Core Viewpoint - A research team led by Pan Bo from Kunming University of Science and Technology has made significant breakthroughs in the resource utilization of solid waste red mud, developing a technology system supported by several core patents, which could provide a new "Chinese solution" to the environmental challenges posed by red mud in the global aluminum industry [1][2]. Group 1: Technology Development - The team has created a "green, efficient, and high-value" technology system over ten years, which includes a patented method for gently extracting iron from red mud and precisely preparing β-type hydroxy iron oxide [1][2]. - The technology not only maximizes the utilization of solid waste but also transforms it into valuable resources, addressing the global challenge of red mud management [1]. Group 2: Environmental and Economic Impact - The extracted aluminum-silicon residue from red mud can be synergistically treated with other bulk solid wastes like fly ash and coal gangue to produce multi-level porous functional ceramic particles, which have applications in construction materials and water treatment [2]. - This innovative technology achieves both environmental and economic benefits, addressing the pain points of red mud management while also providing a solution for other solid waste types [2]. Group 3: Market Potential and Collaboration - The technology has completed comprehensive laboratory validation and is ready for pilot-scale expansion and industrial demonstration, showcasing high product added value, strong solid waste synergy, high resource utilization, and environmental friendliness [2]. - The research team is actively seeking partnerships with large aluminum, energy, and environmental companies to establish pilot demonstration lines and industrial production bases, aiming to contribute to China's green low-carbon development and ecological civilization [2].
