  • Phosphoric Acid Production

    Phosphoric Acid Production

    In a wet process facility, phosphoric acid is produced by reacting sulfuric acid (H2SO4) with naturally occurring phosphate rock. The phosphate rock is dried, crushed, and then continuously fed into the reactor along with sulfuric acid. The reaction combines calcium from the phosphate rock with sulfate, forming calcium sulfate (CaSO4), commonly.
