Minerals and Energy Resources of India

Subject: Geography | Unit: Resources & Agriculture | Topic: Minerals & Energy Exam: AP Group 2 (APPSC)

Introduction

India's mineral wealth has shaped its industrial geography. The country possesses the largest iron ore reserves in Asia, is the world's largest mica producer, and has significant coal, bauxite, and manganese deposits. Energy resources — from coal (most abundant fossil fuel) to the rapidly expanding solar and wind sectors — power India's economy. For AP, minerals like limestone (Kurnool-Kadapa belt), barytes (Mangampet), mica (Nellore), and KG Basin natural gas are exam essentials.

Context

India's minerals are concentrated in three belts: the NE Plateau (Chotanagpur — iron, coal, manganese), the SW Plateau (Karnataka-Goa — iron, manganese), and the NW Region (Rajasthan — copper, zinc, mica). The 1991 economic reforms opened the mining sector to private and foreign investment. India imports ~85% of its crude oil but is a net exporter of refined petroleum products.

Mineral Classification

Major Minerals Distribution Table

Coal

• India's most abundant fossil fuel; 4th largest reserves globally
• 97% of reserves in: Damodar valley, Sone valley, Mahanadi valley, Godavari valley
• Gondwana coal (98%): 200 million years old — Jharia, Raniganj, Bokaro, Singrauli, Korba, Talcher
• Tertiary coal (2%): NE India, J&K, Neyveli lignite (TN)

Petroleum and Natural Gas

• Mumbai High (offshore): largest petroleum producer
• Digboi (Assam): India's oldest oilfield
• KG Basin (AP coast): Major gas discovery by Reliance (2002)
• India imports ~85% of crude oil needs
• HBJ Pipeline: Hazira-Bijaipur-Jagdishpur; 1,750 km; connects Gujarat gas to northern India

Energy Resources

AP Connection

• Limestone: Kurnool, Kadapa districts — major cement industry base (UltraTech, India Cements)
• Barytes: Kadapa (Mangampet — one of world's largest single deposits; 74 MT reserves); AP is India's #1 barytes producer
• Mica: Nellore belt — 2nd largest in India; 90 km strike, ~1,000 sq km
• Bauxite: Visakhapatnam, East Godavari (Araku hills) — high-grade deposits
• Manganese: Srikakulam, Vizianagaram districts
• KG Basin: Major natural gas and petroleum reserves off AP coast
• Uranium: Tummalapalle (Kadapa) — one of largest uranium deposits globally
• Thermal power: Ramagundam (now Telangana); Krishnapatnam, NTPC Simhadri
• AP has 48 types of minerals — one of India's most mineral-rich states

Key Points Summary

1. Iron ore: Odisha is largest producer (55%); India has Asia's largest reserves
2. Coal: 97% in Damodar, Sone, Mahanadi, Godavari valleys; Gondwana coal = 98%
3. Mica: India is world's #1 producer; Koderma (Jharkhand) = largest belt
4. Mumbai High = largest petroleum producer; Digboi = India's oldest oilfield
5. Neyveli (TN) = lignite; Anthracite only in J&K
6. Bauxite: Odisha largest (34.9%); used for aluminium
7. Thermal power provides ~60% of India's electricity
8. Nuclear power: Uranium from Jaduguda; Thorium from Kerala coast (world's largest reserves)
9. India targets 500 GW solar by 2030; currently 4th in global renewable capacity
10. HBJ Pipeline: 1,750 km; natural gas from Gujarat to north India
11. Hematite has ~70% iron content; Magnetite has ~72% but less available
12. Kolar Gold Fields (Karnataka) largely depleted; Hutti mines operational
13. AP has 48 minerals; Barytes #1 in India from Mangampet (Kadapa)
14. Nellore mica belt is India's 2nd largest
15. KG Basin is one of India's most important hydrocarbon basins

Exam Strategy

• State-mineral matching is the most common question type
• AP minerals: Limestone (Kurnool-Kadapa), Barytes (Kadapa), Mica (Nellore), Bauxite (Vizag-Araku)
• Coal types: Anthracite (J&K only) > Bituminous (most common) > Lignite (Neyveli, TN)
• First/largest: Mumbai High (largest oil), Koderma (largest mica), Odisha (largest iron/bauxite)
• Pipeline: HBJ = Hazira-Bijaipur-Jagdishpur = natural gas = 1,750 km
