Which Indian state is the leading producer of mica, holding major reserves of crude mica in regions like Koderma and Hazaribagh?

💡 Solution & Explanation

Jharkhand holds major reserves of crude mica, particularly across the Hazaribagh and Koderma districts, making it a historically prominent mica producer in India. Other mineral-rich states like Rajasthan and Odisha excel in different resources such as limestone and iron ore rather than being the primary hub for mica.
