On May 28, 2025, the 2025 National Forum on Innovative Technologies in Hydrometallurgy, themed “Green Momentum for the Future—Leading with Intelligence in Hydrometallurgy,” was grandly held in Wuhan. As a leading enterprise in China’s environmental engineering materials sector, HaoYang Environmental Co.,Ltd. (hereinafter referred to as “HaoYang Environmental”) was invited to attend, and its engineer, Li Hongzhen, delivered a special report titled “Research on the Application of Environmental Engineering Materials in Impermeability Projects for Hydrometallurgy,” offering innovative solutions to support the industry’s green transformation.

Focusing on the innovative application of eco-friendly materials Solving the Challenges of Impermeability in Hydrometallurgy

In the field of hydrometallurgy, the risk of heavy-metal solution leakage during production has long constrained the industry’s sustainable development. Leveraging years of innovative expertise, Haoyang Environment has independently developed a “…”. Geotextile membrane for hydrometallurgy This has become the central highlight of this report. The report indicates that, by optimizing its antioxidant system, the material demonstrates significant advantages in highly acidic, highly alkaline, and strongly oxidizing environments (such as hydrogen peroxide and ozone), with an OIT retention rate after 60 days. Up to over 95% , retention rate of mechanical properties (strength, elongation) Over 95% , the resistance to degradation has been comprehensively enhanced, enabling long-term tolerance to the combined effects of severe chemical corrosion and oxidative degradation.

Li Hongzhen emphasized in his report: “ Seepage-control engineering is the lifeline of green hydrometallurgical production. The innovative, environmentally friendly, specialized seepage-control materials we manufacture not only… Satisfy GB 18597-2023 The “Standard for Pollution Control on the Storage of Hazardous Wastes” imposes stringent requirements. ， In the future, we will also leverage modular construction techniques, robotic welding, intelligent monitoring systems for impermeable materials, and high-performance nanocomposite membranes, among other approaches. “Driving the industry toward intelligent transformation.”

Leading the industry’s green transformation

During the forum, the Haoyang Environmental booth showcased more than 20 specialized impermeable materials for hydrometallurgy and a variety of complex applications. These include six major product categories—acid- and alkali-resistant geomembranes, three-dimensional composite drainage mats to prevent siltation, sodium‑based bentonite waterproofing blankets in powder form, high‑performance spray‑applied impermeable materials, and more—covering all wet‑process metallurgy applications, such as red mud stacks, tailings ponds, and leaching tanks.

This forum is hosted by Northeastern University, Wuhan University of Science and Technology, Wuhan University of Technology, Editorial Department of “Hydrometallurgy” United Hosted by, it brings together participants from research institutes, design firms, and companies across the industry chain. 300 The remaining delegates.

Through this forum, Haoyang Environment has once again demonstrated its technological leadership in the environmental engineering sector. As the “dual carbon” goals gain momentum, the company, driven by innovation, is developing end-to-end seepage‑control solutions for the hydrometallurgical industry—spanning risk assessment, design, construction, and operations—and thereby empowering the global green mining transition.
