How Emerson's Solutions Advance Leach Pad Control

Emerson offers advanced measurement and control solutions to improve the efficiency, safety, and sustainability of heap leaching operations in mining. These technologies provide continuous, real-time data that optimize raffinate solution distribution, maximize metal recovery, and support environmentally responsible operations. • Challenges in traditional heap leaching: Managing raffinate flow across expansive leach pads is complex, with too little solution reducing ore recovery and too much increasing the risk of environmental hazards, safety issues, and inefficient resource utilization. • Innovative monitoring technology: Emerson's wireless instrumentation skids—featuring pressure transmitters, orifice plate flow meters, and regulating valves integrated through WirelessHART networks—deliver continuous monitoring and precise control of raffinate flow, generating high-volume data for improved visibility without costly wiring. • Benefits of Emerson's solution: Enhanced process control and real-time insights improve copper recovery, detect issues such as leaks and blockages, reduce operational risk, and support safer, more efficient, and environmentally compliant leach pad operations.
