Grinding of rock phosphate and its impact on optimisation ...

In production of phosphoric acid, primary purpose of rock phosphate comminution is to expose or create sufficient porous surface area to allow complete dissolution of the rock in relatively short duration at the conditions of acid strengths and temperature prevailing in reactor or attack tanks. Secondary purpose is to reduce power input to agitators in the attack circuits.
