Study Notes
Major Minerals
- Major minerals include copper and zinc, essential for various industries.
- Assam and Mumbai High are significant for mineral deposits, with oil being a primary focus.
- Rajasthan is rich in building stones, including sandstone, granite, and marble, alongside gypsum and fuller’s earth.
Ferrous Minerals
- India possesses the largest iron ore reserves in Asia, primarily haematite and magnetite types.
- Major iron ore production is concentrated in Odisha, Karnataka, and Chhattisgarh, among other states.
- Manganese is crucial for ferro alloys and is mainly found in the Dharwar system, with Odisha as the leading producer.
Non-Ferrous Minerals
- Bauxite is vital for aluminum production, with significant deposits in Odisha and Jharkhand.
- Copper, needed for electrical applications, is primarily sourced from Jharkhand, Madhya Pradesh, and Rajasthan.
Non-Metallic Minerals
- Mica is essential for electrical industries and is produced mainly in Jharkhand and Andhra Pradesh.
- Other non-metallic minerals include limestone, dolomite, and phosphate.
Energy Resources
- Coal is primarily used for thermal power generation; bituminous coal dominates Indian reserves.
- Petroleum, referred to as "liquid gold," is extracted primarily from Assam, with other regions becoming prominent after 1956.
- Natural gas, found alongside petroleum, serves as a significant domestic and industrial fuel source.
Non-Conventional Energy
- Renewable energy sources include solar, wind, hydro, geothermal, and biomass, providing environmentally friendly options.
- India has untapped potential for tidal energy along its coast, with limited development so far.
- Nuclear energy is generated from uranium and thorium, managed by the Atomic Energy Commission.
Bio Energy
- Bio energy is derived from agricultural residues and municipal waste, contributing to alternative energy solutions.
- Emphasizes the importance of developing non-conventional resources to reduce reliance on exhaustible resources.
Conservation of Mineral Resources
- Importance of sustainable practices in mineral extraction to prevent over-exploitation.
- Utilize scrap metals to promote recycling and efficiency in mining processes.
- Strategic minerals should be processed near mining sites to reduce transport costs and extend reserve usage.
Map Work
- Key areas include Balaghat, Mayurbhanj, Bailadila, Ratnagiri for manganese mines.
- Notable iron-ore mines are located in regions like Ballari and Shivamogga.
- Bauxite, copper, and coal mines are concentrated in states like Bihar, Katni, and West Bengal, respectively.
