Lev Filippov is Full Professor at the National Engineering School of Geology where he was responsible for the "Mineral raw materials" department. With over 40 years of experience in mineral processing research he is author of more than 280 peer reviewed and conference papers. He authored and co-authored 22 international patent applications. The main research areas cover the fundamental and applied researches on the flotation recovery of the strategic metals from primary (ores) and secondary resources.

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.

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 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.
