In the world of mineral processing, tailings storage facilities (TSFs) are a necessary evil. They store the waste generated from mining operations, but they also pose significant risks to the environment, local communities, and the companies that operate them. A recent study published in *Territorium: Revista Portuguesa de riscos, prevenção e segurança* (Portuguese Journal of Risks, Prevention and Safety) offers a new tool to help manage these risks more effectively. The research, led by Danielle Menezes of the Federal University of Ouro Preto’s Nucleo of Geotechnics, introduces the Risk Control Management System (RCMS), a comprehensive approach to assessing and mitigating risks associated with TSFs.
The RCMS is based on the Global Industry Standard on Tailings Management (GISTM) protocols, which provide a framework for evaluating tailings governance and management. The system assigns a score that measures the performance of TSF management, indicating the maturity level of risk controls. This, in turn, influences the likelihood or impact of a failure. “The RCMS allows us to quantify the effectiveness of control measures,” Menezes explains. “This is crucial for identifying areas of improvement and ensuring that TSFs are managed as safely and responsibly as possible.”
The methodology was applied to eight TSFs located in two countries, allowing the construction of a Risk Control Maturity Matrix. This matrix, along with a table demonstrating improvement opportunities, provides a clear roadmap for enhancing TSF management and governance processes. “Our goal is to help companies not only meet regulatory requirements but also to go beyond compliance and adopt best practices,” Menezes adds.
The commercial implications for the energy sector are significant. Mining operations are a critical part of the supply chain for many energy technologies, from lithium for batteries to rare earth elements for wind turbines. Effective management of TSFs can reduce the risk of costly accidents, improve regulatory compliance, and enhance the social license to operate. This, in turn, can lead to more stable and sustainable supply chains, benefiting the entire energy sector.
The research also highlights the importance of continuous improvement in risk management. By regularly assessing and updating control measures, companies can adapt to changing conditions and emerging risks. This proactive approach can help prevent incidents and mitigate their impact if they do occur.
The RCMS offers a promising tool for improving the safety and sustainability of TSFs. As the energy sector continues to rely on minerals and metals, the need for responsible mining practices will only grow. This research could shape future developments in the field, promoting a more robust and resilient approach to tailings management. As Menezes puts it, “The RCMS is not just about managing risks; it’s about building a culture of safety and responsibility within the industry.”
