Qualifications
ND Food Technology (Cape Technikon) 1982
MSc Chemical Engineering (UCT) 2009

Background
Jenny Wiese is a Research Officer in the large, multidisciplinary Centre for Minerals (CMR) Research at the University of Cape Town. Her research focusses on the flotation process in mineral processing. Her particular interests are in the area of gangue management, froth phase behaviour and the impact of comminution environment on subsequent downstream processes with particular emphasis on flotation, and the impact of particle properties on flotation performance with emphasis on the influence of particle shape/morphology. She manages large research projects, both contract and applied, supervises a group of postgraduate students and supervises undergraduate students for their final year project, CHE4045Z. She manages the administration and annual budget for the Reagent Research Group (RRG) and is the CMR contact for the members of this group; Anglo Platinum, Impala Platinum and Lonmin Platinum.
