Dee Bradshaw is the UCT hosted South African Research Chair: Mineral Beneficiation at the University of Cape Town (UCT) and the Director of UCT’s Minerals to Metals Signature Theme. She is also an Honorary Professor at the Sustainable Minerals Institute at The University of Queensland (UQ). Her focus in on ‘adding value’ from minerals resources by developing technical levers that incorporate sustainability principles to contribute to the provision of minerals and metals to a sustainable world. With over 30 years of experience, Dee’s background is in Flotation Chemistry and Process Mineralogy with her interests expanding into other aspects of the field as she continues to work towards the ‘Development of an Integrated Mineralogical Framework for Mineral Processing from ore deposit, through breakage and separation, including the effects of texture on liberation, of valuable from unwanted minerals to disposal of waste and tailings’ (first articulated in 2005). She has been responsible for initiating, setting up and participating in post graduate courses in flotation chemistry, process mineralogy, geometallurgy and building research capacity in general at the UCT, UQ, U of Tasmania and HU. She has participated in JKTech’s MetSkills program for Metallurgical Training as well as many professional development courses for industry in South Africa, Australia, Canada and Turkey. This includes her participation as a visiting scholar (2014/ 2015) for the European Master in Georesources Engineering in activities at the University of Liege, Belgium and the Lulea Technical University, Sweden. She delivered a 2 day course ‘Sustainability in mining’ in Oct 2014 at the Universidad Católica del Norte, Antofagasta Chile.She has supervised over 40 post graduate research students and co-authored over 150 journal and conference papers. In 2013 she was recognised by the University of Queensland as a leader who nurtures and develops her graduate students, a concept she calls ‘Living Gold’ (‎)

Research Interests

From a career that focused on the flotation process and interactions at mineral/water/air interfaces, focus has evolved towards understanding the interactions that occur at the society/technology/policy interfaces. The development of ‘T’ shaped professionals that can contribute technical depth as well as breadth by working in interdisciplinary teams. This will build future leadership capacity through education, research and engagement and international communities of practice and contribute to the sustainability of the provision of minerals and metals to the world.
