Rajasthan Test 8

Rajasthan's mineral wealth is among the most extensive and diverse of any Indian state, and the mining and quarrying sector makes a significant contribution to the state's economic output, revenue, and employment. The state is India's leading producer of several important minerals and rock materials and has a strong tradition of extractive industries. The marble quarrying industry centred on Makrana in Nagaur district has an ancient history and global reputation. Makrana marble, a pure white crystalline limestone of exceptional quality, was used in the construction of the Taj Mahal, the Victoria Memorial in Kolkata, and countless temples and palaces across the subcontinent. The stone remains in high demand for premium construction, sculpture, and decorative applications both domestically and in export markets. The mines at Makrana employ thousands of workers and support a network of cutting, polishing, and trading enterprises in the region. Rajasthan is the largest producer of granite in India, with extensive granite deposits distributed across the southern and eastern districts of the state. Rajasthan granites come in a remarkable range of colours and textures including the distinctive pink granite of Jalore, black granite from various locations, and multicoloured varieties that have found strong demand in domestic construction and export markets, particularly in Gulf countries and European markets. Granite processing units that cut, polish, and finish granite blocks for flooring, cladding, counter tops, and monumental applications are concentrated in clusters around the major quarrying areas. Rajasthan accounts for a disproportionately large share of India's non-metallic mineral production, including limestone, dolomite, silica sand, feldspar, calcite, mica, and gypsum. These minerals feed cement plants, glass factories, ceramic tile manufacturers, and chemical industries both within Rajasthan and across India. The state has some of India's largest limestone deposits, which have supported the establishment of major cement manufacturing plants in districts including Chittorgarh, Udaipur, Nagaur, and Jodhpur. The zinc and lead mining complex at Zawar in Udaipur district, operated by Hindustan Zinc Limited, is one of the world's largest integrated zinc-lead mining and smelting operations. Hindustan Zinc, which is a subsidiary of Vedanta Resources, produces a significant share of India's zinc and lead output and is a major exporter. The company operates multiple underground mines and has been deepening its operations as surface and near-surface ore bodies are progressively exhausted. The Rampura Agucha mine in Bhilwara district, also operated by Hindustan Zinc, has at various times been considered the world's largest open-pit zinc mine in terms of ore grade and production. The oil and gas sector has an important presence in Rajasthan, particularly through the Cairn India operated Mangala oil field in the Barmer-Sanchore Basin. The Mangala field, which began production in 2009, has at its peak been one of India's largest onshore oil producing fields, contributing significantly to domestic crude oil production. Production from Rajasthan's oil fields has declined from its peak levels as the fields mature, but ongoing exploration and enhanced oil recovery programmes aim to maximise recovery from known reserves. The state government levies royalties on mineral extraction, which constitute an important source of revenue, and the state has been working to strengthen the regulatory and enforcement framework around mining to prevent illegal extraction and ensure that environmental obligations are met by mine operators. The Rajasthan Minor Mineral Concession Rules and the Rajasthan Major Mineral Concession Rules govern the grant and regulation of mining leases. Environmental and social challenges associated with mining including dust pollution, groundwater depletion, displacement of communities, and land degradation require effective regulatory oversight and industry adherence to environmental management plans. Rajasthan has been working to develop a comprehensive mineral policy that balances the imperatives of revenue generation, employment creation, and industrial supply with environmental sustainability and the rights of local communities.
