Heap Leach Pond Liners/Tailing Waste Dam Liners
Heap leaching is an industrial mining process to extract precious metals, copper, uranium, and other compounds from ore (usually it is low-grade ore) via the lixiviant spray technique which will produce a series of chemical reactions that absorbs specific minerals and then re-separate them from pregnant solution flowed from the heap leaching base after their division from other earth materials.
Tailings are remains from the processing of the ores. A tailings dam is typically an earth-fill embankment dam used to store tailings which are produced in the heap leaching process after separating the valuable fraction. No matter for the heap leaching pads, solution ponds, tailing dams, All of them are needed to be lined to minimize the potential for toxic lixiviant release into the environment.
