Hindustan Zinc Limited, part of the Vedanta Group and the largest integrated zinc producer globally, has contracted CIMIC Group companies Sedgman and Leighton Asia to develop India’s first zinc tailings recycling facility at its Rampura Agucha Mines in Rajasthan. This facility will use advanced technologies to recover valuable metals, transforming tailings previously considered waste into resources. The project supports India’s aims for resource efficiency and a circular economy, essential for strengthening the domestic supply of critical minerals. CEO Arun Misra stated this initiative signifies a shift towards optimized mining practices. The facility, backed by an investment of ₹3,823 crore, aims to double Hindustan Zinc’s production capacity within 28 months.
Hindustan Zinc Limited India’s
Sedgman will handle engineering and equipment procurement, while Leighton Asia manages construction, contributing to India’s clean energy and infrastructure goals. The overall plan aligns with projected increases in zinc demand due to infrastructure and steel sector growth Hindustan Zinc Limited, India’s largest producer of zinc and silver, has taken a landmark step toward sustainable mining by partnering with global engineering and construction major CIMIC Group to establish India’s first zinc tailings recycling facility. This initiative marks a significant shift in how mining waste is perceived in the country, transforming tailings from an environmental liability into a valuable resource. As India pushes forward with its sustainability and net-zero ambitions.
This project positions Hindustan Zinc as a frontrunner in adopting circular economy practices within the metals and mining sector Mining tailings, which are residual materials left after ore processing, have traditionally posed serious environmental challenges due to land use, water contamination, and long-term storage risks. By recycling zinc tailings, Hindustan Zinc aims to reduce waste accumulation while extracting additional value from previously discarded material. This initiative aligns closely with global best practices in sustainable resource management and reinforces India’s growing commitment to responsible industrial development. Similar green mining approaches are gaining momentum across the country The collaboration with CIMIC Group brings advanced.
Utting-Edge Technology
Engineering expertise and global project execution capabilities to the table. CIMIC has extensive experience in delivering complex industrial and resource recovery projects across multiple geographies. Through this partnership, the zinc tailings recycling facility will leverage cutting-edge technology to recover metals (India) efficiently while minimizing environmental impact. The project is expected to set new benchmarks for waste management in the Indian mining industry and could serve as a replicable model for other mineral producers From a sustainability perspective, the facility is expected to significantly lower the environmental footprint of zinc production. Recycling tailings reduces the need for fresh mining, conserves natural resources, and limits land degradation.
It also supports water stewardship by reducing contamination risks associated with traditional tailings storage. These outcomes resonate strongly with India’s broader sustainability goals and complement ongoing efforts to integrate renewable energy and cleaner technologies into heavy industries The zinc tailings recycling project also strengthens Hindustan Zinc’s commitment to a circular economy. Instead of following the linear “extract-use-dispose” model, the company is embracing resource efficiency by reprocessing waste streams. This approach not only improves operational efficiency but also enhances long-term economic resilience. By extracting additional zinc and associated minerals from tailings, the company can unlock hidden value while extending the life of existing mines.
Supporting Ancillary Industries
Economically, the facility is expected to generate multiple benefits. It will create skilled employment opportunities in advanced processing, environmental management, and plant operations. The project will also contribute to regional development by supporting ancillary industries and services. For investors and stakeholders, the initiative demonstrates Hindustan Zinc’s proactive risk management strategy, as sustainable practices increasingly influence regulatory frameworks, financing decisions, and global market access On a national level, the project aligns with India’s push toward sustainable industrialization and responsible waste management. The government has been encouraging industries to adopt cleaner technologies and reduce their environmental impact.
Particularly in resource-intensive sectors like mining and metals. By pioneering zinc tailings recycling, Hindustan Zinc and CIMIC are supporting these policy objectives while reinforcing India’s position as an emerging hub for sustainable industrial innovation Globally, tailings recycling and reprocessing are gaining traction as mining companies seek to address legacy waste and meet stricter environmental standards. International organizations such as the International Energy Agency and the World Bank have emphasized the importance of sustainable resource use and waste reduction in achieving climate and development goals . Hindustan Zinc’s initiative reflects these global trends while adapting them to India’s unique industrial context Technology will play a central role in the success of this facility.
Integration Of Such Technologies Underscores
Advanced separation, filtration, and recovery processes will enable efficient extraction of zinc from tailings while ensuring minimal environmental discharge. Continuous monitoring systems are expected to enhance safety and compliance, setting new operational standards for the sector. The integration of such technologies underscores the growing convergence of mining, engineering, and environmental science The zinc tailings recycling facility could pave the way for similar projects across India’s mining landscape. If successful, it may encourage other producers to invest in tailings reprocessing and industrial waste recovery. This shift could significantly reduce the environmental burden of mining while supporting India’s long-term resource security.
The partnership between Hindustan Zinc and CIMIC to establish India’s first zinc tailings recycling facility represents a transformative step for the mining industry. It demonstrates how (India) innovation, sustainability, and economic growth can coexist when companies adopt forward-looking strategies. As India accelerates its transition toward greener industries, such initiatives will play a crucial role in shaping a more resilient and responsible industrial future.
