UDAIPUR, India, Jan. 23, 2026 — India based Hindustan Zinc Limited, a Vedanta Group company and the world’s largest integrated zinc producer, announced today that it has awarded contracts to CIMIC Group companies Sedgman and Leighton Asia for the development of India’s first zinc tailings recycling facility at its flagship Rampura Agucha Mines (RAM) in Rajasthan.
The unique facility at Rampura Agucha will utilize sophisticated processing methods to extract metals like zinc and silver from previously mined tailings, converting historical waste into useful materials and promoting a circular economy model for the mining sector.
Arun Misra, CEO – Hindustan Zinc Limited, said: “India’s next phase of industrial growth will be defined not just by how much we mine, but by how intelligently we use what we already have. This project represents a fundamental shift in mining, from extraction to optimisation, and from linear consumption to circular value creation. By establishing India’s first zinc tailings recycling facility at global scale, Hindustan Zinc is creating a blueprint for how legacy resources can be re-engineered into future supply, strengthening India’s critical minerals security. Our collaboration with Sedgman’s global minerals processing expertise and Leighton Asia’s on-ground infrastructure execution brings together the best of technology and delivery to set new benchmarks for responsible mining.”
This initiative is a component of the company’s strategy to increase its production capacity twofold. In August, Hindustan Zinc’s Board approved an investment of up to ₹3,823 crore for the development of a 10 million tonnes per annum (Mtpa) zinc tailings reprocessing facility at Rampura Agucha, with a target completion date of 28 months from the start date.
Juan Santamaría, ACS Group and HOCHTIEF Chief Executive Officer and CIMIC Group Executive Chairman, said: “This project highlights Sedgman’s leadership in minerals processing and Leighton Asia’s proven capability in infrastructure delivery. It reflects CIMIC Group’s strategic commitment to supporting the global energy transition through critical minerals development. Modern tailings reprocessing unlocks new opportunities to recover essential minerals that power clean energy technologies and digital infrastructure.”
