Apatite Wikipedia
Feb 13, 2019· Apatite is a family of minerals centered around fluorapatite, or calcium phosphate with a bit of fluorine, with the formula Ca 5 (PO 4) 3 F. Other members of the apatite group have chlorine or hydroxyl that take the place of the fluorine; silicon, arsenic or vanadium replace the phosphorus (and carbonate replace the phosphate group); and strontium, lead, and other .

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 OH − ion can be replaced by fluoride, chloride or carbonate ...
Apatite is the principal primary mineral, but a number of others are common in deposits formed during weathering of phosphate *In the trade the phosphate content of phosphate rock and fertilizer is commonly re ported as Ca3(PO4 >2, known as bone phosphate of lime (). To convert PjOs to
This concentrate is ground to 90 pct minus 75 µm and leached to dissolve the phosphate. Apatite, Ca5(PO4)3(F, Cl, ½CO3, OH), is the primary phosphate mineral in the phosphate rock. During leaching the apatite is solubilized as H3PO4 and the calcium content of the apatite is . process of phosphate apatite durbanlizards
