Detailed Summary of Mica

Mica is a non-metallic mineral characterized by its unique property of cleavage into thin sheets. These sheets can be layered, making mica invaluable in various applications. It possesses excellent dielectric strength and insulating properties, which are vital for the electrical and electronic industries. The main deposits in India are located in the Koderma-Gaya-Hazaribagh belt of Jharkhand and regions of Rajasthan and Andhra Pradesh.

Mica is used in several products, including electrical insulators, paints, cosmetics, and as a filler in various materials. Due to its excellent insulating properties and resistance to high temperatures, it is crucial in enhancing the performance of electrical equipment. Therefore, the mining and sustainability of mica extraction present significant challenges and environmental concerns in India. Proper care must be taken to mitigate the adverse impacts of mica mining while also fostering sustainable practices.
