Introduction to Mineral and Energy Resources
- Definition: Minerals are naturally occurring, inorganic substances with a definite chemical composition and physical properties.
- Minerals are classified as metallic, non-metallic, and energy minerals based on their composition and use.
- India is rich in mineral resources, with deposits of coal, iron ore, bauxite, and manganese being among the largest in the world.
- The formation of minerals depends on geological processes such as crystallization, sedimentation, and metamorphism.
- Mineral resources are unevenly distributed across India, with regions like Jharkhand, Odisha, Chhattisgarh, and Rajasthan having significant reserves.
- Mining and extraction of minerals impact the environment, leading to deforestation, pollution, and land degradation.
- The Indian mining sector is regulated by laws like the Mines and Minerals (Development and Regulation) Act, 1957.
- Minerals are essential for industrial development, infrastructure, and economic growth.
- India is focusing on sustainable mining practices to balance economic development with environmental protection.
- The government has launched initiatives like Atmanirbhar Bharat and the National Mineral Policy (2019) to boost domestic mineral production.
