Heap leaching is an industrial mining process to extract precious metals components from ore. The mined ore is crushed into smaller chunks and heaped on an impermeable geomembrane andor clay lined leach pad where it can be irrigated with a leach solution e. g. cyanide or sulphuric acid to dissolve the valuable metals.
Liners for Heap leach pads In mining, the leaching process used to obtain metals and minerals involves the use of chemical products and processes, these types of materials are highly hazardous for the environment. This creates a requirement for secure containment barriers and
Apr 01, 2010 Heap leach pads are used in the mining industry as an integral component for metal extraction and processing. The design of modern heap leach pads utilize an engineered liner system that often is a blend of natural and geosynthetic materials in order to achieve a desired performance, such as ore heap stability, solution drainage, and efficient recovery.
The 83-acre heap leaching pad, designed and constructed by Bechtel Civil and Mineral Corporation, puts the liner to the ultimate test. The chemical action of sulfuric acid, combined with temperatures reaching 160 F on the black surface, can seriously soften most liner materials.
Aug 28, 2020 Evaporation ponds and heap leaching are the largest applications of HDPE geomembrane liner in mining, and heap leaching is the most complex. Water is pumped through wells into and out of the underground salt formations bringing the brine solution to the surface, where the sun evaporates the water, leaving the salt for recovery.
The most known leach pad liner failure in the mining industry is Summitville in Southern Colorado. Although no known heap stack failures occurred at Summitville, there was a possibility that the exposed pad liner may have been damaged by an avalanche debris slide during early stacking operations.
Leach Pad or Heap Leach Pad is a pond for the process where precious metals like gold, silver, copper or uranium is extracted from their ore. The ore is placed on the geomembrane a base pad with a heap and sprinkling a leaching solvent. As a solvent can be used cyanide or acids.

Heap Leach Mining Pads. Heap Leaching is an industrial mining process wherein large piles of mineralized ore are irrigated with various chemicals including alkaline, acidic or cyanide solutions which leach the intended mineral out of the rock and into solution. The mineral bearing solution trickles down through the rock pile and eventually gathers on an underlying, impermeable liner.
Heap leaching is among the most cost-effective mining applications with substantially lower operating and capital costs compared with other forms of leach processing. It enables the operation to run at low costs for the long-term. Heap leaching utilize either a single or double composite liner.
