NDA Geography · Indian Geography — Economy, Resources and Transport
Minerals and Mining
The mineral-to-state and mine-to-mineral pairs of India, the metallic vs non-metallic split, and the coal and copper belts.
Why this matters
About 14 PYQs, skewing HARD because so many are four-way match-the-list questions (place to mineral, mineral to leading state). The payoff is pure recall: a handful of mine-to-mineral anchors (Zawar zinc, Bailadila iron, Ghatsila copper, Malanjkhand copper), the leading-producer states, and the coalfield geography. Drill the anchor pairs and the match-lists become solvable by elimination.
Concept 1 of 5
Classifying minerals — metallic, non-metallic, energy
Intuition
Minerals split into broad classes, and the exam tests the boundary. METALLIC minerals yield metals on smelting — iron, copper, bauxite (aluminium), manganese, gold. NON-METALLIC minerals contain no metal you extract for use — mica, limestone, gypsum, dolomite. A separate ENERGY/fuel class covers coal and petroleum. The classic question hands you a list with one impostor; knowing which class each belongs to is the whole answer.
Definition
- Metallic — yield a metal: iron ore, copper, bauxite, manganese, gold, zinc, nickel.
- Non-metallic — no extractable metal: mica, limestone, gypsum, dolomite, graphite, fluorspar.
- Energy / fuel minerals — coal, petroleum, natural gas, uranium.
- Mica is the staple non-metallic answer; it is used mainly in the electrical and electronics industry (an excellent insulator).

Concept 2 of 5
Leading producer states by mineral
Intuition
Half the chapter's match-lists are 'mineral → leading state' grids. A core set of anchors solves most of them: Madhya Pradesh leads manganese, Rajasthan leads gypsum (and is the copper state with MP), Odisha leads magnetite/chromite, Karnataka leads limestone and iron. Memorise the leading state for the half-dozen most-tested minerals and the four-way codes fall by elimination.
Definition
- Manganese → Madhya Pradesh (Balaghat belt).
- Gypsum → Rajasthan.
- Limestone → Karnataka (among the leaders).
- Magnesite → Uttarakhand.
- Copper → Rajasthan and Madhya Pradesh (Khetri in Rajasthan, Malanjkhand in MP) per the Ministry of Mines.
- Graphite → Odisha/Arunachal; Fluorspar → Gujarat; Nickel → Odisha.
| Mineral | Leading state(s) |
|---|---|
| Manganese | Madhya Pradesh NDA 2023 — MP is the leading manganese producer. |
| Copper | Rajasthan and Madhya Pradesh NDA 2025 — per the Ministry of Mines, Rajasthan + MP. |
| Gypsum | Rajasthan |
| Magnesite | Uttarakhand |
| Limestone | Karnataka |

Concept 3 of 5
Mine and place to mineral pairs
Intuition
Specific mines anchor the place-to-mineral match-lists. The most-tested pairs: Zawar (Rajasthan) = zinc, Bailadila (Chhattisgarh) = iron ore, Ghatsila (Jharkhand) = copper, Malanjkhand (MP) = copper, Khetri = copper, Kudremukh = IRON (not bauxite — the classic trap), Lakwa (Assam) = petroleum. Lock these anchors and the four-way codes are solvable.
Definition
- Zawar (Rajasthan) → Zinc; Bailadila (Chhattisgarh) → Iron ore; Ghatsila (Jharkhand) → Copper.
- Malanjkhand (MP) → Copper; Khetri (Rajasthan) → Copper.
- Kudremukh (Karnataka) → Iron ore (the trap pairs it wrongly with bauxite).
- Lakwa (Assam) → Petroleum; Kalakot → Coal.
- Match-list anchors (NDA 2025): Balaghat → Manganese, Bilaspur → Iron-ore, Ballary → Bauxite.
| Mine / place | Mineral |
|---|---|
| Zawar | Zinc |
| Bailadila | Iron ore |
| Ghatsila | Copper |
| Kudremukh | Iron ore (NOT bauxite) NDA 2023 — 'Kudremukh : Bauxite' is the wrongly-matched pair; it is iron ore. |
| Lakwa | Petroleum |

Concept 4 of 5
Iron-ore grades and critical minerals
Intuition
Two niche-but-tested facts sit here. IRON-ORE grades: magnetite is the highest-grade 'black ore' with 60–70% iron and magnetic properties; haematite is the red ore. And the new CRITICAL-minerals theme: rare-earths and metalloids used in solar photovoltaic cells — tellurium and gallium go into PV cells, while neodymium and dysprosium are rare-earth magnet metals NOT used in standard solar panels.
Definition
- Magnetite — the black ore of iron, 60–70% pure iron, and magnetic: all three statements hold.
- Haematite — the red ore of iron.
- Solar PV critical minerals — tellurium and gallium are used in photovoltaic cells; neodymium and dysprosium are rare-earth magnet metals (wind turbines, motors), NOT in standard PV cells.
| Mineral | Key fact |
|---|---|
| Magnetite | Black ore, 60–70% iron, magnetic NDA 2017 (Sep) — all three statements about magnetite are correct. |
| Haematite | Red ore of iron |
| Tellurium, Gallium | Used in solar PV cells |
| Neodymium, Dysprosium | Rare-earth magnets — NOT in PV cells NDA 2026 — Nd and Dy are the pair NOT used for photovoltaic cells. |

Concept 5 of 5
Coalfields and coal-reserve geography
Intuition
Coal questions test reserves order and field locations. By proved reserves the order is Jharkhand > Chhattisgarh > Odisha > West Bengal. Most coalfields cluster in the Damodar valley (Jharia, Raniganj, Bokaro) of Jharkhand and West Bengal — so the trick is spotting the field that is NOT in Jharkhand (Umaria is in Madhya Pradesh). The Kalakot tertiary coalfield is the odd one out — it lies in the Himalayan mountain region, not the peninsular Gondwana basins.
Definition
- Proved coal-reserve order: Jharkhand > Chhattisgarh > Odisha > West Bengal.
- Jharkhand coalfields: Jharia, Bokaro, Ramgarh, Deogarh. Umaria is in Madhya Pradesh (the impostor in a 'not in Jharkhand' list).
- Kalakot tertiary coalfield → Himalayan mountain region (tertiary coal, not Gondwana).
| Item | Fact |
|---|---|
| Proved reserves order | Jharkhand > Chhattisgarh > Odisha > West Bengal NDA 2019 — decreasing order of proved coal reserves. |
| Coalfield NOT in Jharkhand | Umaria (Madhya Pradesh) NDA 2021 (Sep) — Umaria is in MP, the odd one out. |
| Kalakot tertiary coalfield | Himalayan mountain region NDA 2017 (Sep) — tertiary coal of the Himalaya. |
