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.

What is Mica? Mica refers to a group of 37 silicate mineral compounds that are naturally sourced. They're all physically and chemically similar but come in different colors. Examples are brown phlogopite, clear muscovite, and purple lepidolite. Besides silicate, these minerals also contain aluminum, iron, magnesium, and potassium.

Grinding Dry Grinding Wet Grinding Production Uses In recent years, more than 99 percent of the domestic mica produced has been scrap and flake mica (mica which does not meet specifications for sheet mica and which is used for producing fine-ground mica). There has been a continued increase in mica production for several years.

Mica, which is essentially a compound of silicate minerals, is comprised of closely related materials that have perfect basal cleavage. They belong to the category of principal rock-forming minerals and are found in various categories like sedimentary, igneous, and metamorphic.

This is why special mills (the chaser mill for wet-ground or the fluid-energy mill for dry ground) and long periods of grinding are necessary for comminution of micas and other layered minerals. This results in high-cost final products [5]. Recent studies have described the use of a knife-mill for particle size reduction of micas, however.
