Malik Nausherwan Ali Saggu is a third-year PhD student at the Centre for Advanced Materials and Industrial Chemistry (CAMIC), School of Science, RMIT University, Australia. His research focuses on the sustainable processing of nickel laterite ores. In collaboration with QPM Energy, he investigates hydrothermal iron removal in nitric acid–based metallurgical flowsheets to improve process efficiency and reduce waste. His work integrates advanced materials characterisation with reaction engineering to generate process-relevant insights, supporting the development of sustainable and industrially viable processing technologies for critical minerals processing.

Xuhui Zhu is a PhD candidate in the Department of Chemical Engineering at the University of Melbourne, supervised by Dr. Helena Wang in the Renewable Resources & Sustainability (R2S) group. She obtained her Master’s degree from Jiangsu Normal University in 2024, where she conducted research under the supervision of Prof. Shun Yang. Her current research focuses on the recycling and regeneration of cathode materials from spent lithium-ion batteries, including the application of deep eutectic solvents and rapid thermal processes.

George Franks is Professor in Chemical Engineering at the University of Melbourne. His degrees are in Materials Science and Engineering (Bachelor MIT, 1985, PhD UCSB, 1997).

Dr Wen Li is a Research Fellow in the Advanced Separations Group at University of Melbourne. Her research focuses on the recovery and purification of critical metals and bioactive compounds using advanced separation technologies, particularly solvent extraction. She received her Master’s degree in Materials Engineering from the University of British Columbia and completed her PhD at University of Melbourne, where she worked on pulse solvent extraction column design and modelling. Dr Li collaborates extensively with industry partners and worked on several ARC hubs and projects for developing industrial processes, process models and techno economic analysis and designing large scale reactors.

Jack Walsh is a PhD candidate at the University of Adelaide, where he is researching the recovery of ultrafine graphite for battery anode use. He has site experience at Sibanye Stillwater’s Century Operation and BHP Carrapateena. His area of interest is in critical mineral recovery, particulary in the energy- and cost-efficient recovery of textured ores.

Tareq is a PhD student in the Chemical Engineering Department at the University of Melbourne. His current research focuses on understanding bubble-particle and bubble-aggregate interaction at the microscale using CFD-DEM simulations to improve recovery of fine particles in froth flotation. Previously, Tareq used CFD to simulate the release of a trapped oil blob in a constricted capillary tube under external excitation for enhanced oil recovery purposes. He also investigated the in-situ stresses orientation change resulting from gas production in shale gas reservoirs by coupling fluid flow in porous media with geomechanics using FEM simulations.
