Dr Liza Forbes specialises in mineral flotation with specific focus on flotation reagent chemistry, mineral surface chemistry and base-metal sulphide electrochemistry.

Her main interest lies in integrating fundamental and applied aspects of flotation research, to develop new and improved processing technologies.

Education and Work

Liza graduated with a PhD in Chemical Engineering from the University of Cape Town in 2007. Since then, she has worked at the N.B.Keevil Mining Institute, University of British Columbia; the Department of Chemical and Biomolecular Engineering, University of Melbourne; and CSIRO Mineral Resources.


Liza has previously worked at a metallurgist at the Bafokeng Rasimone Platinum Mine, Anglo Platinum in South Africa. She has since been involved with a number of industry research projects with companies such as Kennecott Copper Co, Zijin Mining, Newmont, Newcrest, Sytec Technology Solutions and Anglo Coal.
