Prof Aubrey Mainza 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 (specializing 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 in 2007 he took up the role of Head of Comminution Research in the Centre for Minerals Research. In 2008 Aubrey was appointed as Senior Lecturer and took an active role in undergraduate teaching core Chemical Engineering and Minerals Elective Courses within the Department of Chemical Engineering. Aubrey become an Associate Professor in 2013 and a Professor at the beginning of 2016. Aubrey is the currently the Deputy Director and Heads of Comminution research for the CMR, and participates extensively in collaborative research with international universities, mining companies, and comminution and classification equipment manufacturers.
