Speaker
Miss Jaishree Yadav
PhD student
RMIT University
Selective leaching of rare earth elements from NdFeB magnet waste using salt solution
10:35 AM - 10:55 AMBiography
Jaishree Yadav is currently pursuing her Ph.D. at RMIT University in collaboration with the Commonwealth Scientific and Industrial Research Organisation (CSIRO), Australia, having commenced her candidature in 2024. Her research is primarily focused on the optimization of sustainable hydrometallurgical processes for the efficient recovery of rare earth elements from end-of-life NdFeB permanent magnet. By employing innovative selective leaching and separation techniques, her work aims to achieve high recovery rates while minimising the co-extraction of impurities, thereby enhancing process sustainability and economic viability. Ultimately, her research contributes to advancing circular economy practices and securing a stable supply of these critical materials for emerging clean energy and high-tech applications.
Mr Quang Thinh Tran
PhD candidate
Curtin University - Perth
Upgrading rare earth from clay deposits in Western Australia: Mineralogical controls via physical and thermochemical treatments
10:55 AM - 11:15 AMBiography
I am a PhD candidate at Curtin University (C3MET group), currently in my final year of my PhD. My thesis focuses on the downstream processing of rare earth elements from abundant clay minerals in Australia.
Dr Hongli Su
Postdoc
Delft University of Technology
Optical sorting for coarse REE pre-concentration by ink-coating and magnetic lifting
11:15 AM - 11:35 AMBiography
Hongli Su is a researcher in mineral processing and resource recovery at TU Delft, with expertise in sensor-based sorting, magnetic density separation, and process design for complex particulate materials. His work focuses on the beneficiation of critical mineral ores and the development of innovative separation strategies for fine particles in the millimetre size range. He has contributed to optical sorting systems for rare earth ores and other heterogeneous mineral feeds, combining experimental work, process optimization, and scale-up considerations. His broader research interests include sustainable mineral beneficiation, intelligent separation systems, and the integration of novel sorting technologies into future resource-efficient processing flowsheets. Through his work, he aims to advance both the fundamental understanding and practical application of next-generation mineral separation technologies for critical raw materials and circular resource use.
Mr Ren Tao
Doctoral student
Royal Institute of Technology
Thermal pretreatment for selective recovery of rare earth elements from permanent magnet waste
11:35 AM - 11:55 AMBiography
Ren Tao is a PhD student in the Division of Resource Recovery at KTH Royal Institute of Technology, focusing on the recovery of valuable metals from waste permanent magnets. His research explores green solvent leaching and anti-solvent crystallization to develop efficient and sustainable metal extraction and recycling processes.
Mr Rakesh Velpoor
PhD student
Swinburne University of Technology
Effect of low temperature alkaline treatment on the oxidation of end-of-life NdFeB
11:55 AM - 12:15 PMBiography
Mr Rakesh Velpoor completed his Master's in Materials Engineering at IIT Roorkee and holds a Bachelor's in Mechanical Engineering from Vasavi College of Engineering, Hyderabad. Previously, Rakesh was an engineer at Tata Advanced Systems Ltd. He is currently a PhD student at Swinburne University of Technology, where he is developing a new recycling process to recover rare earth elements from scrap magnets. His research interests include Li-ion battery and magnet recycling for critical metal recovery.
