Hindustan Zinc Limited has approved the construction of a zinc tailings reprocessing plant at Rampura Agucha in Bhilwara district, Rajasthan. The project involves an investment of up to INR 38.23 billion and is designed with a capacity of 10 million tonnes per annum (MTPA). The facility is scheduled for completion within 28 months.
The plant will extract zinc, silver and other metals from processed tailings, which are the fine residues left after mineral extraction and are generally considered as a waste product. The project forms part of the company’s broader plan to double production capacity.
“We are proud to launch India’s first tailings reprocessing plant at Rampura Agucha, developed in partnership with global experts. This facility enables us to reprocess historical waste and store it responsibly, in line with high environmental standards. It strengthens our unique value proposition and supports our ambitious 2x growth vision while advancing our broader sustainability commitments. Modern tailing operations also create opportunities to innovate and recover a broader range of metals that are important for technological progress and the energy transition,” said Arun Misra, Chief Executive Officer of Hindustan Zinc.
Earlier this year, Hindustan Zinc’s board approved nearly INR 120 billion of investment for the first phase of expansion, which includes increasing refined metal capacity by 250 kilotonnes per annum and upgrading mines and milling infrastructure at multiple sites. These initiatives are aligned with the company’s projections for growth in zinc demand over the next five to ten years.
The company reported a 15 percent reduction in greenhouse gas emissions intensity in FY25 compared with a 2020 baseline. In 2024, Hindustan Zinc introduced EcoZen, a low-carbon zinc product manufactured using renewable energy. The company also became a member of the International Council on Mining and Metals (ICMM) in 2025.
Hindustan Zinc Limited, a Vedanta Group company, is the world’s largest integrated zinc producer and among the top five silver producers globally. It supplies to more than 40 countries and holds a market share of about 77 percent of India’s primary zinc market. The company has been recognised by the S&P Global Corporate Sustainability Assessment as the most sustainable metals and mining company for two consecutive years.
