Process Technology of Phosphoric Acid. There are two main commercial processes to produce phosphoric acid: the wet process and the dry [] (electrical furnace) process.Although, the acid produced (technical grade) with the dry process is pure, its production cost is much higher than that of the wet process phosphoric acid (WPPA or fertilizer grade acid).

This example shows that the rock grinding rate (and ball erosion rate) is critical to the proper operation of the invented process. A higher rock grinding rate exposes more surface area of the phosphate rock to the acidic slurry and produces more high-surface area particulate iron for reaction with the pond water.
