The separation of the Chota Nagpur plateau from Bihar to form the state of Jharkhand in 2000 resulted in the virtual depletion of Bihar’s mineral wealth.12

Because the Chota Nagpur region serves as India's primary mineral belt—containing vast reserves of coal, iron ore, bauxite, copper, and mica—its loss significantly diminished Bihar's industrial resource base. Additionally, the partition caused Bihar to lose several hydroelectric power and thermal power stations, further straining the state's energy infrastructure.31

Following this transition, Bihar’s remaining mineral production is limited to a few specific pockets:1
* Bauxite: Found in Munger.1
* Dolomite and construction materials: Located in the Rohtas district.1
* Mica and salt: Found in Gaya, Nawada, and Munger, with additional salt production in Muzaffarpur.1
