At Zawar, near Udaipur, archaeologists have found evidence of zinc smelting going back well over a thousand years — India was among the first places in the world to produce metallic zinc. Today, the same region is at the heart of India's zinc industry. Rajasthan's ancient rocks, especially in the Aravallis, hold an extraordinary variety of minerals, earning the state the nickname "museum of minerals". For RAS, minerals combine geography (where), economy (production and revenue) and environment (the costs of mining).
Why Rajasthan is rich in minerals
The Aravallis and associated rock formations are among the oldest in India. Over billions of years, geological processes concentrated metals and non-metallic minerals in these rocks. The desert basins of the west hold lignite, gypsum and petroleum.
Metallic minerals
| Mineral | Main areas | Notes |
|---|---|---|
| Lead and zinc | Zawar (Udaipur), Rampura-Agucha (Bhilwara), Rajpura-Dariba (Rajsamand), Sindesar Khurd | Rajasthan produces nearly all of India's lead and zinc; Rampura-Agucha is among the world's largest zinc mines; smelters at Chanderiya (Chittorgarh) and Debari (Udaipur) |
| Copper | Khetri–Kolihan belt (Jhunjhunu), Kho-Dariba (Alwar) | Hindustan Copper's Khetri complex |
| Silver | By-product of lead-zinc ores | Rajasthan is India's largest silver producer |
| Tungsten | Degana (Nagaur) | One of India's few tungsten deposits |
| Iron ore | Morija (Jaipur), Nimla, Dabla | Small deposits |
| Manganese | Banswara | Small deposits |
Non-metallic minerals
| Mineral | Main areas | Notes |
|---|---|---|
| Rock phosphate | Jhamarkotra (Udaipur), Birmania (Jaisalmer) | Fertiliser raw material; Rajasthan is a leading producer |
| Gypsum | Bikaner, Nagaur, Hanumangarh, Barmer, Jaisalmer | Rajasthan produces the large majority of India's gypsum; used for cement, fertiliser and reclaiming alkaline soils |
| Wollastonite | Sirohi, Dungarpur | Rajasthan is almost the sole producer in India |
| Marble | Makrana (Didwana-Kuchaman), Rajsamand, Udaipur, Banswara (green marble), Jaisalmer (yellow) | Makrana's white marble was used in the Taj Mahal |
| Limestone | Chittorgarh, Jaisalmer, Nagaur, Sirohi, Kota (Kota stone) | Cement industry — large cement plants at Chittorgarh, Nimbahera, Beawar and elsewhere |
| Sandstone | Dholpur, Karauli, Bharatpur, Kota, Jodhpur | Red sandstone of Dholpur used in Delhi's buildings |
| Granite | Jalore, Barmer, Sirohi | Jalore is a granite hub |
| Mica | Bhilwara, Ajmer | Declined in importance |
| Feldspar, quartz, soapstone, fluorite, asbestos, ball clay, fuller's earth | Various | Industrial minerals |
Fuel minerals
| Mineral | Areas | Notes |
|---|---|---|
| Lignite | Barmer, Bikaner (Palana, Barsingsar), Nagaur | Used in thermal power plants |
| Petroleum | Barmer basin — Mangala, Bhagyam, Aishwariya and other fields | Discovered in the early 2000s by Cairn; one of India's most important onshore oil fields; a refinery-cum-petrochemical complex is being built at Pachpadra (Balotra) |
| Natural gas | Jaisalmer basin (Manihari Tibba, Tanot) | Used for power generation |
Economic importance
- Minerals are a major source of state revenue (royalties) and employment.
- They support industries: cement, zinc and lead smelting, marble and granite processing, fertilisers, ceramics and glass.
- The Rajasthan Mineral Policy (the state has issued successive policies) aims to promote exploration, value addition, transparency (auction of mines) and environmental safeguards.
- A District Mineral Foundation in each mining district uses a share of mining revenue for local development.
Issues in mining
| Issue | Explanation |
|---|---|
| Illegal mining | Especially of sandstone, marble and sand; loss of revenue and environmental damage |
| Environmental damage | Destruction of Aravalli hills, deforestation, dust, groundwater depletion |
| Silicosis | A serious lung disease among sandstone and stone-quarry workers; Rajasthan introduced a silicosis policy (2019) providing compensation and rehabilitation |
| Displacement | Loss of land and livelihoods for local communities |
| Worker safety | Informal, unsafe working conditions |
Practice
Prelims-style:
- Why is Rajasthan called a "museum of minerals"?
- Where are the main zinc mines of Rajasthan?
- Where is tungsten found in Rajasthan?
- Which mineral is Rajasthan almost the sole producer of in India?
- Which oil fields are in the Barmer basin?
Mains-style (50 words): What is silicosis, and why is it a concern in Rajasthan?
Mains-style (100 words): Discuss the economic importance of minerals in Rajasthan and the challenges of sustainable mining.
