Detailed explanation-1: -The main source of phosphorus is sedimentary rock containing the calcium phosphate mineral apatite (a group of phosphate minerals). Phosphate rock is mined and either solubilized to produce phosphoric acid or smelted to produce elemental phosphorus.
Detailed explanation-2: -Phosphorus is obtained mainly from the minerals apatite and fluorapatite. It is mined mostly in the USA (Florida), Kazakhstan, China, Morocco, and Tunisia. Other phosphorus-bearing minerals include phosphophyllite, turquoise and vivianite.
Detailed explanation-3: -phosphate mineral, any of a group of naturally occurring inorganic salts of phosphoric acid, H3(PO4). More than 200 species of phosphate minerals are recognized, and structurally they all have isolated (PO4) tetrahedral units.
Detailed explanation-4: -Answer and Explanation: A phosphate mineral is made from phosphoric acid H3(PO4) producing a salt. Phosphate minerals have a unit of a phosphorus atom bonded to four oxygen atoms.
