Phosphoric acid description, application and process ...

Acid produced by the 'wet' route is less pure but is used in the manufacture of fertilizers. (a) Wet process. Phosphoric acid is produced from fluorapatite, known as phosphate rock, 3Ca 3 (PO 4) 2.CaF 2, by the addition of concentrated (93%) sulfuric acid in a series of well-stirred reactors. This results in phosphoric acid and calcium sulfate ...
