Mechanical activation of the phosphate rock

Phosphoric acid is produced by either a dry or a wet process In the dry process, phosphate rock is treated in an electric furnace to produce a very pure and more expensive phosphoric acid (frequently called white or furnace acid) In the wet process, the phosphate rock was treated with acid producing phosphoric acid (also called green or...
