From May 5 to 7, 2026, the 30th ALTA International Mineral and Metal Processing Conference successfully concluded in Perth, Australia. Under the theme "Sustainable Mining: Driving Decarbonization, Efficiency, and Responsible Resource Management," this conference brought together leading enterprises and technical experts from the global mining, metallurgy, materials, and engineering sectors. As a highly influential professional event within the global mining and metallurgy sphere, the ALTA conference has established itself as a premier platform for technical exchange and innovation within the hydrometallurgy industry.
Haipu New Materials made a grand debut at Booth 30, presenting its comprehensive, end-to-end separation and purification solutions for mineral resource development. Leveraging its strengths in independently developed core materials, mature engineering schemes, and green, low-carbon technologies, the company delivered a spectacular performance on the international stage of mining and metallurgy, successfully concluding its overseas exhibition tour.
01 Core Technologies Unveiled: Covering the Full Spectrum of Mining and Metallurgy Scenarios
At the exhibition, drawing upon its integrated "adsorption + membrane" technology, Haipu presented a suite of mature and practical separation and purification solutions tailored to key application scenarios—including the efficient extraction and purification of lithium resources; the enrichment and recovery of precious metals such as gold, silver, platinum, and palladium; the high-efficiency extraction of nickel from laterite ores; the selective separation of copper and molybdenum; the recovery and comprehensive utilization of rhenium via tungstic acid extraction in pyrometallurgical copper refining; the resource utilization of mine tailings; the near-zero discharge of mine wastewater; and the deep removal of residual extractants.
Enrichment and Extraction of Rare and Precious Metals：Selective adsorption resins for gold, silver, platinum, and palladium—as well as specialized resins for rhenium extraction—are widely utilized in complex systems, such as waste acids and cyanide leachates, to achieve the highly efficient recovery of low-concentration precious metals.
High-Efficiency Nickel Extraction from Laterite Ores：This process employs specialized adsorption resins to selectively enrich and deeply purify nickel ions present in the leachate of low-grade laterite ores, thereby effectively separating impurities such as iron and magnesium. Subsequently, homogeneous ion-exchange membrane electrodialysis is utilized to concentrate the nickel salts, significantly enhancing both the nickel recovery rate and product purity, while simultaneously reducing energy consumption during the subsequent evaporation and crystallization stages.
Selective Separation of Copper and Molybdenum: Customized chelating resins enable the highly selective adsorption and separation of copper and molybdenum ions, thereby avoiding the issues of emulsification and entrainment associated with traditional extraction methods. By integrating homogeneous ion-exchange membrane electrodialysis technology to further purify and concentrate the separated solution, high-purity copper and molybdenum products are obtained.
Rhenium Recovery and Comprehensive Utilization from Pyrometallurgical Copper Smelting Waste Acid: A specialized resin is employed to selectively adsorb the trace metal rhenium from the waste acid solution generated during pyrometallurgical copper smelting. Following elution and enrichment, high-purity rhenium products are produced, achieving industry-leading recovery rates. Furthermore, the process enables the removal of pollutant elements—such as arsenic, cadmium, and lead—that are abundant in the waste acid, thereby further reducing pollutant emission levels.
Tailings Resource Utilization: This process employs resins to selectively extract residual valuable metals (such as nickel, cobalt, and copper) from tailings. Following deep enrichment, ion membrane technology is utilized to concentrate and recover water resources and salts. This approach achieves the reduction and detoxification of tailings while enabling the recycling of valuable components, thereby facilitating green mine closure and sustainable development.
Near-Zero Discharge of Mine Wastewater: Utilizing technologies for heavy metal removal (arsenic, cadmium, lead), fluoride removal, COD reduction, oil removal, and advanced resin-based softening—integrated with electrodialysis concentration and bipolar membrane technology for acid and alkali production from salts—this solution drives mine wastewater toward near-zero discharge while enabling the high-value utilization of salt resources.
Comprehensive Solution for Lithium Extraction from Salt Lakes: Featuring fifth-generation aluminum-based and third-generation titanium-based lithium adsorbents—integrated with continuous ion exchange systems and bipolar membrane electrodialysis equipment—this solution is applicable to a wide range of brine scenarios, including those characterized by high magnesium-to-lithium ratios, carbonate compositions, and low grades; furthermore, it has already achieved industrialized application in numerous projects both domestically and internationally.
02 On-Site Report: High Energy, In-Depth Exchange
Throughout the exhibition, Booth No. 30—hosted by Haipu—enjoyed consistently high popularity, attracting mining enterprises and industry experts from regions including Australia, Southeast Asia, Africa, and South America, who frequently stopped by to engage in discussions. The on-site team held in-depth conversations with international visitors regarding technology implementation, project collaboration, and customized solutions; numerous clients expressed high commendation for Haipu’s integrated service capabilities—encompassing "materials + processes + equipment"—as well as its tailored separation and purification solutions. Furthermore, after learning about the performance parameters and industrial application case studies of Haipu’s high-performance adsorbents, several clients expressed their admiration for the products' stable performance under extreme operating conditions.
During recent exchanges, numerous international experts noted that the global mining industry is currently accelerating its transition toward low-carbon operations and efficient resource utilization. Consequently, there is an increasingly urgent demand among enterprises for technologies enabling the selective extraction of valuable metals from complex ores, the recovery of associated resources, and the achievement of near-zero wastewater discharge. Leveraging core technologies—including highly selective adsorption resins, homogeneous ion-exchange membranes, electrodialysis, and bipolar membrane electrolysis for acid-base production from salts—Haipu has developed a comprehensive "adsorption + membrane" process solution that aligns perfectly with the industry's trajectory toward green development.
HEPU remains steadfastly focused on the R&D and engineering of high-performance adsorption materials and separation processes, possessing comprehensive service capabilities ranging from laboratory validation to full-scale industrial implementation. After gaining an in-depth understanding of the stable performance of HEPU’s products under complex operating conditions—as well as the company’s capabilities in customized development—several clients expressed their intent to pursue future collaborations; consequently, the HEPU team has successfully secured promising international business opportunities.
Although the Perth rendezvous has drawn to a close, Haipu’s journey of global innovation and service never ceases.
Moving forward, Haipu New Materials will continue to drive technological advancement through materials innovation. Guided by the vision of "becoming a globally trusted scientific company for novel purification materials," and driven by the mission to "catalyze technological breakthroughs in the energy and resource sectors through materials innovation, bridge industrial value, and co-create a better life," the company will continuously optimize its core products and solutions for the comprehensive separation and purification of mineral resources. By deepening its focus on the field of green mining and metallurgy, Haipu New Materials will collaborate with global partners to jointly promote the low-carbon transition of the mining industry and the efficient circular utilization of resources.
Amidst the global megatrend of mining industry transformation, Haipu stands ready to engage in deep collaboration with an ever-expanding network of international partners. By leveraging cutting-edge adsorption and membrane separation technologies to empower green mining and metallurgy, we aim to continuously drive the high-quality development of the global mining and metallurgical sector.
