Phosphoric acid, H 3 PO 4, is produced from phosphate rock by wet process or thermal process. 80% of the world's phosphoric acid is obtained by the wet process. The wet process consists of reaction, filtration and concentration steps. The phosphate rock is ground and acidified with sulfuric acid in the reactor vessel.
