About Prof Bertus Smith
Bertus Smith is currently specializing in Economic Geology with a focus on sedimentary iron and manganese deposits. Other research interests include Archaean and Palaeoproterozoic sedimentary successions and Geometallurgy, which is the quantification of the variability of ore deposits in terms of processing behaviour (blasting, crushing, milling, liberation and recovery). He is also affiliated with the DST-NRF Centre of Excellence for Integrated Mineral and Energy Resource Analysis (CIMERA) as well as the PPM Research Group, both based at the Department of Geology at the University of Johannesburg. He completed his PhD in Geology at UJ in 2014, which focused on Geometallurgy of the Merensky Reef at Bafokeng Rasimone Platinum Mine. He completed his MSc in 2007 on the banded iron formations and iron-rich mudstones of the Witwatersrand and Pongola Supergroups at UJ, for which he received the Chancellors Medal for most meritorious MSc thesis in the Faculty of Science, as well as the Corstorphine Medal and Johan Handley Prize from the Geological Society of South Africa. He also received the award for best student speaker at the Society for Economic Geology Student Geocongress for a presentation on his MSc work in 2008.
