minerals — BSSC Geography

• Odisha produces ~50% of India’s bauxite and has the highest reserves.

• Major districts in Odisha include Koraput and Kalahandi.

• Bauxite is the primary ore for Aluminium.

• Jharkhand and Gujarat are leading producers but do not account for >50%.

• Trick: 'Odisha is the Boss of Bauxite' (Boss -> Bauxite).

• Panchpatmali deposits in Koraput are the most important bauxite deposits in Odisha.

• Tummalapalle in Andhra Pradesh is one of the world’s largest uranium reserves.

• Andhra Pradesh is also the largest producer of Uranium in India.

• Uranium Corporation of India Ltd manages uranium mining in India.

• Jharkhand has Jaduguda mines, but Tummalapalle is in AP.

• Trick: 'Tumma (Andhra) has Tons of Uranium'.

• Kazakhstan is the largest Uranium producing country in the world.

• Narora is in Uttar Pradesh (a-4).

• Kakrapar is in Gujarat (b-2).

• Kudankulam is in Tamil Nadu (c-3) and Kaiga is in Karnataka (d-1).

• Incorrect options misalign these well-established atomic power stations.

• Trick: 'Ka-Ka' -> Kakrapar-Gujarat, 'Kuda-Tamil' -> Kudankulam-Tamil Nadu.

• Tarapur (Maharashtra) was India’s first nuclear power station.

• GSI conducts mineral exploration and provides geoscience data.

• It operates under the Ministry of Mines.

• IBM regulates mining, conducts inspections, and maintains mining data.

• MECL is a PSU engaged in actual exploration and production, not just geoscience data.

• Trick: 'Survey' means gathering data (GSI), 'Bureau' means regulation (IBM).

• Non-ferrous metals are also developed under the Ministry of Mines.

• Anthracite has the highest carbon (80-95%).

• Bituminous has 60-80% carbon.

• Lignite contains 40-55% carbon, and Peat has less than 40%.

• Any other sequence violates the geological maturity of coal.

• Trick: 'A B L P' (Alphabetical order perfectly matches highest to lowest carbon).

• Anthracite is the hardest coal and burns long with less ash.

• The 2021 Amendment allowed commercial auctions and removed end-use restrictions.

• It actually opened private exploration, not restricted it.

• The MMDR Act of 1957 governs mining and exploration.

• Option 2 is factually incorrect as the act liberalized the sector.

• Trick: 'Amendment 2021 = Open Market' (Commercial, Private, No end-use limit).

• Coal, petroleum, and atomic minerals are excluded from this specific regulation scope.

• Hornblende is an inosilicate amphibole mineral.

• It is used as an aggregate for road bases and railroad ballast to provide stability.

• Railroad ballast provides drainage and support under the tracks.

• Shale and Olivine are different silicate/sedimentary rocks not primarily used for this.

• Trick: 'Horn-blende blends the roads and rails together.'

• Geyserite is a form of opaline silica found around hot springs.

• Damodar Valley is called the 'Ruhr of India' due to similarities with Germany’s coal-rich Ruhr region.

• 97% of India’s total coal reserves lie in river valleys (Damodar, Sone, Mahanadi), mostly bituminous, not lignite.

• Lignite deposits mainly occur in Tamil Nadu, Gujarat, and J&K.

• R is false because the 97% figure applies to total Gondwana coal, not lignite specifically.

• Trick: Ruhr = Damodar = Bituminous coal.

• Indian coal has high ash content (40-45%).

• Bhadla Solar Park in Rajasthan is the world’s largest solar park.

• It spans across 14,000 acres in the Jodhpur district.

• Solar energy is a rapidly growing renewable/non-conventional energy source.

• Pavagada is in Karnataka, and Dholera/Harshad are in Gujarat, but they are smaller than Bhadla.

• Trick: 'Bhadla is Bada (Big)' -> Largest Solar Park.

• India aims for 280 GW of solar power by 2030.

• Magnetite has the highest iron content (~72%).

• Siderite is the carbonate of iron, not Limonite.

• Limonite is brown in colour (bog iron), whereas Siderite is interbedded with carbonaceous rocks.

• Statements 2 and 3 swap the properties of Limonite and Siderite.

• Trick: 'Siderite = Carbonate' (C and S sound related). Limonite = Lemon = Yellow/Brown.

• Haematite is the most used iron ore in industries in terms of quantity.
