Heap Leaching

Heap leaching is commonly used in gold, copper, and uranium mining operations to extract minerals from ore. The process typically involves heaping crushed ore on a geomembrane liner and then adding chemicals to the heap by sprinkling or drip irrigation.

Layfield Environmental Containment can provide several types of heap leach geomembranes. We recommend Enviro Liner® 4000 and Enviro Liner® 6000HD in 40 and 60 mil thicknesses for heap leaching applications. These geomembranes are highly flexible and are well suited for placement under pads of blasted rock.

Both Enviro Liner® 4000 and 6000HD are resistant to cyanide, sulfuric acid, and arsenic and are easily prefabricated and installed. Enviro Liner® 6000HD is fortified with an advanced UV/AO package and is ideal for long-term exposed applications. Enviro Liner® 4000 is also suitable for channels and ponds and for fabricating floating covers for pregnant solution ponds.

"We do appreciate you coming all this way to see us. We get other supplies just showing up and considering we have 50 construction people to supervise we don't have time for them. You did it right by setting it up in advance and letting us know your takeaways. This made for beneficial use of our time." Matthew, Civil & Commercial Construction Company
