Detailed Solution

Koderma, in Jharkhand, is the leading producer of mica.
Mica is a non-metallic mineral made up of a series of plates or leaves and can be split fluently into thin sheets, which can be so thin that a thousand such sheets can be layered into a mica sheet a few centimetres high. It occurs in various colours like black, green, red, yellow, or brown. It is one of the most indispensable minerals used in electric and electronic industries due to its remarkable dielectric strength, insulating properties, low power loss factor, and resistance to high voltage. Mica deposits are found in the Nellore belt of Andhra Pradesh, the northern edge of Chota Nagpur, and Ajmer.
