Biohydrometallurgy for the extraction of value from primary and secondary mineral resources and waste streams. EU BIORECOVER: Development of an innovative sustainable strategy for selective biorecovery of critical raw materials from Primary and Secondary resources. Sustainable mineral resource development: Impact of post-mining transformation strategies on the WEF nexus.
My main research activities focus on elucidating the fundamental mechanisms that govern mineral-microbe interactions in heap bioleaching systems. Aside from developing novel approaches to simulate these large-scale operations in the laboratory, I am focussed on developing mathematical models to describe these mineral-microbe interactions, with the aim of providing insight as to how the leaching process may be improved. I am keen to draw on this knowledge and apply it the prevention and mitigation of pollution from mine waste streams, since the same mechanisms govern acid rock drainage (ARD) generation and lead to toxic metal deportment. The knowledge gained from bioleaching of mineral sulphides is applied to the extraction of valuable metals from printed circuit and cable waste. The ewaste associated projects focus on quantifying metal leaching kinetics and modelling the performance of various reactor configurations with the aim of developing process flowsheets for the extraction and recovery of economic value from waste streams that are scalable for application in SMMEs. I am also involved in research projects that consider the social and environmental impact of mining activities in South Africa on land use and natural water resources. Specifically, the research focuses on understanding the impact of post-mining transformation strategies on the water-energy-food nexus.
