Christian Wilke is a Ph.D. student at the Institute of Mechanical Process Engineering and Mineral Processing of the Freiberg University of Mining and Technology, Germany. He has worked for 7 years as a senior process engineer for the Kleemann GmbH (part of the Wirtgen Group) focusing on the application of mobile crushers and screens in quarries worldwide. Christian holds a master degree in Waste Management from the RWTH Aachen University and completed the European Engineering Course (EMEC) of the Federation of European Mineral Programs (FEMP) at the Camborne School of Mines (UK), the Politechnika Wroclawska (Poland) and the Aalto University (Finland). Currently he is concentrating on the mechanical recycling of lithium-ion batteries with a focus on the thermal pre-treatment and its influence on the sorting and classification processes.

Junnan Lu is currently a PhD candidate under the supervision of A/Prof. Kathryn Mumford and Prof. Geoff Stevens at The University of Melbourne. His current research interests sit in the application of solvent extraction in spent lithium-ion batteries recycling industries. His research focuses on the experimental feasibility study, thermodynamical modelling and process technic, economic and environmental assessments.

Xianbo Li, Male, Doctor, Master Supervisor, Teacher of Guizhou University. The main research direction is beneficiation of refractory ores and comprehensive utilization of resources. I host two scientific research projects about phosphogypsum at present, and I have published more than 20 academic papers in domestic and foreign journals. Among them, 8 SCI papers were published asthe first author. Besides, I published a monograph《Preparation and properties of α-hemihydrate phosphogypsum》.

After completing a Bachelor's degree in Nanotechnology at Curtin in 2006, I became part of the Chemistry Department's Nanochemistry Research Institute to conduct my Ph.D. into the influence of soluble silicates on iron precipitation from zinc solutions. In December 2010 I joined the Materials Engineering Department at the University of British Columbia in Vancouver for an invaluable 2-year Postdoctoral Fellowship. This led to my current position with Curtin in Kalgoorlie in July, 2013 upon returning to Australia.

Jane Thorne joined Geoscience Australia in October 2012 after completing a degree at the Australian National University in Canberra. She has worked as a Project Geologist on a range of national to regional scale mineral system studies and data releases for the Australian Government. She is currently leading the National Mine Waste Assessment Project for Geoscience Australia’s Exploring for the Future program.

Christina works within the Chalmers Rock Processing Systems (CRPS) research group. Coming from a Masters in Environmental Science at Gothenburg University, she brings an interdisciplinary element to the group with a key interest in the environmental impacts related to the aggregate industry. Her current research focuses on the integration of environmental management into operational improvements for the industry and is exploring the potential for digitalization in the field. The goal is to aid producers in calculating and improving their environmental performance.

Mr. Khairul is a PhD student at RMIT University, Melbourne in a collaboration with CSIRO Mineral Resources. Prior to that, he has completed a Masters and Bachelor in Materials and Metallurgical Engineering from the Bangladesh University of Engineering and Technology. Khairul has experience of working 7 years in academia and research organisations. He has been working as a research engineer in Bangladesh Council of Scientific and Industrial Research (BCSIR) since 2015 where he does scientific research and provide technical support to industry and govt. agencies to solve problems and take scientific decisions. He also worked as a visiting scientist in CSIRO with an Endeavour Executive Fellowship of Australian govt. in 2018. His current research focuses on the slag system and phase equilibria to recover valuable metals from e-waste using pyrometallurgical route.

Dolf has nearly 50 years of mineral processing experience in operations, consulting and mineral processing equipment development along with management experience both at operations and project specific levels. He has been involved with projects in the hydrocarbons, minerals, metals and chemical industries. His experience covers, sulphur handling, chemicals, bulk materials handling, base metals (including froth flotation and smelting), iron ore, mineral sands, chromite, bauxite/alumina, coal and industrial minerals specifically in the development of mineral processing flowsheets, process improvement and auditing and establishment of circuit performance guarantees and testing. He has operational experience in comminution, heavy media separation, froth flotation, and smelting. His experience spans the globe with involvement in major projects in most parts of the world, including Australia, Africa, Canada, North and South America, Europe, Asia, India, Saudi Arabia and New Zealand.
