Yongjun Peng

Professor Yongjun Peng is a Professor at the School of Chemical Engineering, University of Queensland. He holds a PhD from the University of South Australia (2002) and has expertise in froth flotation, mineral processing chemistry, and electrochemistry. His research focuses on optimizing low-quality mineral processing using saline water and addressing challenges in particle interactions, slime coating, and froth destabilization.

• Key appointments: COREM Research Centre (Canada, 2002–2006), BHP Billiton Perth Technology Centre (2006–2009)
• Technologies commercialized: GoldRecover (Kinetic Group), de-aerating froth products (DADI Engineering), rapid coal oxidation measurement (Interchem)

His research interests include galvanic interactions in grinding, sulfidization processes for oxidized ores, and green flotation chemistry using biopolymers. Peng has developed patented technologies to improve flotation recovery rates and reduce reagent consumption. He leads projects funded by ARC, ACARP, and industry partners like Newmont and Newcrest.

Major awards include the ACARP Research Excellence Award (2022) and NSERC Industry Fellowship. He actively supervises PhD and Master’s students focusing on froth dynamics, reagent interactions, and particle behavior in flotation systems.
