Enhancing Safety and Operational Performance in Heap Leach Mining Operations
Improve operational performance and profitability of heap leaching facilities
Overcome Common Challenges for Optimal Heap Leach Operations
Heap leach mining is a highly effective and sustainable method used to extract valuable minerals from low-grade ore deposits. This process involves stacking crushed ore or run of mine (ROM) onto a pad or heap, and then using a leaching solution to extract the desired minerals. One of the major advantages of heap leach mining is its lower upfront capital cost and reduced environmental impact compared to traditional floatation processing methods. However, like any mining operation, heap leach mining faces several operational challenges. These challenges include efficient irrigation and percolation and effective monitoring and control of leach solutions. Fortunately, Emerson's state-of-the-art measurement instrumentation offers a solution to these challenges. With Emerson's measurement instrumentation, mining facilities can enhance safety, improve operational performance, and maximize the recovery of valuable minerals while minimizing environmental impact.
