Technical Executive in Mine Tailings at WSP Australia with over 20 years of experience in geotechnical engineering applied to civil and mining projects. Mavi is a highly experienced specialist in tailings and dam engineering, with a strong background in site characterization, stability analysis, and advanced numerical modelling, including liquefaction susceptibility assessments of mine waste facilities. She holds a Ph.D. and M.A.Sc. in Geotechnical Engineering from the University of British Columbia (UBC), where her research focused on the mechanical characterization of natural low-plasticity silts and tailings. Her career includes extensive involvement in both in situ and laboratory investigation programs, with a particular emphasis on advanced testing and interpretation for tailings dams and foundation systems. Mavi contributed to major mining projects across Canada, Chile, Peru, and the United States. Her experience spans the full project lifecycle, including site investigation, design, construction support, and performance assessment of dams and tailings storage facilities. She is also actively involved in advanced geotechnical laboratory practice, serving as a subject matter expert and reviewer for specialized testing programs supporting both academic research and industry applications. Earlier in her career, she worked as a Research Assistant at UBC and as a Project Engineer in Colombia, building a strong foundation in both research and applied geotechnics. Mavi is a registered Professional Engineer with Engineers and Geoscientists of British Columbia (EGBC), as well as with the Northwest Territories and Nunavut Association of Professional Engineers and Geoscientists (NAPEG) and Professional Engineers Ontario (PEO).

Kevin Galvin is the inventor of the Reflux Classifier used in gravity separation of fine mineral particles. With over 240 installations around the world, the technology has been used to beneficiate iron ore, mineral sands, metallurgical coal, potash, chromite, lithium, tantalum, cassiterite and other base metal oxides. New innovative systems are emerging including the Reflux Flotation Cell, Graviton, GradePRO, and a novel agglomeration technology. Kevin Galvin is a Laureate Professor at the University of Newcastle, Australia. He is a Fellow of the Australian Academy of Science and Australian Academy of Technology and Engineering and previous recipient of numerous awards including the Ian Wark Medal, ATSE Clunies Ross Award, and Antoine Gaudin Award in mineral processing. He is Director of the ARC Centre of Excellence for Enabling Eco-Efficient Beneficiation of Minerals.

John is a minerals process engineer with a background in chemical and metallurgical engineering. His experience and contributions in his current role are primarily in the space of comminution, developing various power-based throughput forecast and crushing & grinding circuit models.

Johan has been working in the minerals processing industry for the last 20 years. His experience includes PGM and Iron ore processing, with a key focus on feed characterisation and process optimisation. He spent the first 6 years of his career focusing on platinum processing in South Africa; then he transitioned to Iron Ore in 2011 by joining Onesteel in Whyalla. During the last 14 years he has supported several hematite and magnetite projects from feed characterisation stage to final commissioning stages of the processing plant. He has been part of the minerals processing team at Hatch for the last 6 years and continued his passion for understanding feed and finding ways to produce cost effective products for his clients.

Nichole Maistry is a senior engineer at Mintek in the Mineral Processing Department. She obtained her MSc Engineering in Metallurgy and Materials from the University of the Witwatersrand, as well as a National Certificate in management from Duke Corporate Education.
