Systematic review of feldspar beneficiation and its comprehensive

It is known that grinding consumes more energy than crushing. Therefore, it is better to crush more and grind less. Additionally, wetting grinding is better than dry grinding for it could get rid of "overgrinding". De-sliming operations could help reduce the impurities, decrease the feed of grinding and therefore save the energy. 3.2.

Rare and Hard to Find Art Supplies | Mica (Wet Ground)

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.
