Mineral and Energy Resources of India

Overview

India is richly endowed with metallic and non-metallic minerals but faces energy security challenges due to:

• Heavy dependence on imported crude oil (~85% of consumption).
• Underutilised domestic coal reserves (world's 4th largest) due to infrastructure and environmental constraints.
• Rapid transition to renewable energy — now one of the world's largest RE markets.

Coal

India's Coal Status

• 4th largest coal reserves in the world (~319 billion tonnes — proved + inferred).
• 2nd largest coal producer globally (after China; ahead of USA and Australia).
• Coal meets ~55% of India's primary energy needs (2024).
• ~70% of India's electricity generation is coal-based (thermal power).

Types of Coal

Gondwana Coal Fields — Most Important

Gondwana coal (Permian age, ~250–300 Ma) forms ~99% of India's total coal reserves:

Damodar Valley coalfields (Jharia + Raniganj + Bokaro + others): Concentrated in a narrow belt — India's most important coal-producing zone.

Tertiary Coal Fields (Northeast)

• Assam, Meghalaya, Nagaland, Arunachal Pradesh.
• Soft, high-sulphur coal; limited reserves.
• Makum coalfield (Assam) — important northeastern coal.

Lignite

• Tamil Nadu: Neyveli Lignite Corporation (NLC) — India's only large lignite mine; powers Neyveli Thermal Power Station.
• Rajasthan: Barmer (Giral lignite power plant).

Petroleum and Natural Gas

India's Petroleum Status

• India is the 3rd largest oil consumer globally but a minor producer.
• Domestic production covers only ~15% of consumption; ~85% imported (mainly from Middle East).
• Crude oil reserves (proved): ~600 million tonnes.

Major Oil-Producing Basins

Mumbai High = India's largest offshore oilfield; contributes ~50% of domestic crude production.

Natural Gas

• India produced ~93.6 BCM of gas (2023–24); significant import via LNG terminals.
• Major LNG Terminals: Dahej (Gujarat), Hazira (Gujarat), Kochi (Kerala), Ennore (Tamil Nadu), Dabhol (Maharashtra), Mundra (Gujarat).
• KG Basin D6: Was India's largest gas discovery (2002); production declined; now being redeveloped.
• Coal Bed Methane (CBM): Extracted from coal seams (Jharia, Raniganj); growing sector.
• Compressed Bio-Gas (CBG): Government pushing CBG from agricultural waste → SATAT scheme.

Petroleum Refineries (Major)

Digboi, Assam = oldest oil refinery in Asia (operational since 1901); India's oil history began here.

Pachpadra Refinery (HRRL): The HPCL Rajasthan Refinery Limited (HRRL) project at Pachpadra, Balotra district, Rajasthan (Balotra was carved out of Barmer in 2023 as a new district) is India's largest upcoming greenfield refinery (9 MMTPA capacity). It is a joint venture — HPCL holds 74% and the Government of Rajasthan holds 26%. The refinery will process crude from Barmer oilfields (Mangala, Bhagyam, Aishwarya — operated by Vedanta/Cairn) as well as imported crude via a dedicated pipeline from Mundra Port, Gujarat (~330 km pipeline). The project also includes a petrochemicals complex. As of March 2026, the refinery was in advanced construction phase with mechanical completion targeted for 2026–27. It will make Rajasthan self-sufficient in petroleum products and reduce transport costs from Gujarat refineries.

Iron Ore

• India has world's 4th largest iron ore reserves (~33 billion tonnes).
• India is a major exporter of iron ore (mainly to China, Japan, South Korea).
• Concentrated in the Peninsular plateau (Archean–Proterozoic rocks).

• Trap: "KGF is still operational" → Closed in 2001; Hutti mine is the operating one.
• Trap: "India is the world's largest thorium producer" → India has the world's largest reserves, but not necessarily the largest producer (production is limited).
• Trap: "Bhadla is in Jodhpur, Gujarat" → Rajasthan (Jodhpur district), not Gujarat.
• Trap: "PFBR uses uranium as primary fuel" → Stage 2 uses plutonium-239 (breeder), not natural uranium.
