Mining Heap Leach Pads Applications from AGRU
A geomembrane available in two resin types: HDPE and LLDPE. AGRU Drain Liner is best suited for single- or double-lined projects such as landfills, waste ponds, lagoons, mining heap leach pads, and process ponds where containment and leak detection is crucial.
Geomembranes used in heap leach SX-EW mining_百度文库
2010-10-6 · CONCLUSIONS Geosynthetics are used in the design and construction of various mining facilities for process solution containment (heap leach pads, solution ponds and tailings impoundments). Due to the nature and location of mining projects, the performance envelope of geosynthetic materials is often pushed beyond the limits of typical design procedures, testing, and construction methods.
Improving the Stability of Heap Leach Pads
Figure 1. Non-planar features used to improve resistance to sliding and overall slope stability By Allan J. Breitenbach, P.E., and Chris Athanassopoulos, P.E. Geosynthetic composite liner systems, consisting of geosynthetic clay liners (GCLs) underlying geomembrane liners, are seeing increased use in heap leach pads due to faster construction time and improved liquid containment compared
