Engineered geosynthetic systems for heap leach pads, tailings storage facilities, process ponds, evaporation ponds, and mine water management applications.
In geomembrane mining applications, HDPE geomembrane liners are used as separation barriers and are the most important components in heap leaching. Geomembranes must resist chemical attack, point loads under typical high stacking conditions, site-specific topography, site-specific climatic conditions, and site-specific construction conditions.

EarthShield Geomembrane Liner is an engineered geotechnical composite material system used for heap leaching ponds, tailings dams, processing ponds and evaporation ponds.
Challenges Facing Modern Mining Operations
Leakage Prevention: Prevent contamination of soil and groundwater.
Chemical Resistance: Withstand acidic and alkaline leaching solutions.
UV Durability: Long-term performance under harsh environmental conditions.
Slope Stability: Maintain liner integrity on steep slopes.
Water Management: Control process water and stormwater effectively.
Long Service Life: Reduce maintenance and replacement costs.
EarthShield high-performance, environmentally friendly geosynthetics are used by leading companies around the world to isolate contaminated waste. Mining operations generate large amounts of waste that can be harmful to the environment and human health. Improper management and disposal of mining waste and wastewater can lead to soil and water contamination, ecosystem damage, and long-term health risks. Our geosynthetics solutions provide effective fluid barriers, leachate control and other seepage control functions to ensure that mining waste is properly and safely managed while minimizing the impact on the environment.
Our geosynthetics install faster, perform better, are more environmentally friendly and are more cost-effective than using natural materials such as gravel, concrete or compacted clay.
EarthShield ® Mining geomembranes are high-density polyethylene geomembranes that meet or exceed the requirements of the GRI-GM13 standard specification. Available in smooth and rough textures and a variety of colors.
Modern mining operations rely on integrated geosynthetic systems to provide containment, drainage, protection, and reinforcement. These engineered solutions help reduce environmental risks while improving the long-term performance of mining infrastructure.
Geomembranes have many applications within the mining industry, and include:
Geosynthetic Solutions for Every Mining Stage:
Heap Leach Pads: Collection and containment of leaching solutions.
Tailings Storage Facilities: Tailings pond liner systems designed for long-term containment.
Process Ponds: Containment systems for process water and chemicals.
Evaporation Ponds: Prevent seepage and protect surrounding soil.
Heap leaching has become the preferred method of recovering minerals from low-grade ore from open-pit mines. Copper, gold, silver, and other metals are most common. The metal deposits are dissolved by chemicals applied to the top of the heap of ore, which eventually leaches to the bottom of the pile. Here a geomembrane liner captures the solution preventing it from migrating into the ground, before directing the solution by gravity to a collection system. The solution is sent to a refinery where the metal can be precipitated out and the solution sent back to the heap to be used again to dissolve more metal.
Disadvantages of Tailings Stockpiling
1. Since the tailings not only contain useful components such as re-separable metal ores and non-metal ores but also the non-re-separable tailings have many uses, so the storage of tailings will cause waste of useful components;
2. The storage of tailings not only occupies a large amount of cultivated land, but also easily causes environmental pollution, soil erosion, and vegetation damage in the mining area;
3. Tailings are easy to flow and collapse when they are stored, causing preparation damage and injury accidents. Especially in the rainy season, it is very easy to cause collapse and landslides. The tailings dam body is high, and there are hidden dangers of unsafety;
4. The composition of tailings and residual beneficiation agents seriously damages the ecological environment, especially the tailings containing heavy metals. The acid water produced by sulfide will further leach heavy metals, and the loss of heavy metals will cause harm to the entire ecological environment.
