The extraction of mica primarily involves mining, which can be categorized into two methods natural and synthetic. Natural mica is predominantly mined in countries like India, Madagascar, and China. Open-pit mining is the most common method, where the topsoil is removed to expose the mica-bearing rock. Miners then extract the mica flakes, which vary in size and quality. This method, while effective, raises serious environmental concerns. Deforestation, loss of biodiversity, and soil erosion are grave consequences. Moreover, the labor practices associated with mica mining can be deeply troubling, particularly in regions where child labor and unsafe working conditions are prevalent.

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.
