Kevin Galvin is the inventor of the REFLUX(TM) Classifier used in gravity separation of fine particles. With over 170 installations around the world, the technology has been used to beneficiate coal, iron ore, mineral sands, potash, chromite, and other base metal oxides. He is also the inventor of the REFLUX(TM) Flotation Cell, a new flotation technology which is the subject of this presentation. Kevin Galvin obtained his PhD from Imperial College and 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 Antoine Gaudin Award in mineral processing. He is Director of the ARC Centre of Excellence for Enabling Eco-Efficient Beneficiation of Minerals.

Belinda McFadzean is an Associate Professor in the Centre for Minerals Research in Cape Town, South Africa. Her research focusses on the flotation process from fundamental molecular surface interactions to plant-scale optimisation techniques. Her particular interest is the interactions of surface-active reagents at air-water and solid-water interfaces and quantifying these effects on the froth behaviour in order to predict flotation performance.

Ms Dzinza is a PhD candidate within the Centre for Minerals Research at the University of Cape Town. She is currently employed as an Engineer in the Mineral Processing Division at Mintek. She completed her undergraduate degree in Chemical Technology from Midlands State University, Zimbabwe. She joined the CMR for an MSc, graduating in 2018. Her PhD considers the electrochemistry of minerals systems, with a special focus on the impact of water quality within flotation.

Tim Walsh is an Applications and Development Chemist with Clariant Oil and Mining Services, where he performs research and development of froth flotation chemicals. He has 20 years experience in diverse fields including explosives, fertilizers, plastics, analytical chemistry, enzyme chemistry and mining. Tim holds a BSc. (Hons) from The University of Melbourne and MSc. from Deakin University.

Sophia graduated with a BSc Honours Degree in Metallurgy from the University of Zimbabwe. She then studied for a Master of Science in Engineering Degree: Metallurgy and Materials, with the University of the Witwatersrand. She is currently studying for a PhD in Chemical Engineering, at the University of Cape Town, and is employed as an Engineer at Mintek. Her research seeks to understand the reasons for the poor floatability of sperrylite (PtAs₂) and to improve its flotation recovery.

Sancho is a dynamic young researcher in mineral processing with an interest in both physical and physicochemical separation methods and the role of water in them. His experience is primarily with coal and base metal sulfides, and he has published on the former. He holds a BSc (Hon.) in Applied Chemistry and an MSc in Metallurgy and Materials Engineering. Currently, he is a PhD student in the Centre for Minerals Research at the University of Cape Town. When asked about his primary motivation, he responds, ‘It’s simple. If a resource is finite, it needs a wise and knowledgeable steward to handle it. That’s what l want to be in the minerals industry.”

Mr. Moonchul Jung is currently a Ph.D. candidate at Western Australian School of Mines, Curtin University. He holds B.Sc. and M.Sc degree in Energy Resources Engineering at Korea Maritime and Ocean University, majored in mineral processing engineering and hydrometallurgy for his master. After graduation in 2018, he joined the Korean Institute of Geoscience and Mineral Resources for a year as an intern researcher and participated in the research project investigating the caustic leaching behavior of ilmenite to produce high-grade rutile. His current research interest is the effects of water quality on rare earth phosphate minerals.
