natural hydrophilic [2, 7, 8]. These minerals can be successfully separated from the oxide and silicate minerals by flotation process. However, based on the results from litera-ture, it can be said that it is difficult to de-termine the conditions of mutual separation of salt-type minerals (e.g. apatite from cal-cite) of flotation process.

Apatite is found in Myanmar (Burma), Brazil, India, Kenya, Madagascar, Norway, Sri Lanka, South Africa, Mexico, Canada and the United States. There are three minerals that actually contribute to apatite, which is the reason for the varied colors and shades of this stone. Apatite is calcium phosphate combined with fluorine, chlorine or hydroxyl.

oxide with apatite and fine grind of about 150 micron would be required for nearly complete liberation. Results & Discussion The mineral & chemical analyses implies that the approach should be to develop a process to reduce both iron & silica substantially to improve the apatite content after grinding to a fine size for better liberation.

According to Chaikina M.V., in the mechanical activation process, apatite decomposes into amorphous trisubstituted calcium phosphate - α-Ca 3 (PO 4) 2 (high-temperature form of tricalcium phosphate) and fluorite. Apatite melting temperature is 1900K, and α-tricalcium phosphate melting temperature is 2050K.

Apatite is not a single mineral but a group of phosphate based minerals that includes hydroxylapatite, fluorapatite and chlorapatite. Fluorapatite is by far the most common variety and can be found as both hexagonal crystals in many colors and massive forms. The stone from Madagascar generally referred to as "Blue Apatite" is a massive form of fluorapatite.

Apatite is "any group of calcium phosphate minerals occurring variously as hexagonal crystals, as granular masseor in fine-grained masses as the chief constituent of phosphate rock and of bones and teeth; especially: calcium phosphate fluoride," according to Merriam-Webster's dictionary. It is a common phosphate mineral.

This indicates that the silanol groups formed on the silicones by the present method can induce the apatite nucleation in 1.5 SBF and hence, apatite-coated silicones can be fabricated by a biomimetic process. Apatite–silicone composites thus prepared could exhibit mechanical properties analogous to the natural bone as well as bioactivity.

Since apatite is the dominant phosphate-containing mineral in the waste materials, a study was conducted using research-grade apatite, devoid of any ancillary clays and minerals. Using the crystalline apatite in the acid-alcohol leaching tests provided evidence as to why the extractions are incomplete.

APATITE BACKGROUND INFORMATION. Apatite is the name given to a group of three related minerals the most common of which is fluorapatite(Ca 5 (PO 4) 3 F), and more rarely clorapatite(Ca 5 (PO 4) 3 Cl) and hydroxylapatite(Ca 5 (PO 4) 3 OH). A complete solid solution series exists between these three with F, Cl and OH substituting for each other.
