The mica variety that does not contain iron is colorless in flakes, and the higher the iron content, the darker the color, and the more polychromatic and absorbable it is. According to the different chemical composition and optical characteristics, mica group minerals can be divided into Muscovite subgroup, biotite-phlogopite subgroup and lemica subgroup. The common mica are biotite, phlogopite, Muscovite and so on.

Mica is a group of silicate minerals that can be found in crystalline forms. When mined, it is ground into a fine powder that can be used in various applications, with the beauty industry being one of the largest consumers. Mica powder typically comes in various colors and finishes, ranging from matte to highly reflective, making it versatile for different cosmetic formulations.

3. Flotation and Screening The crushed material is then subjected to a flotation process, where chemicals are added to separate mica from impurities. Screening follows, enabling the further refinement of mica by sorting it into different grades based on size and quality.
