The main component of rock phosphate is calcium phosphate (tricalcium phosphate, dicalcium phosphate) which is insoluble in water and thus unavailable to plants. During rock phosphate processing, phosphorus is extracted by dissolving the rock phosphate in low-pH solutions (sulfuric acid, nitric acid, or hydrochloric acid).
Wet Process Phosphoric Acid Production | Vaisala
The wet process consists of reaction, filtration and concentration steps. The phosphate rock is ground and acidified with sulfuric acid in the reactor vessel. In the reaction, the tricalcium phosphate in the phosphate rock is converted to phosphoric acid and to the insoluble salt calcium sulfate (CaSO 4), also known as gypsum.
