Minerals and power are the base of every factory. Iron ore and coal make steel; bauxite makes aluminium; rivers and coal make electricity. Railways, roads, ports and pipelines then carry raw material in and goods out. Papers ask where each mineral is mined, which power project is in which state, which country helped build each steel plant, and which port lies on which coast.
On this page you will learn:
- Kinds of minerals and the main mining belts
- Coal ranks, coalfields, oil fields and pipelines
- Thermal, hydel, nuclear and green power
- Steel plants, textiles, sugar, cement and IT
- Railways, highways, ports, waterways and airports

Minerals, coal and oil
Rule in one line: the old rocks of the plateau hold the metals; coal lies in old river basins; oil lies in young rocks near the coasts.
| Mineral | Main belts and places | Remember |
|---|---|---|
| Iron ore | Odisha–Jharkhand (Badampahar, Gua, Noamundi); Durg–Bastar–Chandrapur (Bailadila); Ballari–Chitradurga–Chikkamagaluru–Tumakuru (Kudremukh); Maharashtra–Goa | Odisha has been the largest producer in recent years (Indian Bureau of Mines) |
| Manganese | Odisha, Madhya Pradesh (Balaghat), Maharashtra (Nagpur–Bhandara), Karnataka | About 10 kg is needed for one tonne of steel |
| Bauxite | Odisha (Panchpatmali, Koraput); Amarkantak plateau, Maikal hills, Bilaspur–Katni | Ore of aluminium; Odisha is the largest producer |
| Copper | Balaghat (Malanjkhand, MP); Khetri (Rajasthan); Singhbhum (Jharkhand) | India produces less than it needs |
| Mica | Koderma–Gaya–Hazaribagh (Jharkhand); Ajmer (Rajasthan); Nellore (Andhra Pradesh) | Splits into thin sheets; used in electrical goods |
| Gold | Hutti (Raichur, Karnataka); Kolar Gold Fields (Karnataka) closed in 2001 | Karnataka gives most of India's mined gold |
| Tin, lead–zinc, lignite | Tin: Dantewada–Bastar (Chhattisgarh). Lead–zinc: Zawar (Rajasthan). Lignite: Neyveli (Tamil Nadu) | Chhattisgarh is the only tin-producing state; Tamil Nadu has the largest lignite reserves |
QUICK CHECK
PYQ · PPSC PCSEB 2018 — Which of these are correct: 1. Chhattisgarh is the only Tin producing state in India. 2. India is the largest producer of Coffee in the world. 3. Rajasthan is the largest producer of Mica in India. 4. Tamil Nadu has the largest reserves of Lignite coal in India.
Tap an option to answer
Answer: B — 1 and 4
1 and 4 are textbook facts (Bastar tin; Neyveli lignite). Statement 2 is false — Brazil grows the most coffee — so options A and C fall away, and the answer is 1 and 4. Statement 3 is false too: in recent Indian Bureau of Mines data, Andhra Pradesh (not Rajasthan) is the leading mica producer.
COAL RANKS: MORE PRESSURE AND TIME, MORE CARBON
- 1PeatPartly rotted plants; lowest carbon, much moisture, burns with smoke
- 2LigniteBrown coal; Neyveli in Tamil Nadu
- 3Bituminous (coking coal)Most used; the coking type is burnt to coke for blast furnaces
- 4AnthraciteHardest, highest-grade coal; little in India
QUICK CHECK
PYQ · PPSC NT 2020 — Arrange coal in increasing order of its stage of formation and carbon content, and choose the correct option. I. Peat II. Graphite III. Coking coal IV. Lignite
Tap an option to answer
Answer: B — I, IV, III, II
Peat has the least carbon, then lignite, then bituminous coking coal; graphite, nearly pure carbon, comes last: I, IV, III, II.
| Oil, gas and pipelines | Key facts |
|---|---|
| Oil fields | Mumbai High (offshore, largest); Ankleshwar and Kalol (Gujarat); Digboi, Naharkatiya (Assam); Krishna–Godavari basin (gas) |
| Refineries | Jamnagar (Gujarat) is the largest refining hub; in Punjab, the Guru Gobind Singh Refinery at Bathinda gets crude by pipeline from Mundra |
| Oil pipeline | Naharkatiya–Guwahati–Barauni, built by Oil India — the first long crude pipeline; Salaya–Mathura in the west |
| Gas pipeline | HBJ: Hazira–Vijaipur–Jagdishpur, by GAIL; it feeds fertiliser and power plants in the north |
Power: thermal, hydel, nuclear and green
Rule in one line: thermal plants sit near coal or ports; hydel plants sit where a river falls through the hills.
Coal-based thermal power still gives most of India's electricity. Big thermal stations stand on the coalfields — Korba (Chhattisgarh), Singrauli (Uttar Pradesh) and Vindhyachal (Madhya Pradesh), Talcher (Odisha) — or near ports that bring in fuel, such as Sikka (Gujarat) and Ennore (Tamil Nadu). Parli is in Maharashtra. Punjab's thermal plants include Ropar, Lehra Mohabbat, Rajpura and Talwandi Sabo.

Industries: steel, textiles, sugar, cement and IT
Rule in one line: heavy industry goes to its raw material; light industry goes to its market.

KEY TERM
Nodal and footloose industries
A nodal industry feeds many others. The Petro Chemical Industry is the nodal industry for synthetic textiles, because it makes the polyester and nylon fibres. A footloose industry can be set up almost anywhere: it is not tied to one raw material, uses small parts, makes goods in small quantity and causes little pollution — electronics is an example. So a statement that 'they are dependent on specific raw material' is NOT true of footloose industries.

Traps and practice
Last revision — where the options try to fool you.
COMMON TRAPS
- Ganguwal and Kotla are in Punjab, not Himachal; Luhri, Khab, Chamera and Nathpa Jhakri are in Himachal.
- Dehar power house goes with the Pandoh dam (Beas–Sutlej Link), not with Nangal.
- A pair like Sutlej Dam – Chenab is wrong: the Sutlej and the Chenab are different rivers. Maheshwar – Narmada, Tungabhadra – Krishna and Hirakud – Mahanadi are right.
- Bhilai and Bokaro — USSR; Rourkela — West Germany; Durgapur — UK. No plant was built with Sweden.
- Kochi is a west-coast port; Haldia, Paradip and Tuticorin are on the east coast.
- East–West corridor = Silchar–Porbandar, not Imphal or Rajkot.
- Sugar is agro-based; cement, steel and petrochemicals are mineral-based.
CHECK YOURSELF
Why are most of India's steel plants in and around the Chota Nagpur plateau?
Show answer
Steel needs huge amounts of iron ore, coking coal and manganese, which are heavy and cheap to carry only over short distances. The Chota Nagpur region has all three close together, plus water from the Damodar and Subarnarekha and cheap labour, so Jamshedpur, Bokaro, Rourkela, Durgapur and Burnpur grew there.
