Hindustan Zinc Limited (HZL) is one of India's most remarkable corporate success stories — transforming from a small government enterprise in the 1960s into a global top-5 zinc producer that consistently generates among the highest profit margins in Indian industry. Headquartered in Udaipur, Rajasthan, with all its mines located across the state, HZL is the economic backbone of several Rajasthani towns and districts including Bhilwara (Gulabpura), Rajsamand (Dariba), Udaipur (Zawar, Debari), Chittorgarh (Chanderiya), and Ajmer (Kayad). This comprehensive guide covers everything about Hindustan Zinc Limited — its history, operations, mines, financials, and massive impact on Rajasthan.
Hindustan Zinc was established in 1966 by the Government of India to develop and produce zinc from the newly discovered ore deposits in Rajasthan. The first operations began at the Zawar mines near Udaipur — a site with ancient mining history dating back over 2,500 years (Zawar is believed to be the world's earliest zinc smelting site). Through the 1970s and 1980s, HZL expanded its operations, discovering the massive Rampura Agucha deposit in 1977. In 2002, the Government of India privatized HZL by selling 26% to Sterlite Industries and subsequently divesting more stake, eventually resulting in the Vedanta Group (through Vedanta Limited) controlling approximately 64.9% of the company.
The economic and social impact of Hindustan Zinc on Rajasthan is profound and multi-dimensional. HZL is one of the largest taxpayers in Rajasthan, contributing thousands of crores annually in state and central taxes, royalties, and levies. The company's direct and indirect employment supports livelihoods for over 1 lakh families across multiple districts. HZL's CSR programs — operating under the brand "Hindustan Zinc Saksham" — have reached over 1 million beneficiaries through education, healthcare, water, livelihood, and sustainable development programs. The company has invested significantly in building roads, schools, hospitals, and community infrastructure in mining-adjacent communities — transforming rural Rajasthan in very real ways.
Hindustan Zinc Limited is a crown jewel in the Vedanta Group — the diversified natural resources conglomerate founded by billionaire Anil Agarwal. Vedanta Limited (BSE: 500295, NSE: VEDL), listed on Indian exchanges, holds majority control of HZL. Vedanta Limited is itself majority-owned by Vedanta Resources Plc, a London-headquartered company. HZL contributes a major share of Vedanta Limited's overall profits and is the primary driver of Vedanta's dividend income, which in turn is used to service the holding company's debt structure. This makes HZL critically important not just for Rajasthan but for the entire Vedanta Group's financial health.
