Acid and Alkali Resistant Geomembrane Liners for Tailings Management

Introduction to Geomembranes

Geomembranes are high-performance, impermeable synthetic liners designed to provide secure containment for industrial and environmental applications. Made from durable polymers like HDPE, LLDPE, and PVC, they offer superior chemical resistance, puncture resistance, and long-term durability—making them ideal for tailings storage facilities (TSFs) in mining operations.

Why Geomembranes Are Essential for Tailings Management

1. Prevent Leachate Contamination

✅ Impermeable Barrier – Blocks harmful chemicals, heavy metals, and acidic leachates from seeping into groundwater.
✅ Environmental Compliance – Meets EPA, ICMM, and global mining regulations for safe tailings disposal.

2. Enhance Structural Stability

✅ Prevents Erosion & Slope Failure – Reinforces tailings dams and storage ponds.
✅ Reduces Water Infiltration – Minimizes the risk of liquefaction and dam breaches.

3. Improve Water Recovery & Recycling

✅ Lined Collection Systems – Allow for efficient water recovery from tailings.
✅ Reduces Freshwater Consumption – Supports sustainable mining practices.

4. Long-Term Cost Savings

✅ Lower Maintenance – Resists UV degradation, chemical corrosion, and punctures.
✅ Extends Facility Lifespan – 30+ years of reliable performance with proper installation.

Geomembrane vs. Traditional Clay Liners

Recommended Geomembranes for Tailings Storage

1. HDPE Geomembrane (High-Density Polyethylene)

✔ Best for: Highly acidic/alkaline tailings
✔ Thickness: 1.5mm – 2.5mm
✔ Advantages: Extreme chemical resistance, high tensile strength

2. LLDPE Geomembrane (Linear Low-Density Polyethylene)

✔ Best for: Flexible, conformable lining in uneven terrain
✔ Thickness: 1.0mm – 2.0mm
✔ Advantages: Superior elongation, stress crack resistance

3. PVC Geomembrane (Polyvinyl Chloride)

✔ Best for: Temporary tailings ponds & cost-sensitive projects
✔ Thickness: 0.5mm – 1.5mm
✔ Advantages: Easy welding, good puncture resistance
