Professor Fanus Viljoen holds an MSc from the University of Cape Town and a PhD from the University of the Witwatersrand, both in Geochemistry. Having been involved in the study of kimberlites, diamonds and mantle xenoliths for much of his career while employed in Industry, he joined the University of Johannesburg in 2008 to take up the DST/NRF Research Chair in Geometallurgy. Geometallurgy is a rapidly evolving field of interdisciplinary research that bridges the gap between the geosciences, minerals research, metallurgy and the mining and exploration industry. The primary thrust of the Research Chair is to develop and apply geometallurgical methods to quantify the mineralogical and textural characteristics of ore bodies, ores, concentrates and successor products in resource types relevant to the South African minerals industry. Professor Viljoen is the author and co-author of 54 articles in peer-reviewed journals as well as numerous congress proceedings abstracts.
