Chapter 5: Mineral and Energy Resources

Introduction

  • India has a rich variety of mineral resources due to its varied geological structure.
  • Valuable minerals are primarily from the pre-palaezoic age, associated with metamorphic and igneous rocks of peninsular India.
  • The alluvial plains of north India lack economically useful minerals.
  • Mineral resources are essential for industrial development.

Types of Mineral Resources

  • Classification Based on Chemical and Physical Properties:
    • Metallic Minerals
      • Ferrous (e.g., Iron, Manganese)
      • Non-Ferrous (e.g., Copper, Bauxite)
    • Non-Metallic Minerals
      • Fuel Minerals (e.g., Coal, Petroleum, Natural Gas)
      • Other Non-Metallics (e.g., Mica, Limestone, Graphite)

Conservation of Mineral Resources

  • Sustainable development requires balancing economic growth with environmental protection.
  • Traditional resource use generates waste and environmental issues.
  • Urgent need to conserve resources for future generations.
  • Development of alternative energy sources (solar, wind, geothermal) is crucial.
  • Recycling of metals, especially scarce ones like copper, lead, and zinc, is important.
  • Reducing export of strategic minerals can prolong existing reserves.

Bio-Energy

  • Derived from biological products, including agricultural residues and waste.
  • Can be converted into electrical energy, heat energy, or cooking gas.
  • Projects like Okhla in Delhi convert municipal waste into energy, improving rural economic life and reducing pollution.

Non-Conventional Energy Sources

  • Wind Energy: Utilizes permanent and seasonal winds; favorable conditions exist in Rajasthan, Gujarat, Maharashtra, and Karnataka.
  • Tidal and Wave Energy: Potential along the west coast of India; not yet fully utilized.
  • Geothermal Energy: Tapped from magma heat; a geothermal plant exists at Manikaran in Himachal Pradesh.

Conclusion

  • India's mineral and energy resources are vital for its development, and sustainable practices are essential for future generations.
