Phosphoric Acid

Ground up rock slurry is mixed with sulfuric acid and recycled phosphoric acid in either a series of "attack tanks" or in larger volume tanks with draft tube mixers. A mixer must not only suspend phosphoric rock and blend acids; it must also create sufficient velocity to discourage gypsum, a by-product, from building up on the tank walls.
