Major Copper and Zinc Producing States and Mines in India

India holds strategic reserves of non-ferrous base metals like copper and zinc, which are essential for electrical equipment, construction, and metallurgical industries. Copper and zinc occurrences are concentrated in Precambrian rock formations across Rajasthan, Madhya Pradesh, Jharkhand, Andhra Pradesh, and Maharashtra. Domestic production is managed by state-run enterprises and major private mining corporations operating large-scale underground and open-cast extraction units.

Copper Resources and Major Mines in India

Copper is a vital non-ferrous metal characterized by high electrical conductivity, ductility, and corrosion resistance. Major Indian copper reserves are found along folded shear zones within ancient metamorphic terrains.

Madhya Pradesh

• Madhya Pradesh is the largest copper-producing state in India, contributing more than half of the country’s total mine output.
• The Malanjkhand Copper Belt in Balaghat district contains a large open-cast mine operated by Hindustan Copper Limited (HCL).
• Malanjkhand deposits occur as a granitic pluton intruded with quartz-copper sulfide veins.
• Key ore minerals include chalcopyrite, pyrite, and secondary chalcocite.

Rajasthan

• Rajasthan holds the largest total estimated reserves of copper ore in India.
• The Khetri Copper Belt extends along the Aravalli range through Jhunjhunu and Sikar districts.
• Prominent underground mines in the Khetri belt include Madhan-Kudhan, Kolihan, and Chandmari.
• The Kho-Dariba area in Alwar district and the Delwara-Kerovli area in Udaipur district host additional copper ore bodies.

Jharkhand

• The Singhbhum Copper Belt extends in an arc shape through East Singhbhum, West Singhbhum, and Saraikela-Kharsawan districts.
• Mosabani, Rakha, Surda, and Kendadih are historical copper-mining centres located along the Singhbhum Shear Zone.
• The copper mineralization occurs in Proterozoic schists, quartzites, and phyllites.
• These ores frequently associate with uranium and apatite-magnetite deposits.

Other Copper Bearing States

• Andhra Pradesh: Guntur and Prakasam districts host the Agnigundala copper-lead belt with key workings at Bandalamottu and Nallakonda.
• Karnataka: Chitradurga and Hassan districts contain smaller copper veins worked at Kalyadi and Ingaldhal.
• Maharashtra: Thanewasna in Chandrapur district and Pular-Parsori in Nagpur district hold copper sulfide occurrences.

Zinc Resources and Major Mines in India

Zinc is a primary non-ferrous metal used predominantly for galvanizing steel to prevent rusting, as well as in die-casting alloys and chemical manufacturing.

Rajasthan

• Rajasthan maintains an absolute domestic monopoly in zinc and lead mining, accounting for practically all of India’s primary zinc ore extraction.
• Hindustan Zinc Limited (HZL) operates the primary zinc and lead production centres across the state.
• The Rampura Agucha mine in Bhilwara district is one of the world’s largest zinc-lead deposits, operating as an advanced underground mine after initial open-pit extraction.
• The Zawar mineral belt in Udaipur district is a historic multi-mine complex comprising the Mochia, Balaria, Zawar Mala, and Baroi mines.
• The Sindesar Khurd and Rajpura-Dariba mines in Rajsamand district contain rich silver-bearing zinc-lead sulfide ore bodies.
• The Kayad mine in Ajmer district extracts high-grade zinc-lead ore from underground workings.

Minor Zinc Occurrences in Other States

• Andhra Pradesh: Bandalamottu deposit in Guntur district contains lead-zinc veins.
• Gujarat: Ambaji area in Banaskantha district holds multi-metal lead-zinc-copper deposits.
• Odisha: Sargipalli deposit in Sundargarh district contains lead-zinc mineralization.
• Sikkim: Bhotang and Pacheykhani mines in Rangpo hold complex polymetallic copper-zinc-lead deposits.

Industrial Processing and Smelting Facilities

Extracted sulfide ores undergo mineral beneficiation, concentration by froth flotation, and thermal roasting before electrolytic refining.

Copper Smelters and Refineries

• Hindustan Copper Limited operates integrated copper complexes at Khetri (Rajasthan) and Ghatsila (Jharkhand).
• Hindalco Industries (Aditya Birla Group) runs a large custom copper smelting and refining plant at Dahej in Gujarat.
• Vedanta Limited operates a custom copper smelter at Tuticorin (Thoothukudi) in Tamil Nadu.
• Reliance Industries developed a large copper processing plant at Mundra in Gujarat.

Zinc Smelters and Refineries

• Hindustan Zinc Limited runs hydrometallurgical zinc smelters at Chanderiya (Chittorgarh) and Dariba (Rajsamand) in Rajasthan.
• The Debari zinc smelter near Udaipur operates an electrolytic refining unit.
• HZL also operates a zinc ingot casting and refining facility at Haridwar in Uttarakhand.

Facts on Indian Copper and Zinc Mining

• Sphalerite, also known as zinc blende, is the chief ore mineral of zinc mined throughout Rajasthan.
• Chalcopyrite is the most abundant copper ore mineral in India, containing roughly 34.5 percent pure copper by weight.
• Malanjkhand in Madhya Pradesh holds the single largest contiguous open-pit copper ore mine in Asia.
• The ancient Zawar mines in Rajasthan contain the earliest direct archaeological evidence of zinc smelting by distillation dating back over two millennia.
• Hindustan Copper Limited is the only vertically integrated public sector company in India that mines copper ore and processes it into refined metal.
• Rampura Agucha in Bhilwara district has an exceptionally high average combined lead-zinc ore grade exceeding 12 percent.
• Secondary recovery of pure silver occurs at the Dariba and Chanderiya smelters during the refining of lead-zinc concentrates.
• India relies on large-scale imports of unrefined copper concentrates from South America and Australia to feed its domestic coastal smelters.
• The Indian Bureau of Mines (IBM), headquartered in Nagpur, maintains the official national inventory of mineral resources and reserves.
• Zinc is used alongside copper to produce brass, one of the oldest and most common engineering alloys.
