India has a near monopoly in the production of mica, producing about 60 per cent of world's total production. About 95% of India's mica is distributed in just three states of Jharkhand, Andhra Pradesh and Rajasthan. Jharkhand has richest mica belt and accounts for 60% of India's production in terms of value. Here, mica is found in a belt extending for about 150 km in length and 32 km in width from Gaya district of Bihar to Hazaribagh and Kodarma districts of Jharkhand. Kodarma is a well-known place for mica production in Jharkhand which produces more than 50% of the total mica production in India. India is not only the largest producer but also the largest exporter of mica in the world. In spite of the threat from synthetic mica, certain grades of Indian mica will remain vital to the world's electrical industries. Most of the exports are routed through the ports of Kolkata and Vishakhapatnam.
