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.

· Apatite (Ca 5 (PO 4) 3 F) is a key part of the phosphorus cycle. It is widespread but uncommon in igneous and metamorphic rocks. 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

Rock phosphate is a natural mineral found as a geological deposit on a large scale in the form of sedimentary rocks containing various amounts of calcium phosphates. Once ground, it is used as a phosphatic fertilizer, called phosphorite or mineral phosphate, or as a primary source of phosphorus. Rock phosphate deposits are found in many

Beneficiation is the technical term describing the industrial process of mechanically separating minerals from each other. No chemical changes to the minerals are made at this point in the mining process.
