Heightened environmental awareness and increased industry regulations have enforced the use of geomembranes in the mining sector, including metal mining, non-metallic mineral mining and energy mining. Common environmental impacts include changes in local water balance; containment of toxins in tailings ponds or leaching solutions; tailings ponds or leaching pads stability failure; potential acid generation from waste rock and pit walls; heavy metal leaching from acid mine drainage; cyanide solution containment at heap leach operation and contamination of surface water and groundwater from discharge of acid mine drainage including heavy metals originating in ore and tailings, and organic chemicals and cyanide originating from milling processes.
Layfield has been a major supplier to the mining sector for the past 35 years. Layfield geomembranes have been used as environmental barriers for tailing ponds, heap leach pads, processed water containment, wastewater runoff ponds, soil remediation, secondary containment, floating covers and tailings cap enclosures. Our Enviro Liner 6000HD technology is an excellent choice for most major mining containment applications. Enviro Liner 6000HDis a high performance, fortified polyolefin alloy geomembrane, which provides excellent chemical resistance, durability and longevity.
