Phosphoric acid and gypsum are prepared from phosphate rock by acidulating same with sulfuric acid or a mixture of sulfuric and phosphoric acids to form a slurry of CaSO4.1/2 H2O in phosphoric acid. The CaSO4.1/2 H2O is washed to remove adhered phosphoric acid and recrystallized from a solution containing phosphoric and sulfuric acids to form CaSO4.2H2O.
