Hindustan Zinc, a Vedanta Group company and the world’s largest integrated zinc producer, has announced Board approval for India’s first zinc tailings reprocessing plant at Rampura Agucha in Bhilwara, Rajasthan.

Tailings, the finely ground remnants post mineral extraction, contain valuable residual metals. The new 10 million tonne per annum (Mtpa) facility, to be developed with an investment of Rs 3,823 crore, will extract zinc and silver from processed tailings, converting waste into resources. Completion is targeted within 28 months. Hindustan Zinc stated that reprocessing will enhance sustainability, reuse industrial byproducts, and promote a circular economy.

CEO Arun Misra said: “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.” Earlier, the Board had approved Rs 12,000 crore investment to double production capacity, aligning with India’s growing zinc demand.
