Copper
Geography › Mineral and Energy Resources · Topic 21.11
Copper is a reddish, ductile metal and one of the best conductors of heat and electricity, used in wiring, motors, electronics, vehicles, pipes and, increasingly, in renewable energy and electric vehicles. Its main ores are chalcopyrite, malachite and azurite. Chile is by far the largest producer, followed by Peru, the Democratic Republic of the Congo and China. In India the Khetri belt in Rajasthan, Malanjkhand in Madhya Pradesh and Singhbhum in Jharkhand are the main sources.

Where Does It Fit?
This is the eleventh topic of the macro on mineral and energy resources. The previous topic covered four alloying metals, and this one covers copper, the most widely used of the non-ferrous metals after aluminium. The next topic covers lithium and strategic minerals. Previous topic: Tungsten, Nickel, Molybdenum and Cobalt. Next topic: Lithium and Strategic Minerals.
What Is Copper, and Where Is It Used?
In short: copper conducts electricity better than any common metal except silver, so it is the metal of power grids.
- Ores: chalcopyrite (copper-iron sulphide), the most common; also bornite, chalcocite, malachite and azurite. Most ores have only about 0.5 to 2 per cent copper, so the rock is crushed and concentrated by flotation, then smelted and refined by electrolysis to about 99.99 per cent purity.
- Occurrence: it forms in hydrothermal veins, in large porphyry deposits around old volcanic intrusions, and in sedimentary rocks, such as the Copperbelt of Africa.
- Uses: electrical wires and cables, transformers, motors, electronics, plumbing, roofing and coins; alloys such as brass with zinc and bronze with tin; and electric vehicles and renewable energy, since an electric car uses several times more copper than a petrol car and wind and solar plants and grids need large amounts.
- Recycling: copper can be recycled without loss of quality, and about a third of the supply comes from scrap.
Because it is central to electrification, copper is on India’s list of critical minerals and is regarded as a bellwether of economic activity, as in Tungsten, Nickel, Molybdenum and Cobalt.
Where Is Copper Found?
| Region | Details |
|---|---|
| World | Chile (the Andes, with Chuquicamata and Escondida) produces about a quarter of the world’s copper; Peru, the Democratic Republic of the Congo (the Copperbelt, shared with Zambia), China, the United States, Australia and Indonesia follow |
| Rajasthan | The Khetri–Singhana belt in Jhunjhunu district, with Khetri and Kolihan mines, a part of the Aravalli belt; also Dariba in Alwar |
| Madhya Pradesh | Malanjkhand in Balaghat district, the largest open-cast copper mine in India, started in 1982 and run by Hindustan Copper |
| Jharkhand | Singhbhum copper belt: Mosabani, Rakha, Surda and Ghatshila, mined since the nineteenth century; the Ghatshila smelter |
| Andhra Pradesh and Karnataka | Agnigundala in Guntur, and Chitradurga and Gadag in Karnataka |
| Others | Sikkim (Bhotang), Maharashtra and Gujarat have small deposits |
India’s ore has a low grade of copper, about 1 per cent or less, so domestic output has remained small, and the country imports concentrate to feed its smelters. Hindustan Copper Limited, a public sector firm, mines at Khetri, Malanjkhand and Singhbhum, and is expanding its mines underground.
What Is the Present Position of Industry and Trade?
- Smelting and refining: the large smelters are at Dahej in Gujarat (Hindalco), Mundra in Gujarat (Adani, which started a new plant in 2024), Ghatshila in Jharkhand and Khetri in Rajasthan (Hindustan Copper). The Sterlite smelter at Tuticorin in Tamil Nadu, once the largest, has been closed since 2018 after protests over pollution and court orders, which shifted India from a net exporter to an importer of refined copper in later years.
- Demand: use is growing with power grids, solar and wind power, vehicles and construction, and the country’s per-capita consumption is still low in comparison with China.
- Imports: India imports copper concentrate from Chile, Peru, Australia and others, and also scrap, and the supply risk lies in the few countries that produce it.
- Policy: exploration blocks of copper have been auctioned in recent years, and the National Critical Mineral Mission aims to raise exploration, processing and recycling, as in Mining and Quarrying.
As an analytical point, copper is where the energy transition meets resource geography: the world may need much more copper by 2040 than the known projects can supply, while India’s own resource is poor in grade, so the realistic course is a mix of overseas mine investment, efficient smelting that handles imported concentrate, and a strong recycling base, with attention to the pollution risks that closed the Tuticorin plant.

Frequently Asked Questions
What are the main uses of copper?
Copper is used in electrical wires, cables, transformers and motors because it conducts electricity very well. It is also used in electronics, plumbing, roofing, coins and alloys such as brass and bronze, and in electric vehicles and solar and wind power equipment, which makes it central to the energy transition.
Where are the major copper mines of India?
The major copper mining areas of India are the Khetri belt in Jhunjhunu district of Rajasthan, Malanjkhand in Balaghat district of Madhya Pradesh, which is the largest open-cast copper mine in the country, and the Singhbhum belt of Jharkhand, including Mosabani and Rakha.
Which is the largest copper-producing country?
Chile is the largest copper-producing country in the world and produces about a quarter of the global output, mainly from the Andes mines of Chuquicamata and Escondida. Peru, the Democratic Republic of the Congo, China, the United States and Australia are also major producers.
Which company mines copper in India?
Hindustan Copper Limited, a public sector company, is the main miner of copper ore in India, operating the Khetri and Malanjkhand mines and the Singhbhum complex. Its refining units are at Khetri in Rajasthan and Ghatshila in Jharkhand, while private firms operate smelters in Gujarat.
Why does India import copper?
India imports copper because its domestic ores are of low grade and production is small compared with demand, which is growing with electricity, vehicles and construction. India also imports concentrate for its smelters and refined copper after the Tuticorin smelter was closed in 2018.
