The keynote lecture "The growing trend of using high steel load in SAG mills – what is driving this?" was given by Prof. Aubrey Mainza, of the University of Cape Town.
Aubrey graduated with a Bachelor of Science (majoring in Metallurgy and Mineral Processing) from the University of Zambia in 1998. He completed his PhD in Mechanical Engineering (specialising in the areas of comminution and classification in mineral processing) at UCT in 2006. He joined the Centre for Minerals Research as a Research Officer in 2002, then became a Senior Research Officer, and is now a Senior Lecturer in the Centre.
Today Aubrey heads CMR's Comminution research, teaches core Chemical Engineering, and participates extensively in collaborative research with international universities, mining companies, and comminution and classification equipment manufacturers.
The keynote lecture "Taking ownership of our future: the case for cooperative research and technology development in the mining industry" was given by Prof. Malcolm Powell, of the University of Queensland, SMI-JKMRC and Liner Design Services, Australia.
Malcolm has applied fundamental comminution research to design and process improvement on over 60 mines worldwide during 30 years at Mintek, UCT, and the JKMRC. He has communicated his work in over 200 papers. He collaborates extensively, with close compatriots on 5 continents forming the Global Comminution Collaborative.
His professional objective is to maximise resource utilisation through significantly decreasing the energy and environmental footprint. to this end he leads three R&D companies and contributes to University research.
The keynote lecture "Modelling and optimization of wet and dry fine grinding processes" was given by Prof. Dr.-Ing. Arno Kwade, Director at TU Braunschweig.
After completing his doctorate on autogenous fine comminution in stirred media mills in 1996, Arno Kwade worked for 9 years as a process engineer in two leading positions in industry, firstly in the field of planning bulk solids handling equipment and secondly in the production of building materials.
Since 2005, he has headed the Institute for Particle Technology at the Technical University of Braunschweig, focusing on fine comminution and classification as well as bulk solids technology, bio- and pharmaceutical particle technology, and battery process technology.
Today, he heads the ProcessNet Competency Group Comminution and Classification as well as the Working Party Comminution and Classification of the European Federation of Chemical Engineering and is Vice-President of the Global Comminution Collaboration. His research focuses on gaining deeper knowledge and developing process-structure-property relationships as well as mechanistic models of processes in which particles are mechanically stressed and formulated.
