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 minerals were raw phosphorite ores produced in Kaiyang Phosphate Mine, Guizhou Province, China. For single minerals, after removing impurities by hands, breaking with a ceramic jaw crusher, and grinding by a ceramic ball mill, the samples with a particle size less than 25 μm were screened for testing.

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.

A large apatite-iron tailings deposit is located north of Sweden in Kiruna and Malmberget, containing a substantial amount of P 2 O 5 (4–8%) from the previous magnetite recovery. Efforts are being made to ensure the efficient extraction of the minerals of interest with a minimum CO 2 footprint.

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.

Fine grinding of the phosphate feed will naturally tend to liberate the carbonates from the pockets of apatite matrix. But the problems related to handling, filtration and marketing of fine phosphates may not allow grinding to exceed a certain limit. On the other hand, higher energy for grinding may cause an extra cost to the process.

Dissolution of Apatite and Dolomite. Apatite and dolomite are slightly soluble minerals, which can release the dissolved Ca 2+ and Mg 2+ to affect the surface electrical behaviors of minerals.
