CIMIC Group companies Sedgman and Leighton Asia have been awarded separate contracts by Hindustan Zinc Limited (HZL), the world’s largest integrated zinc producer and one of the top 5 silver producers globally, to support the delivery of India’s first zinc tailings recycling facility at Rampura Agucha Mines (RAM) in Rajasthan, India.
This milestone project reflects CIMIC’s strategic commitment to enabling the global energy transition through sustainable infrastructure and critical minerals development. With over 45 years’ experience in processing and delivering minerals essential to clean energy, advanced manufacturing and digital infrastructure, Sedgman has delivered more than 630 studies and projects globally – including 20 in zinc since 2014.
Sedgman will deliver engineering services and offshore equipment procurement under an offshore contract. Leighton Asia – a long-standing infrastructure delivery partner with an established presence in India – will manage the project’s construction and onshore procurement under a separate contract. The contracts will generate revenue of approximately A$400 million for CIMIC.
ACS Group and HOCHTIEF Chief Executive Officer and CIMIC Group Executive Chairman Juan Santamaría said:
“This project highlights Sedgman’s leadership in minerals processing and Leighton Asia’s proven capability in infrastructure delivery. It reflects our Group’s strategic commitment to supporting the global energy transition through critical minerals development. Modern tailing reprocessing unlocks new opportunities to recover essential minerals that power clean energy technologies and digital infrastructure.”
Sedgman Managing Director Grant Fraser said:
“By leveraging our extensive track record in tailings reprocessing, we are pleased to support the extraction of critical minerals from waste, to deliver a circular economy approach to providing minerals for the clean energy transition. Our technical expertise, project delivery, and operations experience allows us to deliver end-to-end solutions to unlock value for clients like Hindustan Zinc and support a transition towards more sustainable minerals extraction.”
Leighton Asia Managing Director Brad Davey said:
“By combining our international experience with local knowledge, we’re pleased to partner with Hindustan Zinc on a project that not only advances India’s mining infrastructure but also supports the region’s growth while creating opportunities for local communities through employment and procurement.”
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 the nation’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.”
