Heap Leach Stockpile Area
Heap leach stockpile areas are systems used in metal mining, where valuable metals are extracted by spraying special chemicals onto the ore. The proper design and safe construction of these areas are crucial for minimizing environmental impacts and ensuring economic efficiency.
Geosynthetic Products Used and Their Functions:
- Geomembrane: Provides liquid and gas impermeability, preventing waste from leaking into the environment.
- Geotextile: Ensures filtration and drainage, offers mechanical protection, and regulates ground movements.
- Geosynthetic Clay Liner (GCL): Reinforced with bentonite clay, this material provides additional sealing.
- Geocell: Increases load-bearing capacity and stabilizes the ground.
- Geogrid: Strengthens soil and fill materials.
- Geonet: Facilitates drainage and water discharge.
- Geocomposite: Combines different geosynthetics to integrate impermeability and drainage features.
The integrated use of these products ensures that heap leach stockpile areas are safe, environmentally friendly, and long-lasting. The selection of products and combinations depends on the project's technical requirements and site conditions.
