Muscovite Mineral | Uses and Properties

Muscovite can form during the regional metamorphism of argillaceous rocks. The heat and pressure of metamorphism transforms clay minerals into tiny grains of mica which enlarge as metamorphism progresses. Muscovite can occur as isolated grains in schist and gneiss, or it can be abundant enough that the rocks are called "mica schist" or "micaceous gneiss."

Muscovite Mineral | Physical

Muscovite is the most common mineral of the mica own family. It is an essential rock-forming mineral present in igneous, metamorphic, and sedimentary rocks. Like other micas it with no trouble cleaves into skinny transparent sheets. Muscovite sheets have a pearly to vitreous luster on their floor. If they''re held up to the light, they''re ...

This is achieved by propelling the particles at high speed into a confined enclosure which results in interparticle comminution. Superheated steam or compressed air can be used as the vehicle to effect micronization, particle size being controlled by residence time in the mill and removal of oversize particles by air classification.

Muscovite Mineral | Physical

 · Muscovite is a widespread and very common rockforming mineral. Characteristic of deep-seated siliceous igneous rocks as granite and syenite. Especially characteristic of pegmatite dikes, and found lining cavities in granites, where it has evidently been formed by the action of mineralizing vapors during the last stages of the formation of the rock.
