Resources & industry: minerals, energy & industrial regions
India's mineral belts, energy mix and industrial regions for UPSC: distribution logic, location factors, and policy frameworks like MMDR and the NMP.
The geological logic of India's mineral wealth
India's metallic and coal wealth is overwhelmingly concentrated in the Peninsular shield, where Archaean and Proterozoic rocks of the Dharwar and Cuddapah systems host iron, manganese, copper, bauxite and mica, while Gondwana sedimentary basins hold the bulk of coal. The candidate must internalise that mineral distribution follows geology, not administrative boundaries.
Three great belts dominate:
- North-Eastern Plateau belt (Jharkhand, Odisha, West Bengal, Chhattisgarh): the richest, holding the Chota Nagpur plateau's iron ore (Singhbhum, Keonjhar, Mayurbhanj), coal (Jharia, Bokaro, Raniganj, Korba), copper (Ghatsila), mica and bauxite. Singhbhum copper and the Damodar valley coalfields anchor it.
- South-Western belt (Karnataka, Goa): iron ore of Bellary-Hospet and Kudremukh, manganese and the now-restricted Goan ore.
- North-Western belt (Rajasthan, Gujarat): non-ferrous and minor metals — copper (Khetri), lead-zinc (Zawar, Rampura-Agucha), and Rajasthan's marble and gypsum.
High-yield mineral facts
Iron ore: India holds large reserves of haematite (peninsular) and magnetite (Western Ghats). Odisha is the largest producer. Coal: over 95% is Gondwana coal (Permian), confined to the Damodar, Mahanadi, Son and Godavari basins; Tertiary coal occurs in the North-East (Assam, Meghalaya) and is high in sulphur. India is the world's second-largest coal producer and consumer. Bauxite: Odisha (Koraput, Kalahandi — the Panchpatmali deposits) leads; the Eastern Ghats are critical. Mica: the Koderma-Gaya-Hazaribagh belt of Jharkhand and Nellore in Andhra Pradesh. Manganese: Balaghat (MP), Nagpur-Bhandara (Maharashtra), Odisha.
Atomic and strategic minerals
The monazite sands of Kerala's coast (Kollam) supply thorium — central to India's three-stage nuclear programme. Uranium comes from Jaduguda (Jharkhand) and Tummalapalle (Andhra Pradesh). Copper, gold (Kolar, now closed; Hutti operating) and the rare-earth question feature increasingly. The Mines and Minerals (Development and Regulation) Act, 1957 (MMDR), amended in 2015 to mandate auction of mineral concessions and create the District Mineral Foundation (DMF) and National Mineral Exploration Trust (NMET), is the governing statute. The 2021 amendment removed the captive/merchant distinction and allowed seamless transfer of clearances.
Retain the producer-state rankings and the geological control: candidates routinely confuse iron-ore states (Odisha leads) with steel-plant locations. Distribution is dictated by ancient cratons; this is the spine on which industrial geography is built.
