Mica is a mineral that is used in a variety of products, including electrical insulation, cosmetics, and roofing materials. It is a soft, flaky mineral that is found in schist and gneiss rocks. Mica is mined in open-pit and underground mines. The ore is crushed and then ground into a powder. The powder is then separated into different grades based on its quality. The highest grade mica is used in electrical insulation. The lower grades of mica are used in cosmetics, roofing materials, and other products.
Rajasthan is the largest producer of mica in India because it has the largest deposits of the mineral. The state’s mica mines are located in the districts of Bikaner, Jaisalmer, and Jodhpur. The mica industry in Rajasthan is an important source of employment for the state’s population.
