• Heap leaching Wikipedia

    Heap leaching is an industrial mining process used to extract precious metals, copper, uranium, and other compounds from ore using a series of chemical reactions that absorb specific minerals and re-separate them after their division from other earth materials. Similar to in situ mining, heap leach mining differs in that it places ore on a liner, then adds the chemicals via drip systems to the

  • Geomembranes for heap leach pads [2020] Atarfil

    Liners for Heap leach pads In mining, the leaching process used to obtain metals and minerals involves the use of chemical products and processes that can contaminate the environment. This creates a requirement for secure containment barriers and drainage systems using geosynthetics.

    The site consists of an off/process facility, an open-pit mine, an overburden dump, sulfide and oxide stockpile dumps, leach pads, tailings and waste rock piles, and evaporation ponds. Naturally occurring radioactive materials including uranium, thorium, and radium, are present at the site and have become concentrated in some areas due to mining processes.
