In conclusion, mica is a unique and versatile mineral that plays a crucial role as a component of some metamorphic rocks while simultaneously serving a wide array of industrial applications. Its physical properties make it invaluable in electronics, cosmetics, and various coatings, while its geological significance allows for a deeper understanding of metamorphic processes. As the world moves toward sustainable practices, the conversation surrounding mica extraction will continue to evolve, emphasizing the balance between industrial advancements and ethical considerations.

Later, with the development of science and technology, people gradually realized that mica minerals have high insulation, high temperature resistance, strong acid and alkali resistance, and mica also began to enter building materials, fire, plastics, paper, rubber, pearlite pigments and other industries. These are mainly Muscovite and phlogopite.
