Phosphoric acid – Manufacturing process for Phosphoric acid

The insoluble gypsum is separated from the reaction solution by filtration. The operating conditions are generally selected so that the calcium sulfate will be precipitated in either the dihydrate or the hemihydrate form, thus producing 26-32% P2O5 at 70-80C for dihydrate precipitation and 40-52% P2O5 at 90-110C for hemihydrate precipitation.
