Execution of the Geomembrane Lining Project at the Saveh Copper Mine Heap Leaching Pad
The geomembrane lining project for the heap leaching pad at the Saveh copper mine, spanning an area of approximately 40,000 square meters, was successfully executed. The process initiated with rigorous subgrade preparation and surface leveling, during which any sharp stones, debris, or structural protrusions capable of puncturing or damaging the geomembrane liner were meticulously removed.
Subsequently, the geomembrane sheets were seamlessly bonded using advanced thermal fusion welding and ultrasonic techniques, engineering a completely continuous and impermeable containment layer. This high-performance barrier effectively prevents the subsurface leakage of highly corrosive heap leaching acid solutions and Pregnant Leach Solutions (PLS).
Following the deployment, strict Construction Quality Assurance (CQA) protocols—including non-destructive leak location testing and exhaustive weld integrity inspections—were conducted. These measures verified the long-term optimal performance of the lining system, ensuring the project's absolute compliance with international safety regulations and environmental protection standards.
