Associate Professor Belinda McFadzean
BSc UPE (2000), BSc Hons Chemistry cum laude UPE (2001), MSc Chemistry cum laude UPE (2003), PhD NMMU (2007)
Belinda McFadzean is an Associate Professor in the Centre for Minerals Research, University of Cape Town. Her research focusses on the flotation process and spans the spectrum 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 ultimately predict flotation performance. She manages large research projects, supervises a group of postgraduate students and has a growing publication record in the international mineral processing literature. She teaches postgraduate level courses to industry graduates and is a consultant to the mineral processing industry, including Anglo Platinum, Lonmin, Impala, Nkomati, Senmin and Vale.
