The production of triple superphosphate from raw apatite ore involves a complex series of reactions. These involve phosphoric acid, and also use sulfuric acid. Monocalcium phosphate is only one of the products of the process. Triple superphosphate is made by the reaction of fluorapatite with phosphoric acid in aqueous solution (Hoffmeister, 1993):
Ca10(PO4)]6F2 + 14 H3PO4 + 10 H2O 10Ca(H2PO4)2 • H2O + 2 HF
