grinding of muscovite


Posted on November 20, 2018



Method for grinding and delaminating muscovite - ScienceDirectA method of dry grinding muscovite based on the use of knife-mills is reported. It was possible to produce mica with a particle size below 100 and 45 μm. After grinding, the samples were submitted to sonication treatment, which promoted delamination of the material. The particle size distribution shows that sonicated mica.grinding of muscovite,grinding of muscovite,Variation of the surface energy characteristics of mica (muscovite .Inverse gas chromatography (IGC), at zero surface coverage, has been used to follow the variation of the surface free energy characteristics of muscovite samples after grinding either in water or in organic media. For initial mica, the value of γSD measured through IGC, is in agreement with the values given by other methods.

Mica

Muscovite has the greatest commercial value and is the mica that is ground and pulverized into pigment grades. Muscovite crystals develop in booklike form with a well-developed basal cleavage that allows splitting the large books into extremely thin sheets or grinding the flakes into thin leaves to produce dry ground mica.
