The Critical Challenge: Containing Aggressive Smelter Byproducts
Mining and smelting operations generate highly corrosive effluent streams laden with sulfuric acid, heavy metals (Cu, Zn, Ni, Pb), dissolved salts, and elevated temperatures. Traditional containment materials degrade rapidly, risking:
Groundwater Contamination from arsenic/cyanide leaks
Regulatory Non-Compliance with EPA RCRA/ CERCLA standards
Infrastructure Corrosion costing millions in unplanned repairs
Production Shutdowns due to environmental incidents
Our Solution: Metallurgical-Grade HDPE Geomembranes
Engineered for extreme smelter environments, our high-density polyethylene liners deliver unmatched chemical resistance and structural integrity for:
Acid Leachate Ponds
Process Water Balancing Tanks
Spent Electrolyte Containment
Slag Slurry Impoundments
Emergency Overflow Basins
1. Unrivaled Chemical Resistance
Withstands pH 1-14 extremes – stable in concentrated H₂SO₄, HCl, NaOH solutions
Immune to heavy metal ion degradation (Cu²⁺, Zn²⁺, Ni²⁺ permeation <0.001 g/m²/day)
Resists oxidizers like hydrogen peroxide and chlorine bleaches
2. Thermal Stability Under Process Conditions
Operational range: -60°C to +80°C
Maintains flexibility during steam surges and freezing slag discharges
Low thermal expansion coefficient prevents stress cracking
3. Engineered Mechanical Robustness
| Property | Smelter-Grade Specs | Industry Standard |
|---|---|---|
| Thickness | 2.0-3.0 mm | 1.5 mm |
| Puncture Resistance | ≥700 N | 400 N |
| Tensile Strength | ≥35 MPa | 25 MPa |
| Stress Crack Resistance | ≥1500 hrs (ASTM D5397) | 300 hrs |
4. Seam Integrity Assurance
Double-Track Fusion Welding with 100% spark testing
Seam strength ≥90% parent material
Robotic welding available for zero-defect critical zones
5. Cost-Effective Lifecycle Protection
50+ year service life reduces replacement frequency
Prevents $250k+/acre remediation costs from containment failures
Allows thinner concrete sub-layers (saves 30% on civil works)
Defense-in-Depth System Design:
Geotextile Cushion (400g/m²) – Prevents puncture from slag debris
HDPE Primary Liner (2.5mm) – Chemical barrier
Leak Detection Grid – 30m spacing sensors
Secondary HDPE Liner (1.5mm) – EPA-mandated redundancy
Smelter-Specific QA/QC:
Bath Testing for seam integrity using 5% HCl solution
Spark Testing at 15kV for micro-pinhole detection
Differential Scanning Calorimetry validates resin formulation
Meets EPA 40 CFR 264.221 for surface impoundments
Certified to EN 15382 for hazardous liquid containment
NSF/ANSI 61 for potable water contact (dual-use ponds)
Proven in Extreme Environments:
“After 12 years containing pH 0.8 sulfuric acid effluent at 65°C, our 2.5mm HDPE liner shows <0.1% elongation loss and zero seam failures.”
