Summary

Dr Hong Peng presents a seminar on a paradigm shift in resource recovery, focusing on turning impurities from mine waste into saleable products. He introduces his research background and the Sustainable Extraction Engineering Laboratory at UQ. The core of his work involves manipulating iron, aluminum, and silicon chemistry to separate and recover valuable metals. He details five industry-driven projects: Mud2Products (bauxite residue utilization), Clay2Products (high-purity zeolites and rare earth extraction), Slag2Products (titanium-bearing steel slag), Invisible Gold Recovery (manipulating iron precipitation for refractory gold sulfides), and Cavern Salt Recovery (potassium extraction from basin boree salt). The projects range from bench scale to pilot plant, demonstrating technology readiness levels up to 7. He emphasizes the importance of understanding solution chemistry and phase diagrams to control processes. The seminar concludes with acknowledgments and a Q&A session.
