Example of phosphoric acid production. Wet process phosphoric acid is prepared by adding sulfuric acid (H 2 SO 4) to apatite or tricalcium phosphate rock resulting in the following reaction: . 3 H 2 SO 4 + Ca 3 (PO 4) 2 + 6 H 2 O ↔ 2 H 3 PO 4 + 3 CaSO 4 •2H 2 O . Wetprocess acid has to be purified by removing fluorine and other undesirable elements to produce feedgrade phosphoric acid.
