Study Notes

Minerals & Energy Resources

  • Minerals are naturally occurring, homogenous substances with a definable internal structure.

  • Minerals are essential in many applications, including railway lines, road surfacing (tarmac), machinery, automobiles, food, and everyday life.

  • Minerals are used in various aspects of livelihood, decoration, and festive celebrations. Life processes depend on minerals.

  • Minerals contribute 0.3% of direct nutrient intake, with the remaining 99.7% acting as complements.

  • Minerals are crucial components of toothpaste, including abrasives like silica, limestone, and aluminum oxide, and phosphates for cleaning. Fluoride from fluorite reduces cavities. Other components of toothpaste include titanium oxides (from minerals like rutile and ilmenite) and mica for sparkle.

Rocks

  • Rocks are combinations of homogenous substances (minerals).

  • Mineral formation depends on physical and chemical conditions.

  • Minerals are found in ores, accumulations of minerals mixed with other minerals.

  • The mineral content of an ore must be high for economical extraction.

Mode of Occurrence of Minerals

  • Minerals are found in various forms: veins & lodes (e.g., tin, lead, copper), beds & layers (e.g., coal, gypsum), residual masses of weathered material (e.g., bauxite), and alluvial deposits (e.g., gold, silver).

Mineral Distribution in India

  • Mineral distribution in India varies due to geological structure, processes, and time.
  • Key regions and their mineral deposits are detailed in the provided notes.

When Does a Mineral Deposit Become a Mine?

  • Mineral deposits become mines based on factors including mineral concentration, extraction ease, and proximity to markets. These all affect economic viability and the reserve's value.

Classification of Minerals

Limestone

  • Limestone, a sedimentary rock composed of calcium carbonate (CaCO3), is used extensively in cement production and iron smelting.
  • Key limestone regions include Rajasthan and Madhya Pradesh.

Hazards of Mining

  • Mining poses significant hazards, including respiratory illnesses for miners, risk of collapse, accidents, contamination from waste, and land degradation.

Conservation of Minerals and Energy

  • Conservation of minerals and energy resources is necessary as they are finite and non-renewable.
  • Methods to conserve include improved technology for extracting lower-quality ores, recycling, utilizing non-conventional energy sources, judicious resource use, and public transport incentives.

Energy Resources

  • Energy resources include conventional (coal, petroleum, natural gas, electricity) and non-conventional (solar, wind, biogas, tidal, geothermal, nuclear) options.
  • Coal types include peat, lignite, bituminous, and anthracite, categorized by their degree of compression and formation depth.
  • Coal is widely used for electricity generation and industry.
  • Petroleum is critical for the transportation and industrial sectors.
  • Natural gas is essential for domestic and industrial energy needs.
  • Major petroleum regions in India include Mumbai High, Gujarat, Assam (Digboi), Naharkatiya, and Moran-Mughilan.
  • Natural gas regions are Mumbai High, Cambay, and Krishna-Godavari basins.

Electricity Generation

  • Electricity generation methods include hydro power (using running water), thermal power (using fossil fuels), and nuclear power.
  • Key hydroelectric project sites are detailed in provided notes.

Non-Conventional Energy Sources

  • Non-conventional energy sources include nuclear, solar, wind, biogas, and tidal energy.
  • Nuclear energy involves altering atomic structure to produce heat for generating electricity and is obtained from Uranium, Thorium, and Monazite sands in specific Indian regions. Solar power uses photovoltaic technology to convert sunlight to electricity.
  • Wind power utilizes wind turbines to generate electricity. Biogas uses the decomposition of organic matter to produce combustible gases which are used in power and cooking. Tidal energy converts the rise and fall of tides into usable energy.
