Summary
Chapter 5 of India: People and Economy covers India's mineral resources (ferrous, non-ferrous, non-metallic) and energy resources (conventional fossil fuels, nuclear energy, and non-conventional sources like solar, wind, and geothermal), along with their spatial distribution across three major mineral belts.
India's varied geological structure yields a rich variety of mineral resources, most of which occur in the peninsular plateau region. Minerals are classified as metallic (ferrous and non-ferrous) and non-metallic. Three broad mineral belts span the country — the North-Eastern Plateau (Jharkhand, Odisha, West Bengal, Chhattisgarh), the South-Western Plateau (Karnataka, Goa, Tamil Nadu, Kerala), and the North-Western Region (Rajasthan, Gujarat). India holds the largest iron ore reserve in Asia, with haematite and magnetite as the two main types. Coal, petroleum, and natural gas form the conventional energy base, while nuclear, solar, wind, tidal, geothermal, and bio-energy are non-conventional alternatives. Conservation of exhaustible minerals and a shift to renewable energy are essential for sustainable development.
Key points & formulas
- 01Minerals are classified into metallic (ferrous and non-ferrous) and non-metallic; all are exhaustible and unevenly distributed with an inverse relationship between quality and quantity.
- 02Three major mineral belts: North-Eastern Plateau (iron ore, coal, manganese, bauxite, mica), South-Western Plateau (iron ore, manganese, bauxite; lacks coal except Neyveli lignite), and North-Western Region (copper, zinc, building stones, gypsum, petroleum in Gujarat).
- 03India holds the largest iron ore reserve in Asia; about 95% of reserves are in Odisha, Jharkhand, Chhattisgarh, Karnataka, Goa, Telangana, Andhra Pradesh, and Tamil Nadu.
- 04About 80% of India's coal is bituminous and non-coking grade; the Damodar Valley fields (Jharia, Raniganj, Bokaro) are the most important, with Jharia being the largest coal field.
- 05Petroleum: Digboi (Assam) was the only producing region before ONGC was set up in 1956; Mumbai High was discovered in 1973 with production starting in 1976; new reserves found in Krishna-Godavari and Kaveri basins.
- 06Nuclear energy uses uranium (Singhbhum copper belt, Rajasthan) and thorium (monazite in Kerala and Tamil Nadu); the world's richest monazite deposits are in Palakkad and Kollam districts of Kerala.
- 07Non-conventional sources — solar, wind, tidal, geothermal (plant at Manikaran, Himachal Pradesh), and bio-energy — are renewable and environment-friendly alternatives to exhaustible fossil fuels.
- 08Conservation strategies include using scrap metals (especially copper, lead, zinc where reserves are meagre), developing renewable energy, using substitutes for scarce metals, and reducing export of strategic minerals.
Frequently asked questions
01What are the two main categories of minerals and how are they further classified?
Minerals are grouped into metallic and non-metallic. Metallic minerals are further divided into ferrous (containing iron, e.g., iron ore, manganese) and non-ferrous (no iron content, e.g., copper, bauxite). Non-metallic minerals include organic types (fossil fuels like coal and petroleum) and inorganic types (mica, limestone, graphite).
02What are the three characteristics of minerals mentioned in the chapter?
First, minerals are unevenly distributed over space. Second, there is an inverse relationship between quality and quantity — good quality minerals are less in quantity compared to low quality minerals. Third, all minerals are exhaustible over time and cannot be replenished immediately, so they must be conserved.
03Name the three broad mineral belts in India and the key minerals found in each.
The North-Eastern Plateau Region (Jharkhand, Odisha, West Bengal, Chhattisgarh) has iron ore, coal, manganese, bauxite, and mica. The South-Western Plateau Region (Karnataka, Goa, Tamil Nadu, Kerala) is rich in ferrous metals, bauxite, iron ore, and manganese but lacks coal except Neyveli lignite. The North-Western Region (Rajasthan and Gujarat) has copper, zinc, building stones, gypsum, and petroleum.
04What are the two main types of iron ore found in India, and which states hold 95% of the reserves?
The two main types are haematite and magnetite. About 95% of total iron ore reserves are in Odisha, Jharkhand, Chhattisgarh, Karnataka, Goa, Telangana, Andhra Pradesh, and Tamil Nadu. India holds the largest iron ore reserve in Asia.
05Which is the largest coal field in India and where are Gondwana coal fields located?
Jharia is the largest coal field, followed by Raniganj. The most important Gondwana coal fields are in the Damodar Valley (Jharkhand-Bengal coal belt), including Raniganj, Jharia, Bokaro, Giridih, and Karanpura. Over 97% of coal reserves in India occur in the valleys of Damodar, Sone, Mahanadi, and Godavari.
06When was the Oil and Natural Gas Commission set up, and what was the significance of Mumbai High?
The Oil and Natural Gas Commission was set up in 1956. Before that, Digboi in Assam was the only oil-producing region. Mumbai High, located 160 km off Mumbai, was discovered in 1973 and production commenced in 1976. It is a major offshore oilfield in the Arabian Sea.
07What are the uses of natural gas as mentioned in the chapter?
Natural gas is used as a domestic and industrial fuel, for generating electricity in the power sector, for heating in industries, and as a raw material in chemical, petrochemical, and fertiliser industries. With expansion of gas infrastructure it is also used as CNG (compressed natural gas) for transport and PNG (piped natural gas) for cooking at homes.
08What minerals are used for generating nuclear energy and where are they found in India?
Uranium and thorium are the important minerals for nuclear energy. Uranium occurs in Dharwar rocks, particularly in the Singhbhum Copper Belt, and also in Rajasthan (Udaipur, Alwar, Jhunjhunu), Chhattisgarh, Maharashtra, and Himachal Pradesh. Thorium is obtained from monazite and ilmenite in beach sands along Kerala and Tamil Nadu coasts; world's richest monazite deposits are in Palakkad and Kollam districts of Kerala.
09Name the nuclear power stations in India mentioned in the chapter.
The important nuclear power projects are Tarapur (Maharashtra), Rawatbhata near Kota (Rajasthan), Kalpakkam (Tamil Nadu), Narora (Uttar Pradesh), Kaiga (Karnataka), and Kakarapara (Gujarat). The Atomic Energy Commission was established in 1948 and the Atomic Energy Institute at Trombay was set up in 1954, later renamed the Bhabha Atomic Research Centre in 1967.
10Which state is the largest producer of bauxite and where are the major deposits?
Odisha is the largest producer of bauxite, with Kalahandi and Sambalpur as leading areas, followed by Bolangir and Koraput. Other major producers include Jharkhand (Lohardaga), Gujarat (Bhavanagar, Jamnagar), Chhattisgarh (Amarkantak plateau), Madhya Pradesh (Katni-Jabalpur, Balaghat), and Maharashtra.
11How is solar energy more effective than other sources according to the chapter?
The chapter states that solar energy is 7% more effective than coal or oil based plants and 10% more effective than nuclear plants. It is cost competitive, environment friendly and easy to construct. The western part of India, particularly Gujarat and Rajasthan, has greater potential for solar energy development.
12Where is India's geothermal energy plant located and what is bio-energy?
India has commissioned a geothermal energy plant at Manikaran in Himachal Pradesh. Bio-energy refers to energy derived from biological products including agricultural residues, municipal, industrial and other wastes; it can be converted into electrical energy, heat, or cooking gas. The Okhla project in Delhi converts municipal waste into energy.
