Minerals & Energy Resources of India

Study Notes · General Studies

Complete guide to India's mineral and energy resources — coal, iron ore, petroleum, renewable energy, and mining policy. Essential for UPSC Geography.

India is endowed with significant mineral wealth spread across its geological formations — from the ancient Precambrian rocks of the Peninsular Plateau to the sedimentary basins holding fossil fuels. The country ranks among the top global producers of coal, iron ore, bauxite, and mica. For UPSC, mineral distribution, energy policy, and the transition toward renewables are tested across Geography, Economy, and Environment papers.

Classification of Minerals

Minerals are classified based on their composition, use, and the method of extraction.

Metallic — Non-ferrousCopper, bauxite, lead, zinc, gold, tinDon't contain iron; used in electrical, aerospace
Non-metallicMica, limestone, gypsum, dolomite, saltIndustrial and construction applications
Energy MineralsCoal, petroleum, natural gas, uranium, thoriumFuel and power generation

By Mode of Occurrence

Metallic Minerals of India

Iron Ore

India holds about 8% of the world's iron ore reserves, estimated at over 33 billion tonnes. The country is the fourth-largest producer globally.

Major producing regions:

India primarily has haematite (high-grade, 60-70% iron content) found in Odisha, Jharkhand, and Chhattisgarh, and magnetite found in Karnataka and Goa.

Manganese

India is the fifth-largest manganese producer globally. Manganese is essential for steel manufacturing — about 10 kg is needed per tonne of steel.

Major producers: Odisha (largest), Maharashtra (Nagpur, Bhandara), Madhya Pradesh (Balaghat), Karnataka, and Andhra Pradesh.

Bauxite

Bauxite is the primary ore of aluminium. India has about 3.5 billion tonnes of reserves, ranking fifth globally.

Major deposits: Odisha (Koraput — largest), Jharkhand (Lohardaga — high quality), Gujarat (Kutch, Jamnagar), Maharashtra, Chhattisgarh, and Tamil Nadu.

Copper

India's copper reserves are modest. Major deposits are found in:

Gold

India’s gold production is minimal compared to consumption. The Kolar Gold Fields (Karnataka) — once among the world’s deepest mines — ceased operations in 2001. Hutti Gold Mines in Karnataka remain active. Rajasthan’s Banswara district has significant untapped deposits.

Non-Metallic Minerals

Mica

India was historically the world's largest mica producer. Mica is used in electrical insulation, cosmetics, and heat-resistant applications.

Major deposits:

Limestone

India is the fifth-largest limestone producer. It's essential for cement manufacturing and the steel industry (as flux).

Major producers: Rajasthan (largest), Madhya Pradesh, Andhra Pradesh, Karnataka, and Gujarat. The Vindhyan system contains extensive limestone deposits.

Coal: India's Primary Energy Source

Coal accounts for about 55% of India's primary energy supply and over 70% of electricity generation. India has the fifth-largest coal reserves globally — approximately 361 billion tonnes (as of 2023 estimates).

Types of Coal in India

TypeCarbon ContentLocationUse
Anthracite80-95%Jammu & Kashmir (small deposits)High-grade fuel; very rare in India
Bituminous60-80%Jharkhand, West Bengal, Odisha, ChhattisgarhPower generation, steel making
Lignite40-55%Tamil Nadu (Neyveli), Rajasthan, GujaratPower generation; lower calorific value
Peat<40%Limited depositsRarely mined commercially

Major Coalfields

Gondwana Coal (98% of reserves, 99% of production):

Tertiary Coal (2% of reserves):

Coal Sector Reforms

The nationalisation of coal mines (1973) created Coal India Limited (CIL), the world's largest coal producer. Key recent reforms include:

Petroleum and Natural Gas

India is the third-largest energy consumer globally but produces only about 15% of its crude oil needs domestically. The country imports approximately 85% of its crude oil requirement.

Major Oil-Producing Regions

RegionKey FieldsShare of Production
Western Offshore (Mumbai High)Bombay High, Bassein, Heera-Panna~50% of domestic production
AssamDigboi (oldest), Naharkatiya, Moran~10%
GujaratAnkleshwar, Kalol, Ahmedabad~10%
RajasthanBarmer-Sanchore Basin (Mangala, Bhagyam)~20%
Eastern Offshore (KG Basin)KG-D6 (Reliance), ONGC fields~10%

Digboi in Assam is Asia's oldest operating oilfield, with production beginning in 1889. Bombay High (discovered 1974) transformed India's oil production landscape.

Natural Gas

India's major gas-producing basins include the Krishna-Godavari Basin (KG Basin), Mumbai Offshore, Assam, and Rajasthan. The KG-D6 block, operated by Reliance Industries, has been a significant albeit controversial gas source.

Key policy developments:

Nuclear Energy

India has a three-stage nuclear power programme designed by Homi Bhabha to exploit the country's thorium reserves (world's largest) given limited uranium deposits.

Three Stages

StageTechnologyFuelStatus
Stage IPressurised Heavy Water Reactors (PHWR)Natural uraniumOperational (22 reactors)
Stage IIFast Breeder Reactors (FBR)Plutonium from Stage IPrototype FBR at Kalpakkam (nearing completion)
Stage IIIAdvanced Heavy Water ReactorsThorium-U233Research phase

Key nuclear plants: Tarapur (Maharashtra — first), Rawatbhata (Rajasthan), Kalpakkam (Tamil Nadu), Narora (UP), Kakrapar (Gujarat), Kudankulam (Tamil Nadu — VVER with Russian collaboration).

India's nuclear capacity stands at approximately 7,480 MW from 22 operational reactors, with a target of 22,480 MW by 2031.

Renewable Energy Resources

India has set ambitious renewable energy targets — 500 GW of non-fossil fuel capacity by 2030 and net-zero carbon emissions by 2070.

Mining Governance

The Mines and Minerals (Development and Regulation) Act, 1957 (MMDR Act) is the primary legislation governing mining. Recent amendments (2015, 2020, 2021, 2023) have introduced auction-based allocation, district mineral foundations, and exploration licences.

Frequently Asked Questions

Which state is the largest producer of iron ore in India?

Odisha is India's largest iron ore-producing state, contributing about 50% of national output. The Keonjhar, Sundargarh, and Mayurbhanj districts contain extensive haematite deposits. Chhattisgarh and Jharkhand are the next largest producers, with the Singhbhum-Keonjhar belt forming the most important iron ore region.

What percentage of crude oil does India import?

India imports approximately 85% of its crude oil requirement, making it one of the most import-dependent major economies. Domestic production from fields like Bombay High, Rajasthan's Barmer basin, and Assam meets only about 15% of demand. This dependency makes India vulnerable to global price volatility.

What is India's three-stage nuclear programme?

Designed by Homi Bhabha, the programme uses natural uranium in Pressurised Heavy Water Reactors (Stage I), plutonium bred from Stage I in Fast Breeder Reactors (Stage II), and ultimately thorium-based reactors (Stage III). The goal is to exploit India's vast thorium reserves — the world's largest — for long-term energy security.

Which coalfield produces the best coking coal in India?

Jharia coalfield in Jharkhand produces India's best metallurgical (coking) coal, essential for steel manufacturing. However, Jharia has faced severe problems including underground fires burning for over a century, land subsidence, and environmental degradation. Most of India's coal is non-coking thermal coal used for power generation.

What is India's renewable energy target?

India aims for 500 GW of installed non-fossil fuel electricity capacity by 2030, as announced at COP26 in Glasgow. The country has also committed to net-zero emissions by 2070. Solar and wind energy form the bulk of this target, supported by policies like the National Green Hydrogen Mission and the International Solar Alliance.
