Rock phosphate minerals are called apatite (Greek for "deceiving"). As a group of minerals, its compositions are complex and not fully known. The general formula for apatite is M 10 (PO 4) 6 X 2, where M is commonly calcium but could also be Al or Fe.The X can be F –, OH –, Cl –, or CO 3 2–, resulting in fluor-, hydroxyl-, chloro-, and carbonate apatites.

8.4.3 Structure of Apatite Minerals. Natural phosphate minerals are mostly found as apatites, mainly as apatites of calcium. Because apatites are also found in bones, they have been studied extensively [16].A whole series of apatite structures can be derived from the formula M 5 (PO 4) 3 Z, where, M is a divalent metal and Z is an anion (OH −, Cl −, F −, and even CO 3 2 −).
