Conservation Of Minerals
1. Dependence on Minerals:
- Industries and agriculture are heavily reliant on mineral deposits.
- Workable mineral deposits form only 1% of the Earth’s crust.
- Mineral resources are finite and non-renewable.
- Geological processes of mineral formation are slow, making replenishment rates negligible.
- Continuous extraction leads to higher costs and declining quality of ores.
2. Sustainable Use of Minerals:
- Planned and sustainable resource usage is essential.
- Technologies for using low-grade ores at reduced costs need to be developed.
- Recycling metals and using substitutes conserve mineral resources.
3. Energy Resources:
- Energy is essential for cooking, lighting, heating, transportation, and industrial machinery.
- Energy sources are classified as:
a. Conventional sources: Coal, petroleum, natural gas, firewood, cattle dung cake, hydel, and thermal electricity.
b. Non-conventional sources: Solar, wind, tidal, geothermal, biogas, atomic energy.
4. Coal:
- India’s most abundant fossil fuel, meeting substantial energy needs.
- Forms of coal:
a. Peat: Low carbon, high moisture, low heating capacity.
b. Lignite: Low-grade brown coal; reserves in Neyveli, Tamil Nadu.
c. Bituminous coal: Most used commercially; high-grade variant used in iron smelting.
d. Anthracite: Highest quality, hard coal. - Coal deposits:
a. Gondwana coal: Found in Damodar, Godavari, Mahanadi, Son, and Wardha valleys.
b. Tertiary coal: Found in Meghalaya, Assam, Arunachal Pradesh, Nagaland.
5. Petroleum:
- The second major energy source in India.
- Provides fuel, lubricants, and raw materials for industries like textiles, fertilizers, and chemicals.
- Petroleum occurrences:
a. Found in anticlines, fault traps, and porous rocks (limestone/sandstone).
b. Major production areas: Mumbai High, Gujarat, Assam.
6. Natural Gas:
- Found with petroleum deposits; used in various industries and as domestic fuel.
- Emerging as a preferred fuel for transport (CNG) and homes (PNG).

- Infrastructure: The HVJ pipeline links western and northern India.
7. Electricity:
- Index of development due to wide applications.
- Generated in two ways:
a. Hydro electricity: Renewable, generated by flowing water.
b. Thermal electricity: Generated using fossil fuels like coal, petroleum, and natural gas.
8. Non-Conventional Sources of Energy:
- Importance due to fossil fuel shortages and environmental concerns.
- Examples: Solar, wind, tidal, biomass, geothermal energy.
- India’s largest renewable energy programmes include solar and wind power.
9. Nuclear Energy:
- Generated using uranium and thorium.
- Major reserves: Jharkhand, Rajasthan (Aravalli), Monazite sands in Kerala.
- Six nuclear power stations in India.
10. Solar Energy:

- Applications: Rural and remote areas to reduce dependence on firewood and dung cakes.
11. Wind Energy:
- High potential in India.
- Major wind farm clusters: Tamil Nadu, Gujarat, Karnataka, Maharashtra, Kerala, Lakshadweep.
12. Biogas:
- Produced from organic waste; it is efficient compared to kerosene and dung cakes.
- Gobar gas plants benefit farmers by providing energy and manure.
13. Tidal Energy:
- Generated using oceanic tides with floodgate dams.
- Potential sites: Gulf of Khambhat, Gulf of Kutch, Gangetic delta in Sunderbans.
14. Geothermal Energy:
- Utilizes Earth’s internal heat.
- High geothermal gradient areas: Parvati Valley (Himachal Pradesh), Puga Valley (Ladakh).
