Comminution, the process of crushing and grinding ore to extract valuable minerals, is energy-intensive, consuming up to 50% of a mine’s energy (McKinsey, 2024). Advanced technologies are enhancing comminution efficiency, reducing costs, and improving sustainability in mining operations.
Real-time monitoring systems, using sensors and IoT, optimize comminution by tracking variables like ore hardness and particle size. These systems adjust crusher and mill settings dynamically, improving throughput and reducing energy waste by up to 15% (Mining Technology, 2024). For example, Metso’s SmartTag system monitors ore characteristics, enabling precise process adjustments (Metso, 2023).
AI and machine learning further boost efficiency. AI algorithms analyze historical and real-time data to predict optimal grinding conditions, minimizing over-grinding and enhancing liberation efficiency (ScienceDirect, 2024). BHP’s use of AI-driven comminution models has improved mill performance by 10% (E & MJ, 2023). Digital twins simulate comminution circuits, allowing virtual testing of configurations to maximize output (IBM, 2024).
High-pressure grinding rolls (HPGR) and advanced mill designs, like stirred mills, reduce energy consumption compared to traditional ball mills, cutting costs and emissions (McKinsey, 2024). Automation systems, such as Weir’s Enduron HPGR, ensure consistent operation, reducing downtime (Weir, 2023). These technologies also enhance safety by minimizing manual interventions in hazardous environments (E & MJ, 2023).
Challenges, including high implementation costs and data integration complexities, remain (Gartner, 2022). Nonetheless, technology is driving more efficient, sustainable comminution processes.
