Mineral and Energy Resources and the Location of Industries in India

Why resource geography matters

India's industries, power stations and exports depend on where its minerals and fuels lie. GS Paper 1 asks about the distribution of key natural resources and the factors responsible for the location of primary, secondary and tertiary industries in India and the world. Most of India's metallic minerals and coal lie in the ancient rocks of the Peninsular Plateau, especially the Chotanagpur plateau and the Odisha–Chhattisgarh–Jharkhand belt, often called the "mineral heartland". Petroleum and natural gas come from sedimentary basins along the coasts and in Assam.

Mineral belts of India

Key metallic minerals

• Iron ore: India is among the world's top producers. Two main ores are haematite (highest quality in India by use) and magnetite (richest in iron content, up to 70 per cent). Odisha is now the largest producer, followed by Chhattisgarh, Karnataka and Jharkhand. Important mines: Bailadila (Chhattisgarh), Keonjhar–Barbil (Odisha), Noamundi (Jharkhand), Kudremukh and Bellary (Karnataka). Goa's ore is exported through Mormugao.
• Manganese: needed for steel; Odisha, Madhya Pradesh (Balaghat), Maharashtra and Karnataka.
• Bauxite (aluminium ore): found in laterite caps; Odisha (Koraput, Kalahandi – the Panchpatmali mines of NALCO), Gujarat, Jharkhand, Chhattisgarh (Amarkantak plateau).
• Copper: Rajasthan (Khetri), Jharkhand (Singhbhum), Madhya Pradesh (Malanjkhand, the largest copper mine). India imports much of its copper.
• Mica: Jharkhand (Koderma–Hazaribagh), Andhra Pradesh (Nellore), Rajasthan – once a world leader.
• Gold: Karnataka's Hutti mines (Kolar is now closed); India imports most of the gold it uses.
• Critical minerals: lithium, cobalt, rare earths and graphite are vital for batteries and clean energy. In 2023 India listed 30 critical minerals, began auctioning blocks, and announced finds of lithium in Reasi (Jammu and Kashmir); the National Critical Mineral Mission (2025) aims to secure supply.

Energy resources

Coal

Coal is India's main source of commercial energy and produces about 70 per cent of its electricity. India produced over 1 billion tonnes for the first time in 2024–25.

• Gondwana coal (about 250 million years old, mostly bituminous) – about 98 per cent of reserves, in the river valleys of the Damodar (Jharia, Raniganj, Bokaro), Mahanadi (Talcher, Ib valley), Son (Singrauli) and Godavari–Wardha (Singareni, Chandrapur).
• Tertiary coal – younger and lower in quality; Assam, Meghalaya, Arunachal.
• Lignite (brown coal) – Neyveli in Tamil Nadu, plus Gujarat and Rajasthan.
• Jharkhand, Odisha and Chhattisgarh hold the largest reserves; Indian coal has high ash, so coking coal for steel is imported.

Petroleum and natural gas

India imports about 85–88 per cent of its crude oil. Domestic production comes from:

• Assam – Digboi (India's oldest oilfield and refinery, 1901), Naharkatiya, Moran.
• Gujarat – Ankleshwar, Kalol, Cambay basin.
• Mumbai High offshore – the largest producing field, found in 1974.
• Krishna–Godavari basin (gas, including the KG-D6 field) and the Barmer basin of Rajasthan (Mangala field).
• The Jamnagar refinery complex in Gujarat is the world's largest single-site refinery.

Non-conventional and nuclear energy

• Renewables: India's installed non-fossil capacity crossed 50 per cent of total power capacity in June 2025, five years ahead of its 2030 target. Top states for solar are Rajasthan, Gujarat and Karnataka; for wind, Gujarat and Tamil Nadu. Bhadla Solar Park (Rajasthan) and the Khavda renewable energy park (Gujarat, planned for about 30 GW) are among the largest in the world.
• Nuclear: India follows a three-stage programme – pressurised heavy water reactors on natural uranium; fast breeder reactors (the Kalpakkam PFBR began core loading in 2024); and thorium-based reactors, since India has large monazite sands in Kerala and Odisha. Uranium comes from Jaduguda (Jharkhand) and Tummalapalle (Andhra Pradesh).
• Hydropower: large potential in the Himalaya and the north-east; projects such as Tehri, Bhakra, Subansiri Lower.

Factors of industrial location

Alfred Weber's least-cost theory (1909) said industries locate where the total cost of transporting raw materials and finished goods is lowest. Industries using weight-losing raw materials (like iron ore and coal for steel, or sugarcane for sugar) locate near raw materials; industries whose products gain weight or are perishable locate near markets.

Main factors:

• Raw materials – steel near iron ore and coal; sugar mills near cane fields; cement near limestone.
• Power – aluminium smelters need huge amounts of cheap electricity (Renukoot near Rihand dam).
• Labour – skilled labour in Bengaluru (IT), cheap labour for textiles and garments (Tiruppur).
• Market – petroleum refineries and consumer goods near large cities.
• Transport and ports – industries cluster along railways and near ports such as Mumbai, Chennai and Visakhapatnam.
• Water, capital, government policy (SEZs, PLI schemes, tax incentives, industrial corridors) and agglomeration benefits.

Major industries and their location

Industrial regions and corridors

India's main industrial regions are the Mumbai–Pune, Hooghly, Bengaluru–Chennai, Gujarat (Ahmedabad–Vadodara), Chotanagpur, Visakhapatnam–Guntur, Gurugram–Delhi–Meerut and Kollam–Thiruvananthapuram belts. The government is building 11 industrial corridors, including the Delhi–Mumbai Industrial Corridor linked to the Western Dedicated Freight Corridor, and in 2024 approved 12 new industrial smart cities under the National Industrial Corridor Development Programme.

Primary, secondary and tertiary activities across regions

The syllabus also asks about the location of primary activities (farming, fishing, forestry, mining), secondary activities (manufacturing) and tertiary activities (services). Primary activities are tied tightly to nature: rice in the wet deltas, wheat in the irrigated north-west, plantations on hill slopes, fishing along the continental shelf, and mining wherever the ore lies. Secondary activities are freer and follow the cost factors above. Tertiary activities – banking, IT, trade, tourism, health care – follow people, skills and connectivity, which is why they concentrate in large cities and why services now provide more than half of India's GDP.

Problems of the mineral heartland

The areas richest in minerals are often among India's poorest. Mining in Jharkhand, Odisha and Chhattisgarh has displaced tribal communities, damaged forests and rivers, and created pollution, while much of the value is captured elsewhere – a pattern sometimes called the "resource curse". Remedies include the District Mineral Foundation (DMF), funded by miners since 2015 to spend on affected areas through the PMKKKY scheme; transparent auctions of mining leases under the amended MMDR Act; consent of gram sabhas under PESA; and the Supreme Court's 2013 Niyamgiri judgment, which let the Dongria Kondh decide on bauxite mining in their sacred hills.

Mains practice question

Why are the iron and steel industries of India mostly located in the Chotanagpur region? Explain how new factors are changing industrial location in India. (250 words)

Answer framework

• Intro: Weber's least-cost theory.
• Chotanagpur: iron ore, coal (Damodar valley), manganese, limestone, water, rail link to Kolkata port.
• New factors: coastal plants on imported coking coal (Visakhapatnam), private plants near markets, SEZs, corridors, PLI, skilled labour hubs.
• Conclusion: footloose industries, balanced regional growth.
