Improved Tailings Dam Operations by Leveraging Measurement Instrumentation
Enhancing mining operations, ensuring improved efficiency and safety in tailings dam management.
Optimal flow rates to monitor water levels and sediment concentrations
Tailings dams are indispensable structures in mining operations, serving as vital containment systems for mineral processing waste. Yet, managing these facilities comes with an array of challenges. Operators must grapple with achieving and maintaining optimal flow rates, monitoring water levels, and controlling percent solids in tailing slurries. Complicating matters further are pressures variations, and sediment buildup that can significantly impact the efficiency and safety of tailings dam operations. To tackle these complexities, mining operators are increasingly relying on advanced sensor technologies. Tailing dam flow and slurry density sensors enable operators to gather real-time information and insights crucial for informed decision-making. With Emerson's Measurement Instrumentation, operators can achieve reliable monitoring and control, empowering them to proactively address issues and optimize tailings dam performance.
