The North-Eastern Peninsular Belt
The North-Eastern Peninsular Belt is known as the richest mineral belt in India. This belt is located in the states of Odisha, Jharkhand, and West Bengal in eastern India. It is a significant mining region and is known for its abundant mineral resources.

Minerals found in the North-Eastern Peninsular Belt:
1. Coal: The belt is rich in coal deposits, with major coalfields such as Jharia, Raniganj, and Bokaro located in this region. These coalfields have been the backbone of India's energy sector and have contributed significantly to the country's industrial development.

2. Iron ore: The North-Eastern Peninsular Belt is also rich in iron ore deposits. Major iron ore mines in this region include those in Keonjhar, Mayurbhanj, and Sundergarh districts of Odisha. These mines contribute to a significant portion of India's iron ore production.

3. Manganese: The belt is also known for its manganese deposits. The Keonjhar district in Odisha is particularly rich in manganese ore. Manganese is an essential element used in the production of steel and other alloys.

4. Bauxite: Bauxite, which is the primary ore used in the production of aluminum, is also found in abundance in the North-Eastern Peninsular Belt. The Panchpatmali mines in Odisha are one of the largest bauxite mines in the world.

5. Copper: The belt also has significant copper deposits. The Singhbhum Copper Belt, located in Jharkhand and adjacent areas of Odisha, is known for its copper reserves. Copper is an important metal used in various industries, including electrical and electronics.

Importance of the North-Eastern Peninsular Belt:
The North-Eastern Peninsular Belt plays a crucial role in India's mining and industrial sectors. The rich mineral resources in this belt have contributed to the country's economic growth and development. The coal mines in this region have provided fuel for power generation and industries, while the iron ore and manganese mines have supported the steel and alloy industries. Additionally, the bauxite and copper deposits have contributed to the production of aluminum and copper products.

The mineral-rich belt has also created employment opportunities for the local population and has attracted investments in mining and related industries.
