The mica belt in the northern part of Chota Nagpur Plateau is about 160 km long with an average width of about 25 km. It covers in Koderma and Giridih districts of Jharkhand and adjacent areas in Bihar. Mica deposits were discovered in the area in the 1890s, and mica mining developed in a big way. It was exported in large quantities primarily to the Soviet Union. In the 1990s, when the Soviet Union was divided, the countries in the area stopped buying mica from India. It was a major set back for the mica industry. Moreover, the entire mica belt is located in the reserved forests. The forest conservation act was implemented in 1980. When the business was booming almost every household in the mica belt was involved in mica mining. Alternative employment opportunities are rare and so even after formal closing down of the mica mines, almost the entire community in the mica mining belt is involved in illegal mining activities. Mica continues to be in demand locally. It is mainly used in the pigmentation industry for automotive paints and cosmetics. Some other industries also use it. The entire family, including children, are involved in the illegal activity.[18]
