Speaker
Malik Nausherwan Ali Saggu
PhD Student Of Applied Chemistry
RMIT University
Towards Sustainable Nickel Laterite Processing: Optimising Hydrothermal Iron Removal under Industrial Conditions
1:30 PM - 1:45 PM
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
Phd Candidate
The University of Melbourne
Rapid Selective Recycling of Spent LiFePO4 Cathodes via a Deep Eutectic Solvent-Assisted Carbothermal Shock Method
1:45 PM - 2:00 PM

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 Michael Walsh
Phd Candidate
Adelaide University
Novel Hydrodynamic and Chemical Approaches to Ultrafine Graphite Flotation
2:30 PM - 2:45 PM
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.
Mr Maksis Darzins
Phd Candidate
Monash University
Pilot Campaign Results of Direct Air Capture System: Investigating System Stability at Kilogram-Per-Day Scale
2:45 PM - 3:00 PM
Maksis Darzins is a post-graduate engineer with a passion for mechanical design and real-world problem solving.
He has a desire to use his skills to create a positive social and environmental impact. He graduated from Monash University with a double degree in Mechanical Engineer and Industrial Design which provided him the skills to continue into the Industry Doctorate Program.
