Introduction

This is Rajasthan's mineral story in miniature: ancient wealth, modern scale, and a set of questions about who benefits, at what ecological cost, and with what vision for the future, that are as urgent today as they were when the first Zawar smelter was lit two and a half millennia ago. Rajasthan is India's most mineral-rich state, contributing approximately 22 percent of the nation's total mineral production by value. Its geological canvas, spanning the ancient Aravalli system, the Vindhyan sedimentary formations, the Marwar Supergroup, and the Great Indian Desert's subsurface, contains over 79 varieties of minerals, of which 57 are commercially exploited. No other Indian state offers such diversity of mineral endowment across such a large and geologically complex territory.

ALTERNATIVE OPENING 1 — QUOTE-BASED KAUTILYA WROTE IN THE ARTHASHASTRA IN THE 4TH CENTURY BCE THAT THE KING WHO CONTROLS THE MINES CONTROLS THE KINGDOM. THE MAURYAN EMPIRE'S ATTENTION TO MINERAL RESOURCES WAS NOT INCIDENTAL. IT WAS FOUNDATIONAL. RAJASTHAN, WHICH SITS ON SOME OF THE OLDEST AND MOST MINERAL-RICH GEOLOGICAL FORMATIONS ON EARTH, HAS KNOWN THIS TRUTH FOR MILLENNIA. EVERY GREAT POWER THAT SOUGHT TO CONTROL THE INDIAN SUBCONTINENT, THE MAURYAS, THE MUGHALS, THE MARATHAS, THE BRITISH, UNDERSTOOD THAT RAJASTHAN'S MOUNTAINS WERE NOT MERELY SCENIC. THEY WERE STRATEGIC. Alternative Opening 2 — Book-Based In The New Map (2020), energy historian Daniel Yergin argues that the 21st century's great power competition will not be fought primarily over oil. It will be fought over critical minerals: zinc, lead, copper, lithium, rare earths, and the dozens of other elements that the green energy transition, the semiconductor revolution, and advanced manufacturing demand. Rajasthan, which holds India's largest reserves of zinc, lead, rock phosphate, gypsum, wollastonite, and feldspar, sits at the centre of exactly this strategic competition. The desert state is not merely historically mineral-rich. It is strategically mineral-essential for India's 21st-century ambitions.

ALTERNATIVE OPENING 3 — ANECDOTE-BASED IN 2022, THE GEOLOGICAL SURVEY OF INDIA (GSI) COMPLETED A DETAILED SURVEY OF THE SALUMBER BLOCK IN UDAIPUR DISTRICT AND ANNOUNCED THE DISCOVERY OF A SIGNIFICANT COPPER DEPOSIT ESTIMATED AT OVER 5.9 MILLION TONNES OF ORE. THE ANNOUNCEMENT WAS MADE QUIETLY IN A TECHNICAL BULLETIN. BUT ITS IMPLICATIONS WERE SIGNIFICANT: INDIA IMPORTS OVER 90 PERCENT OF ITS COPPER NEEDS. A DOMESTIC DISCOVERY OF THIS SCALE IN A STATE ALREADY PRODUCING 79 MINERAL VARIETIES REPRESENTED EXACTLY THE KIND OF GEOLOGICAL INTELLIGENCE THAT THE NATIONAL MINERAL EXPLORATION POLICY (2016) HAD BEEN DESIGNED TO GENERATE. RAJASTHAN'S MINERAL STORY IS NOT CONCLUDED. IT IS STILL BEING WRITTEN, ONE GSI SURVEY AT A TIME. THESIS Rajasthan's mineral wealth is the product of geological time measured in billions of years, spread across three major geological formations, and encompassing metallic minerals, non-metallic industrial minerals, building stones, and fuel minerals of national and international significance. But mineral wealth is not simply a geological fact. It is a governance challenge, an ecological responsibility, a social contract with mining communities, and an economic opportunity that must be managed across time horizons longer than any single government's tenure. This essay examines Rajasthan's mineral wealth through five dimensions: its geological foundations and mineral inventory, its metallic and industrial mineral sectors, its stone and construction mineral economy, the ecological and social dimensions of mining, and the governance and future trajectory of the sector.

Dimension 1

The Aravalli Supergroup, among the world's oldest geological formations at approximately 2.5 to 3.5 billion years old, forms the mineralogical backbone of Rajasthan. The Aravallis are a Precambrian metamorphic complex: ancient sedimentary and volcanic rocks that have been subjected to intense heat and pressure over geological time, concentrating metallic minerals into economically exploitable ore bodies. The zinc-lead deposits of Zawar, Rampura-Agucha, and Rajpura-Dariba in Udaipur and Bhilwara districts are products of this Aravalli mineralisation. The copper deposits of the Khetri Copper Belt in Jhunjhunu district are similarly hosted in Aravalli-age rocks. The emerald deposits of Rajgarh in Ajmer district, among the few emerald occurrences in Asia outside Colombia, are pegmatite deposits associated with Aravalli metamorphism.

The Vindhyan Supergroup, younger at approximately 1.7 billion years, comprises vast sedimentary sequences of sandstone, limestone, and shale that underlie large parts of southeastern and eastern Rajasthan. The famous Dholpur sandstone and Karauli sandstone, the red and pink building stones that gave New Delhi's Parliament House and thousands of Rajasthani forts their distinctive colour, are Vindhyan formations. The limestone deposits of Chittorgarh, Bundi, Kota, and Nagaur districts, the raw material for Rajasthan's dominant cement industry, are Vindhyan sedimentary rocks.

The Marwar Supergroup of western Rajasthan, predominantly Cambrian-age limestones, sandstones, and evaporite deposits, hosts the state's vast gypsum reserves in Nagaur and Bikaner districts, its rock salt deposits in Sambhar and Pachpadra, and the petroleum and natural gas reserves of Barmer district, whose Cairn-ONGC Mangala field is India's largest onshore oil producer.

Rajasthan's mineral diversity is thus a function of this three-formation geological architecture. The Aravallis provide the metallic minerals. The Vindhyans provide the building stones and limestone. The Marwar Supergroup provides the industrial minerals and energy resources. Together, they make Rajasthan's subsurface one of the most richly endowed in Asia.

DIMENSION II: METALLIC MINERALS — ZINC, LEAD, COPPER, AND THE GLOBAL SUPPLY CHAIN

Rajasthan's metallic mineral sector is dominated by three commodities that have global significance: zinc, lead, and copper. Together, they account for the largest share of the state's mineral revenue and position Rajasthan at the centre of India's critical mineral strategy.

Zinc and Lead at Zawar, Rampura-Agucha, and Rajpura-Dariba are the centrepiece of Rajasthan's metallic mineral economy. Hindustan Zinc Limited (HZL), operating the world's second-largest zinc mine complex from its Rajasthan operations, produced approximately 1.08 million tonnes of mined metal in 2022-23, making India one of the world's top five zinc producers. The Rampura-Agucha mine in Bhilwara district is the world's largest open-pit zinc-lead mine by ore grade, with zinc content of approximately 14.5 percent, exceptional by global standards where grades of 5 to 8 percent are typical. HZL's integrated smelting operations at Chanderiya near Chittorgarh and Dariba in Rajsamand process Rajasthan ore into refined zinc, lead, and silver, with silver recovery alone contributing over Rs 2,000 crore annually to revenue. Rajasthan accounts for over 90 percent of India's zinc production and approximately 75 percent of its lead production.

The Khetri Copper Belt in Jhunjhunu district is the most significant copper mineralisation in Rajasthan, hosting the Khetri, Kolihan, and Chandmari mines operated historically by Hindustan Copper Limited (HCL). Khetri's copper was so significant in the pre-Independence period that the town was called the "Copper City of Rajasthan". Reference has declined in recent decades due to ore depletion in easily accessible zones and infrastructure constraints, but ongoing exploration in the Khetri belt continues to identify new ore bodies. The new copper discovery at Salumber in Udaipur (2022) and the Bhagaliya copper deposit in Sikar represent the next generation of Rajasthan copper development.

Silver deserves separate mention. Rajasthan is India's largest silver producer, with HZL's Rajasthan operations producing approximately 700 tonnes of silver annually, making India the world's twelfth largest silver producer. Silver's dual role as a precious metal and an industrial input for solar panels, electronics, and medical devices gives Rajasthan's silver production strategic significance beyond its monetary value. As the global solar energy transition accelerates, demand for silver in photovoltaic cells is projected to rise sharply, making Rajasthan's silver output increasingly strategic.

Iron ore deposits in the Bhilwara, Jaipur, and Jhunjhunu belts are smaller than those of Odisha or Jharkhand but significant for regional steel production. The manganese deposits of Banswara and tungsten occurrences at Degana in Nagaur add to the state's metallic mineral portfolio. Rajasthan's wollastonite deposits, primarily in the Sirohi and Dungarpur districts, are among the largest in Asia and are entirely non-substitutable for certain ceramic, paint, and metallurgical applications. India controls approximately one-third of global wollastonite reserves, and Rajasthan hosts the majority of India's share.

DIMENSION III: INDUSTRIAL AND CONSTRUCTION MINERALS — THE INVISIBLE BACKBONE

The category of minerals that rarely appears in political speeches or economic headlines but quietly underpins every road, every building, every fertilised field, and every industrial process in India is what geologists call industrial minerals. Rajasthan is India's dominant supplier of several of the most important.

Rock Phosphate from the Jhamarkotra mines near Udaipur is perhaps the most strategically significant of Rajasthan's non-metallic mineral resources. Rock phosphate is the raw material from which phosphatic fertilisers are manufactured. India imports approximately 85 percent of its rock phosphate requirements from Morocco, Jordan, and China. Rajasthan's Jhamarkotra deposit, operated by RSMML (Rajasthan State Mines and Minerals Limited), holds reserves estimated at over 260 million tonnes and is one of the largest rock phosphate deposits in Asia outside North Africa. Fully developing Jhamarkotra would reduce India's fertiliser import dependence, directly strengthening food security and agricultural self-reliance. India's import bill for phosphatic raw materials exceeded Rs 18,000 crore in 2022-23. Every tonne mined at Jhamarkotra reduces that outflow.

Gypsum from Nagaur, Barmer, Bikaner, and Jaisalmer districts is another mineral of exceptional agricultural importance. Gypsum is applied to fields to improve soil structure, reduce soil salinity, and provide calcium and sulphur for crop nutrition. Rajasthan holds approximately 80 percent of India's gypsum reserves, estimated at over 1,000 million tonnes. RSMML's Nagaur gypsum operations supply farmers across Rajasthan, Punjab, Haryana, and Gujarat. As India's soils face increasing salinity stress from decades of irrigation without drainage, gypsum's role in agricultural productivity will only grow.

Limestone from the Vindhyan and Aravalli formations feeds Rajasthan's dominant cement industry. Rajasthan is the largest cement-producing state in India, contributing approximately 15 percent of national cement output. The major cement clusters in Chittorgarh, Bundi, Sirohi, and Nagaur are built on locally mined limestone. Major producers including Ultratech, ACC, Shree Cement, JK Cement, and Mangalam Cement have concentrated in Rajasthan precisely because of the quality and abundance of its limestone. Shree Cement, founded in Rajasthan in 1979, has grown into one of Asia's most efficient cement producers primarily by leveraging Rajasthan's limestone quality and energy cost advantages.

Rajasthan's building stones are its most visually iconic mineral product. The pink sandstone of Dholpur built the New Parliament House, the North and South Blocks of the Central Secretariat, and Rashtrapati Bhavan in New Delhi. The Jodhpur blue stone (Jodhpuri sandstone) has been exported to Europe, the Middle East, and the Americas as a premium paving and cladding material. Makrana marble, quarried from the Aravalli formation near Nagaur, is the stone from which the Taj Mahal was built. Makrana marble's distinctive pure white crystalline structure, produced by the same ancient metamorphic processes that created the Aravalli mineral belt, is geologically unique. India exports Rajasthan's dimension stones to over 140 countries, generating foreign exchange of approximately Rs 3,500 crore annually.

Feldspar and mica from the Ajmer, Bhilwara, and Tonk districts feed India's ceramics, glass, and electronics industries. Rajasthan produces approximately 60 percent of India's feldspar output. Bentonite and Fuller's Earth from Barmer and Bikaner are industrial minerals used in drilling fluids, foundry casting, and pharmaceutical applications. The salt from Sambhar Lake in Jaipur district, the largest inland saltwater lake in India, has been harvested since before recorded history and supplies approximately 8 percent of India's salt production.

DIMENSION IV: ECOLOGY, COMMUNITY, AND THE SOCIAL COST OF MINING

Sunita Narain of the Centre for Science and Environment has argued that mining in India is consistently characterised by a fundamental injustice: those who bear the costs of mining are rarely those who receive its benefits. In Rajasthan, this injustice takes multiple specific forms.

The Aravalli range is the ecological spine of northwestern India. Its forests recharge the groundwater of Delhi, Haryana, and Rajasthan. Its hills break the advance of the Thar Desert. Its biodiversity includes critically endangered species. And it is also Rajasthan's most intensively mined geological zone. The Supreme Court of India's landmark judgement in MC Mehta v. Union of India (2002), the Aravalli mining case, banned mining across large sections of the Aravalli range in Haryana and Rajasthan, recognising that the ecological services provided by the intact mountain system exceeded the economic value of the minerals being extracted. The judgement's implementation has been contested, partial, and repeatedly circumvented, reflecting the tension between short-term extraction value and long-term ecological function.

Dust pollution from mining and stone-cutting operations is a public health emergency in Rajasthan's mining districts. Silicosis, the irreversible lung disease caused by inhaling silica dust, is endemic among the stone cutters, quarry workers, and miners of Jodhpur, Barmer, Karauli, and Bhilwara. A 2019 study by the Rajasthan government's Labour Department estimated that over 1.5 lakh workers in the sandstone and marble cutting industry were at high risk of silicosis. The National Green Tribunal (NGT) has repeatedly directed Rajasthan to enforce dust suppression measures, provide protective equipment, and establish health screening programmes for mining workers. Implementation remains inconsistent.

Tribal communities in the mineral-rich districts of Dungarpur, Banswara, Udaipur, and Pratapgarh, which overlay some of Rajasthan's most significant mineral deposits, have historically been displaced from their lands and excluded from the prosperity generated by extraction from beneath their feet. The Mines and Minerals (Development and Regulation) Amendment Act (2015) introduced the District Mineral Foundation (DMF) and the Pradhan Mantri Khanij Kshetra Kalyan Yojana (PMKKKY), which require mining companies to contribute a percentage of royalty payments into a district-level fund for the welfare of mining-affected communities. Rajasthan's DMFs have collected over Rs 3,500 crore since 2015, but community oversight of fund utilisation and actual delivery of welfare programmes to affected villages remain areas requiring stronger institutional attention.

Illegal mining is a pervasive governance failure across Rajasthan's minor minerals sector. Sand, gravel, and stone quarried without leases from riverbeds and hillsides cause direct ecological damage, deprive the state exchequer of revenue, and undermine legal operators who bear compliance costs. The Rajasthan Minor Mineral Concession Rules (2017) and the e-Ravi (electronic Rajasthan Mines Vigilance Intelligence) system have improved monitoring. But the scale of illegal minor mineral extraction, estimated at several times the volume of legal extraction in some districts, requires enforcement capacity that the state's mining department currently lacks.

DIMENSION V: GOVERNANCE, POLICY, AND THE FUTURE OF RAJASTHAN'S MINERAL ECONOMY

RSMML (Rajasthan State Mines and Minerals Limited), established in 1979, is the primary state agency for mineral development and the largest producer of rock phosphate, gypsum, limestone, and lignite in the state. It operates the Jhamarkotra rock phosphate complex, the Nagaur gypsum mines, the Dholpur sandstone quarries, and the Kansili lime complex among others. RSMML's revenue of approximately Rs 1,200 crore in 2022-23 makes it one of Rajasthan's largest public enterprises, but its production levels are well below the geological potential of the deposits it manages.

The Rajasthan Mineral Policy 2015, updated as the Rajasthan Mineral Policy 2022, is the current governance framework. Its stated objectives include maximising mineral revenue while ensuring environmental sustainability, tribal welfare, and value addition within the state. The policy's key innovations include block-level mineral auctions to replace the discretionary lease allocation system that had generated significant corruption, mandatory value addition requirements that incentivise processing over raw export, and green mining standards adapted from the Indian Bureau of Mines (IBM) framework.

Critical minerals are the most strategically significant dimension of Rajasthan's mineral future. The Ministry of Mines' Critical Minerals List (2023) identifies 30 minerals essential for clean energy, defence, and advanced technology manufacturing. Rajasthan's geology contains significant occurrences of several: copper (essential for EVs and renewable energy), cobalt traces in Khetri belt, lithium indications in Barmer district's Palaeocene sediments (under exploration), rare earth element occurrences in Aravalli pegmatites, and graphite deposits in Ajmer and Bhilwara. India's National Critical Minerals Mission (2024), with Rs 34,000 crore allocated, specifically targets accelerated exploration in these categories. Rajasthan's GSI circles have been assigned expanded exploration mandates for critical minerals in the Aravalli belt.

Rajasthan's petroleum and natural gas sector, centred on the Barmer-Sanchore basin, deserves separate recognition. The Mangala, Bhagyam, and Aishwariya fields operated by Cairn India (now Vedanta) and ONGC produce approximately 1.5 lakh barrels of oil per day, making Rajasthan the largest onshore oil-producing state in India. The Barmer Refinery of HPCL-Rajasthan Refinery Limited, under construction at Pachpadra with an investment of Rs 43,129 crore, will process Rajasthan crude into refined petroleum products when commissioned, marking a shift from raw material export to value-added production within the state.

Technology and digitisation are transforming Rajasthan's mineral governance. The Rajasthan Mines and Geology Department's e-Ravi portal provides real-time monitoring of mining leases, production data, and royalty payments. Drone-based survey systems are being deployed for volumetric assessment of quarry production to reduce royalty evasion. The National Mineral Exploration Trust (NMET) is funding geophysical surveys of under-explored blocks in western Rajasthan's Marwar Supergroup, where the subsurface geology remains only partially characterised.

Penultimate Analysis

Rajasthan's mineral wealth is a one-time geological inheritance. The choices made in the next two decades about how it is extracted, processed, governed, and whose welfare it serves will determine whether it becomes the foundation of lasting prosperity or the source of lasting ecological debt. Five priorities must guide this stewardship. First, accelerate value addition and downstream processing. Rajasthan currently exports the majority of its mineral production as raw or semi-processed material. Zinc concentrate goes to smelters, sandstone goes to cutting units in other states, rock phosphate goes to fertiliser plants in Gujarat and Andhra Pradesh. Every stage of processing that happens outside Rajasthan is a job, a tax, and a multiplier that the state loses. Mineral Special Economic Zones anchored around the Zawar-Chanderiya zinc complex, the Jhamarkotra phosphate complex, and the Makrana marble belt would create the infrastructure for integrated mineral value chains within the state.

Second, fully operationalise District Mineral Foundations as genuine community development institutions. Rajasthan's DMFs have collected Rs 3,500 crore but community oversight remains weak and fund utilisation uneven. Gram Sabha-level committees with mandatory representation of mining-affected women and tribal communities should have approval authority over DMF project selection. Annual social audits of DMF expenditure, modelled on MGNREGA's social audit framework, would ensure that the communities bearing mining's costs also govern its compensation.

Third, build Rajasthan's critical minerals exploration and processing capacity as a strategic priority. The state should establish a Rajasthan Critical Minerals Corporation as a joint venture between RSMML, the national critical minerals mission, and private sector partners, specifically focused on accelerated exploration and pilot processing of cobalt, lithium, rare earth elements, and graphite in the Aravalli and Barmer belts. India's dependence on China for critical mineral processing is a strategic vulnerability. Rajasthan's geology offers the foundation for a domestic alternative.

Fourth, enforce green mining standards with credible consequences. The Rajasthan Green Mining Mission, proposed under the state's environmental policy, must translate into mine-level environmental management plans with verifiable milestones, enforceable penalties, and mandatory mine closure funds. The Aravalli Ecological Protection Zone notified by the Supreme Court must be maintained with zero tolerance for encroachment by mining activity, and the state's forest cover target of 20 percent under Viksit Rajasthan 2047 must incorporate explicit provisions for post-mining land rehabilitation.

Fifth, invest in the health of mining communities as a non-negotiable obligation. The silicosis crisis among Rajasthan's stone cutters is a slow-motion public health emergency that the state has known about for decades without adequate response. Universal occupational health screening for all registered mine workers, wet drilling and enclosed cutting standards in all sandstone and marble operations, and compensation and rehabilitation programmes for silicosis-affected workers and their families must be funded through the DMF mechanism and audited by the National Human Rights Commission.

Conclusion

The Zawar mines have been burning zinc for 2,500 years. The Makrana quarries have been cutting marble since before the Mughal Empire. The Jhamarkotra phosphate deposits have been feeding Indian agriculture since Independence. The Barmer oilfields have been powering Indian refineries since 2009. Rajasthan's mineral wealth is not a recent discovery. It is a civilisational inheritance, accumulated over geological time, extracted across human time, and now reaching a moment of decision about whether the next generation of extraction will be wiser, more just, and more enduring than what preceded it. Five dimensions of this essay have illuminated five dimensions of that inheritance. The geological foundation of three ancient formations containing the most diverse mineral inventory of any Indian state. The metallic mineral sector that makes Rajasthan the zinc and silver capital of India and positions it at the centre of the nation's critical mineral strategy. The industrial and construction minerals that feed India's agriculture, cement its infrastructure, and stone its most celebrated monuments. The ecological and social costs that must be acknowledged, compensated, and reduced if mineral wealth is to be genuinely shared. And the governance architecture that determines whether extraction generates lasting prosperity or lasting damage.

Kautilya was right that the nation controlling the mines controls the kingdom. But he wrote in an era before ecological science, before constitutional rights, and before the knowledge that some resources, once depleted, do not return. The 21st-century revision of his insight is this: the nation that mines wisely, distributes justly, adds value domestically, and rehabilitates what it disturbs is the nation that earns the right to its mineral inheritance across generations.

Rajasthan has the geological endowment. It has the institutional framework. It has the human capital in its mining communities, its engineering colleges, and its geological survey tradition. What it requires now is the political will to treat its mineral wealth not as a budget line to be maximised in the current fiscal year but as a civilisational asset to be stewarded across the coming century.

The Aravallis took three billion years to make what they hold. The least this generation can do is take twenty years to extract it with care.
