The manufacture of phosphoric acid is conventionally performed on a commercial scale by either the wet process or the thermal process. In the wet process, phosphate rock is treated with sulfuric acid to produce weak aqueous phosphoric acid (20 30% P 2 O 5) and calcium sulfate.

The wet-process phosphoric acid (WPPA) production is generally based on the use of sulfuric acid (H 2 SO 4) for phosphate ore attack. One of the main issues encountered in this process is related to the uncontrolled formation of mineral deposits at sensitive steps. In the generated complex aqueous systems, the dissolved species and the resulting physicochemical interactions are closely ...
