The gypsum precipitates and is filtered, giving phosphoric acid as the product. In a variation of the wet process - the hemihydrate process - calcium sulfate hemihydrate (CaSO 4•1H 2O) is produced as the precipitate. The present phosphoric-acid model simulates the production of phosphoric acid by the dihydrate process.
