Several types of geomembranes are available for use in mining applications, each offering unique properties and characteristics to suit specific project requirements. HDPE) Geomembranes: HDPE geomembranes are widely used in mining due to their excellent chemical resistance, high tensile strength, and durability. They provide effective containment and resistance to puncture, tearing, and UV degradation. HDPE geomembranes are available in various thicknesses and can be either smooth or textured, depending on the application. Smooth HDPE geomembranes are typically used in ponds or storage facilities, while textured versions offer increased frictional resistance and are suitable for slope stabilization or lining applications.Geomembranes: LLDPE geomembranes are similar to HDPE geomembranes but have lower density, resulting in improved flexibility and elongation properties. LLDPE geomembranes are commonly used in mining applications where superior elongation and flexibility are required, such as in landfills or tailings ponds that experience settlement or differential movement. They provide excellent chemical resistance and are resistant to stress cracking.
PVC geomembranes offer good chemical resistance and high puncture resistance. They are often used in mining applications where chemical exposure is a concern, such as in wastewater treatment ponds or heap leach pads. PVC geomembranes are available in different formulations to suit specific chemical environments and can be fabricated with various additives to enhance UV resistance and flexibility. EPDM geomembranes are synthetic rubber-based materials that offer excellent weathering resistance, UV resistance, and flexibility over a wide range of temperatures. They are commonly used in mining applications where exposure to extreme weather conditions, such as freeze-thaw cycles, is expected. EPDM geomembranes are often used in heap leach pads, evaporation ponds, or covers for tailings ponds.
