Phosphate Minerals - an overview | ScienceDirect Topics

Phosphate rock (phosphorite or rock phosphate) contains 15–20% phosphate bearing minerals. The phosphorus is present as fluorapatite—Ca 5 (PO 4) 3 F—or as hydroxyapatite (apatite)—Ca 5 (PO 4) 3 OH. Another source is dissolved phosphate minerals from igneous and metamorphic rocks. Phosphate rock is a nonrenewable resource that takes 10 ...
