The requirements for geomembranes used in heap leach pads include a high level of chemical resistance to withstand the aggressive chemicals used in the leaching process, excellent puncture resistance to prevent leaks, low permeability to minimize fluid migration, and UV resistance to withstand prolonged exposure to sunlight. Additionally, the geomembranes should have good tensile strength and flexibility to accommodate any subsidence or settlement in the heap leach pad.
The requirements for geomembranes used in heap leach pads include high chemical resistance to withstand the acidic or alkaline solutions used in the leaching process, excellent puncture and tear resistance to prevent leakage, UV resistance to withstand prolonged exposure to sunlight, and a smooth surface to ensure proper flow of liquids. Additionally, geomembranes must have high tensile strength and elongation properties to withstand stresses and movement in the heap leach environment.
The requirements for geomembranes used in heap leach pads typically include high chemical resistance, durability, flexibility, and impermeability to prevent the leakage of leachate. They should also have excellent UV resistance, puncture resistance, and mechanical stability to withstand the weight of the heap and any potential settlement. Additionally, geomembranes used in heap leach pads should be compatible with the surrounding soil and have low permeability to ensure effective containment of the leaching process.
