Phosphoric acid - Essential Chemical Industry
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 (gypsum) plus other insoluble impurities. Water is added and the gypsum is removed by filtration along with ...
