrations. It is also present in human teeth that have been exposed to fluoride ions, for example, through water fluoridation or by using fluoride-containing toothpaste. The presence of fluorapatite helps prevent tooth decay or

A stone of the Throat Chakra, Blue Apatite helps with public speaking and enhances group communication. Attuned to the Third Eye, it also improves concentration and memory skills, and is a good crystal for study purposes. It aids in time management when working on projects. Blue Apatite energetically acts as a hunger suppressant.

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.
Gravity Concentration Gravity concentration processes rely on the principal that gold contained within an ore body is higher in specific gravity than the host rocks that contain the gold . Elemental gold has a specific gravity of 19.3, and typical ore has a specific gravity of about 2.6. All gravity concentration devices create movement

Principles of gravity concentration Gravity concentration methods separate minerals of different specific gravity by their relative move- ment in response to gravity and one or more other forces, the latter often being the resistance to motion offered by a viscous fluid, such as water or air.
Early Use and Development of Gravity Concentration Gravity concentration of heavy minerals is a natural geological process, and Mother Nature has concen-trated minerals, such as gold, cassiterite, ilmenite, and diamonds, into natural placer (alluvial or glacial) deposits. Humans have used gravity concentration processes for thousands of years.
The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue. Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products. Most gold ores, however, only require separation into two parts—the
Chromite was beneficiated by gravity concentration and electrostatic separation This concentrate contained approximately 45% to 55% chromite, 40% to 50% olivine, and 5% to 10% calcium, magnesium, and iron silicat SEM examination of the sample show that the minerals were liberated Chemical analyses of all three materials are shown in table 1

When graphite is in high enough concentrations, these rocks can be mined, crushed to a particle size that liberates the graphite flakes, and processed by specific gravity separation or froth flotation to remove the low-density graphite. apatite flotation gangue minerals biotite hornblend.
"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.
[Hall, 63] Attuned to the Third Eye, it also improves concentration and memory skills, and is a good crystal for study purposes. It aids in time management when working on projects. [Eason, 230] Blue Apatite is particularly supportive for business consultants, and account or investment managers.
The hardness of Apatite is 5 in the Mohs scale (main test for apatite) and the specific gravity is 3.1-3.2. Apatites can be easily distinguished by their color, hardness, crystal form and can be scratched by a steel blade. Apatite dissolves in hydrochloric acid and attains a fluorescent orangish-yellow color after heating in long wave UV light.

Abstract. This book is devoted to gravity concentration technology for over a half a century. It provides coverage of the entire subject and contains information on both new and classical methods of gravity concentration.
Apatite incorporates variable and significant amounts of halogens (mainly F and Cl) in its crystal structure, which can be used to determine the initial F and Cl concentrations of magmas. The amount of chlorine in the apatite lattice also exerts an important compositional control
