3.2 GEOSINCERE Geomembrane Liner for Heap Leaching Pond
A Heap Leach Pond is a specially designed surface facility used in the mining industry as part of the heap leaching process. Heap leaching is a metallurgical technique for extracting valuable metals from low-grade ores by placing ore on a specially prepared pond and applying a leaching solution. The leaching solution percolates through the heap, dissolving and extracting the target metals from the ore. In heap leach mining operations, GEOSINCERE geomembrane HDPE liners are often used to line the pads where ore is placed for leaching. The HDPE liners can protect the leachate from contaminating the underlying soil and groundwater.
Heap leach pads are designed to accommodate the stacking of ore in a way that maximizes exposure to the leaching solution. The ore is typically crushed and placed on the pad in layered heaps.
Leaching solution, usually containing chemicals such as cyanide or sulfuric acid, is applied to the top of the ore heap. This solution percolates through the ore, dissolving the target metals (such as gold, silver, copper) as it moves downward.
The primary function of a Heap Leach Pad is to provide a controlled environment for the heap leaching process, ensuring efficient metal recovery while minimizing environmental impact.
The key functions include:
3.2.1 Facilitating Leaching Process
