India - Minerals, Energy and Industries PYQs – Geography, SSC & Railway

Non-ferrous metallic minerals do not contain iron. Copper, zinc, and lead are all non-ferrous and India has limited reserves of these, making them scarce.
Option 1 — Iron is ferrous; Coal is not a metallic mineral.
Option 3 — Manganese is ferrous; Limestone is non-metallic.
Option 4 — Mica, Dolomite, Felspar are all non-metallic minerals.

1 — Correct. Sucrose content of sugarcane falls during transit, which is why mills are located close to cane fields.
2 — Correct. The sugar industry is seasonal, depending on the cane crushing season (typically October to May).
3 — Wrong. The sugar industry has, in fact, been very successfully managed under the cooperative model (especially in Maharashtra).
4 — Correct. Maharashtra and Uttar Pradesh lead, with Tamil Nadu being a major southern producer.
Hence statements 1, 2, and 4 are correct.

A unique feature of India's textile industry is that it is self-reliant across the entire value chain — from fibre (cotton, silk, jute, man-made fibres) to yarn, fabric, dyeing, processing and finished garments.
It does not focus only on raw material exports; it does not import final products to fill domestic demand; and it serves both export and large domestic markets.
Hence the correct option is: It is self-reliant across the full value chain.

The Damodar Valley (Jharkhand and West Bengal) is India's most important coal-bearing region and is located on the eastern part of the Chota Nagpur (North-Eastern) Plateau.
Major fields: Jharia, Raniganj, Bokaro, Karanpura.

Statement 1 — Incorrect. India imports nearly 100% of its potash requirement (mainly from Canada, Russia, Belarus). Not self-sufficient.
Statement 2 — Correct. Urea is the most widely produced/used nitrogenous fertilizer in India.
Statement 3 — Correct. Fertilizer production rose sharply after the Green Revolution (late 1960s).
Statement 4 — Incorrect. Gujarat is one of the largest producers of fertilizers in India (IFFCO Kalol, GNFC, GSFC). Kerala (FACT) is also a notable producer.
Hence only 2 and 3 are correct.

• Indian Minerals (Geography/Economy):
• India has rich deposits of non-metallic minerals like limestone, mica, gypsum, and phosphates.
• These are vital for major industries like cement, fertilizers, glass, ceramics, and construction.
• India is a major global producer of mica and is among top producers of limestone.
• Options A, B, D are factually incorrect.

Correct Answer: Option 2 – Metallurgical
The metallurgical industry (steel and iron manufacturing) is by far the largest consumer of manganese in India — accounting for over 90% of manganese consumption. Manganese is an essential ingredient in steel production: it acts as a deoxidizer and desulfurizer, improves hardness, strength, and wear resistance of steel. Every tonne of steel requires approximately 6–9 kg of manganese. India is a major producer of manganese ore (Odisha, Madhya Pradesh, Maharashtra, Karnataka).
Option 1 (Photography): Photography uses silver halides; manganese has no significant application in photography.
Option 3 (Match): The match industry historically used phosphorus compounds; some formulations use manganese dioxide as an oxidizer, but this is a negligible fraction of total manganese consumption.
Option 4 (Leather): Leather tanning uses chromium and vegetable tannins; not significant manganese consumption.

Correct Answer: Option 3 – It plays a key role in industrial output and jobs
The textile industry is one of India's oldest and largest industries. It contributes approximately 2.3% to GDP, 7% of industrial output value, and 12% of India's export earnings. It employs over 45 million people directly and 60 million indirectly — making it the second largest employer after agriculture. India is the world's second largest producer of textiles and garments.
Option 1 (Dependent on foreign raw materials): India's textile industry is largely self-sufficient in raw materials — cotton (2nd largest producer globally), jute (largest producer), silk, and wool are domestically available. Some specialty fibers are imported but it is NOT predominantly dependent on foreign raw materials.
Option 2 (Not involved in foreign exchange earnings): Textiles and apparel are among India's top export categories, earning significant foreign exchange — this statement is factually incorrect.
Option 4 (Only manufactures low-value goods): India produces high-value textiles including silk, fine cotton, technical textiles, and branded apparel for export — this statement is incorrect.

Correct Answer: Option 1 – Monazite, thorium, and bauxite clay
Kerala's coastal regions, especially in Kollam, Alappuzha, and Thrissur, are rich in monazite (a thorium-bearing mineral). Kerala is one of India's primary sources of thorium. The state also has deposits of bauxite clay, ilmenite (titanium ore), and rutile.
Option 2 (Iron ore, coal, gold): These are primarily found in states like Jharkhand, Odisha, Chhattisgarh, and Karnataka.
Option 3 (Copper, limestone, gypsum): Found mainly in Rajasthan, Madhya Pradesh, and Andhra Pradesh.
Option 4 (Uranium, petroleum, mica): Uranium in Jharkhand; petroleum in Gujarat/Assam; mica in Jharkhand/Rajasthan.

Correct Answer: Option 2 – The region has high mineral availability, along with water resource and labor availability
The Chota Nagpur Plateau region (covering Jharkhand, parts of Odisha, West Bengal, and Chhattisgarh) is India's most mineral-rich zone — often called the 'Ruhr of India.' The iron and steel industry is concentrated here due to: abundant raw materials — high-grade iron ore (Jharkhand, Odisha), coking coal (Jharia, Raniganj coalfields), manganese, limestone, and dolomite; water availability — from the Damodar River system and other rivers; cheap labour ; and proximity to raw material sources ( minimising transportation costs). Major steel plants: Tata Steel (Jamshedpur), SAIL plants at Bokaro, Rourkela, Durgapur, Bhilai .
Option 1 (Cold climate): The region has a subtropical/tropical climate — not a 'cold climate.' Climate is not a locational factor for iron/steel industries.
Option 3 (Close to international ports): The Chota Nagpur Plateau is an inland region — not close to international ports. Coastal steel plants (like Vizag, Ennore) are near ports, but Chota Nagpur's advantage is minerals, not ports.
Option 4 (Mainly agricultural): The region is characterised by mineral wealth and tribal communities — it is not primarily known for agriculture.

Correct Answer: Option 1 – Hematite
The Bailadila iron ore deposits in Dantewada district of Chhattisgarh contain high-grade Hematite ( Fe₂O ₃) iron ore with iron content of 64–68%. Bailadila is one of the largest high-grade iron ore deposits in Asia, spread across 14 deposits covering about 28 sq km. The ore is mined by NMDC (National Mineral Development Corporation) and exported to Japan and other countries. Bailadila ore is renowned for its exceptional purity and low phosphorus/ sulphur content.
Option 2 (Siderite): FeCO ₃ — a low-grade iron ore containing about 48% iron; found in some European deposits; not the ore mined at Bailadila .
Option 3 (Limonite): FeO (OH)· nH₂O — a low-grade hydrated iron ore; not the ore at Bailadila .
Option 4 (Magnetite): Fe₃O ₄ — highest iron content (~72%) iron ore; found at Kudremukh (Karnataka) and some other Indian deposits; Bailadila specifically has Hematite.

Correct Answer: Option 4 – 1, 2, 3 and 4
All four products are part of India's petrochemical industry, which uses petroleum and natural gas-derived hydrocarbons as feedstock:
1. Polymers: Plastics (PET, PP, PE) — core petrochemical products for packaging, automotive, construction.
2. Synthetic fibres : Polyester, nylon, acrylic — produced from petrochemical intermediates like ethylene glycol.
3. Elastomers: Synthetic rubbers (SBR, NBR, EPDM) — petrochemical-derived materials for tyres and industrial applications.
4. Surfactant intermediates: Linear alkylbenzene (LAB) for detergents — also derived from petroleum-based feedstock.
India's Petroleum, Chemicals and Petrochemicals Investment Region (PCPIR) policy covers all these categories. Therefore all four are part of the petrochemical industry.

Correct Answer: Option 4 – 1, 2, 3 and 4
All four products are part of India's petrochemical industry, which is a downstream sector of the oil and gas industry using hydrocarbons (ethylene, propylene, benzene, etc.) as feedstock:
1. Polymers: Plastics, PET, polypropylene, polyethylene — core petrochemical products used in packaging, construction, automotive industries.
2. Synthetic fibres : Polyester, nylon, acrylic — produced from petrochemical intermediates like ethylene glycol and terephthalic acid.
3. Elastomers: Synthetic rubbers (SBR, NBR, EPDM) — petrochemical-derived materials for tires, seals, and automotive applications.
4. Surfactant intermediates: Linear alkylbenzene (LAB) and other intermediates for detergents/surfactants — derived from petroleum-based chemicals.
India's Petroleum, Chemicals and Petrochemicals Investment Region (PCPIR) policy covers all these product categories.

Correct Answer: Option 3 – Madhya Pradesh
The Omkareshwar Floating Solar Power Project, located on the Omkareshwar reservoir (Narmada River) in Khandwa district, Madhya Pradesh, is the world's largest floating solar power plant. With a planned capacity of 600 MW, Phase 1 (278.5 MW) was inaugurated in 2023 by the Government of Madhya Pradesh in partnership with the World Bank.
Option 1 (Tamil Nadu): Has significant solar capacity but not the world's largest floating plant.
Option 2 (Andhra Pradesh): Does not host the world's largest floating solar project.
Option 4 (Gujarat): Hosts the Dhuvaran Solar Plant and other projects but not this record-holder.
