Geomembranes and geotextiles are most commonly used in the mining sector for waterproofing the heap leach pads in metallic mining (Gold, Silver, Copper etc.), and to prevent the acids used in the mineral leaching from contaminating the subsoil in non-metallic mining (Iodine Lithium, etc.).
The main geosynthetic applications in mining are:
- Leaching pads
- Waste dams
- Secondary barriers in product deposits
- Evaporation pools
- Brine ponds
- Concentrates ponds
- Floating covers
- Tanks for chemical products
- Rain protection
- Bioleaching bacteria
- Bladder tanks
- Soil reinforcement and stabilisation
