Geomembranes in Mining Applications - Engineered for Extreme Durability and Environmental Compliance
Geomembranes are indispensable in modern mining operations, providing robust containment solutions to manage hazardous materials, protect ecosystems, and ensure regulatory compliance. Our high-performance geomembranes are specifically designed to withstand the harsh conditions of mining environments, from acidic leachates to heavy mechanical stress.
Unmatched Chemical Resistance
Formulated with high-density polyethylene (HDPE) or linear low-density polyethylene (LLDPE) to resist:
Acidic/alkaline leachates (pH 1-14) from ore processing.
Heavy metals, cyanide, and solvents used in heap leaching or tailings.
Hydrocarbons and brine solutions in oil sands operations.
Third-party tested per ASTM D5322 for chemical compatibility, ensuring >90% retention of tensile strength after prolonged exposure.
Superior Puncture & Abrasion Resistance
Reinforced with multi-layer extrusion technology to withstand:
Sharp rocks, drilling debris, and heavy equipment (e.g., bulldozers, haul trucks).
Dynamic loads from settling tailings or seismic activity.
Puncture resistance >600 N (tested per ASTM D4833), critical for tailings pond liners and heap leach pads.
High-Temperature Stability
Engineered to perform in extreme thermal conditions:
Operating range: -50°C to +80°C.
Resists UV degradation and oxidative aging in open-pit mines or arid regions.
Carbon-black stabilization (2.5-3.0%) ensures UV resistance for exposed applications.
Low Permeability for Secure Containment
Hydraulic conductivity <1×10¹² cm/s (per ASTM D5887), preventing seepage of toxic fluids into groundwater.
Ideal for:
Tailings storage facilities (TSFs): Contain slurry waste from mineral processing.
Leachate collection systems: Capture and channel acidic runoff for treatment.
Customizable Configurations
Thickness: 1.0mm to 3.0mm, tailored to project load and longevity requirements.
Surface texture: Smooth, textured, or co-extruded options for enhanced friction and slope stability.
Widths up to 9m: Minimize field seams, reducing installation time and leakage risks.
Tailings Pond Liners
Primary or secondary containment layers to isolate toxic tailings slurry from soil and groundwater.
Heap Leach Pads
Lining systems for cyanide or sulfuric acid leaching operations, optimizing metal recovery while preventing contamination.
Process Water Ponds
Secure storage for recycled water used in ore processing, reducing freshwater consumption.
Waste Rock Dump Liners
Prevent acid mine drainage (AMD) by isolating sulfide-rich waste from rainwater and oxygen.
Emergency Spill Containment
Secondary barriers around fuel storage or chemical handling areas to mitigate environmental risks.
