The 1st question to ask is the phase in which the milling must happen. If it is in wet phase, the choice will be mainly towards an agitated ball mill or, if the milling is easy and the size reduction expected not too important, a colloid mill.

Phosphate minerals, such as apatite, are one of the main sources for the production of phosphoric acid. The wet process and clean process are the main hydrometallurgical methods for phosphoric acid production. Wet processing, using the digestion of phosphate rocks by sulphuric acid, is the most common process used to produce phosphoric acid.
