Haoyang Environmental Launches Special Geomembrane for Hydrometallurgy – Engineered for Extreme Corrosion Resistance

Haoyang Environmental Co., Ltd., a leading global provider of high-performance geosynthetic solutions, officially released its special geomembrane designed exclusively for hydrometallurgy applications. Built to solve the long-standing pain points of standard geomembranes in highly corrosive mining environments, this innovative product delivers exceptional chemical resistance, extreme condition adaptability, and long service life, making it the ideal containment solution for modern hydrometallurgical operations worldwide.

Hydrometallurgy has become a core process in modern mining and metal recovery, but it places extremely high demands on containment materials. The leachate used in hydrometallurgy typically contains strong oxidizing media such as hydrogen peroxide and ozone water, along with high-concentration acids, alkalis, and heavy metal ions. Standard geomembranes struggle to withstand such harsh conditions.

In real-world operations, conventional liners often face rapid antioxidant depletion, resulting in serious chemical corrosion, premature cracking, and leakage. Many standard geomembranes lose more than 50% of their oxidation induction time within months, with service life dropping to just 1–2 years. Leakage incidents lead to metal loss, severe soil and groundwater pollution, production shutdowns, and heavy environmental fines—creating huge hidden costs for mining operators.

Additional challenges include high-temperature fluids (often exceeding 60°C), high pressure, mechanical abrasion, and even low-temperature brittleness in certain operating environments. Standard geomembranes tend to deform, tear, or fracture under these stresses, resulting in frequent maintenance and short replacement cycles.

To address these industry-wide challenges, Haoyang’s R&D team developed a specialized hydrometallurgy geomembrane using advanced 5-layer co-extrusion blow-molding technology and a proprietary anti-corrosion formula. This product redefines performance standards for corrosive mining containment systems.

Core Advantages of Haoyang Hydrometallurgy Geomembrane

1. Ultra-High Chemical Corrosion Resistance

The geomembrane uses a specially engineered anti-oxidation formula that significantly improves resistance to hydrogen peroxide, ozone water, and strong oxidizing environments. Its ability to withstand synergistic corrosion from high-concentration acids, alkalis, salts, and heavy metal solutions is three times higher than that of standard geomembranes. It effectively prevents chemical corrosion, perforation, and premature failure, ensuring stable containment performance.

2. Superior Adaptability to Extreme Working Conditions

Combining 5-layer co-extrusion technology with a nano-reinforced functional layer, the geomembrane maintains excellent dimensional stability and mechanical strength under high temperatures (above 60°C), high pressure, and continuous abrasion. It also resists low-temperature embrittlement, making it suitable for diverse climate zones and harsh on-site conditions.

3. Long Service Life & Reduced Maintenance

Designed for a service life of 15–20 years in aggressive hydrometallurgical environments, this specialized liner greatly extends replacement cycles. Maintenance frequency is reduced by up to 60%, lowering downtime, labor costs, and material expenses. For mining operators, this means higher operational efficiency and lower total cost of ownership.

4. Full Protection Against Leakage & Environmental Risk

By eliminating premature corrosion and fracture, Haoyang’s hydrometallurgy geomembrane prevents leachate leakage, precious metal loss, and ecological contamination. It helps enterprises comply with global environmental regulations, avoid penalties, and fulfill their sustainable mining commitments.

Haoyang’s hydrometallurgy geomembrane is produced on advanced 5-layer co-extrusion lines, ensuring consistent thickness, uniform performance, and excellent weldability. It supports customized specifications in width and thickness to match different leach tanks, storage ponds, and recovery systems.

As global demand for responsible and efficient mineral processing continues to rise, the need for reliable, corrosion-resistant containment solutions has never been greater. Haoyang Environmental has long focused on solving real engineering challenges through material innovation and process optimization. This new hydrometallurgy-specific geomembrane further strengthens the company’s leadership in high-end, application-driven geosynthetic products.

With a strong global sales and service network, Haoyang provides reliable supply, on-site technical support, and customized solutions for mining projects in Africa, Southeast Asia, South America, and other major mining regions.

Haoyang Environmental remains committed to its mission: Make the earth cleaner, make people healthier. By launching this corrosion-resistant hydrometallurgy geomembrane, the company continues to deliver professional, durable, and safe containment solutions for the global mining industry.
