Mined phosphate rock is sold to phosphate processing plants that digest the rock using sulfuric acid to make phosphoric acid. The vast majority of phosphoric acid is used in the production of fertilizers to grow the food the world needs; additionally, phosphoric acid is also used as an additive in livestock feed and even in food products.
