Step 1: Wetting. The first step to wet grinding is eliminating air from the surface of the raw feed, so that each individual particle is fully in contact with the liquid slurry. Ensuring complete contact is vital for effective milling. This requires a liquid with lower surface tension than the free surface energy of the solid.

Mica is one of the most difficult minerals to grind. Some of the same properties that make mica useful make it difficult to grind. Even thin flakes are tough and elastic and resist abrasion and reduction in size by conventional types of grinding equipment. Two processes, dry grinding and wet grinding, are employed to produce ground mica.
