Dr Richmond K. Asamoah is a Senior Research Fellow at the Future Industries Institute (University of South Australia) with over twelve years in-depth knowledge of and hands-on experience in mineral processing and extractive metallurgy in tandem with surface, interfacial and data science. Richmond holds BSc (Hons) Minerals Engineering and PhD Engineering (Minerals and Resources), obtained from the University of Mines and Technology and University of South Australia, respectively. His research interests are in physical separation and beneficiation of complex mineral ores (low grades and wastes), hydrometallurgy (including bio-), and machine learning and data analytics, having links with environmental sustainability.
Richmond currently conducts research as part of the Australia-India Strategic Research Fund (AISRF; funded by the Department of Industry Science and Resources, Australian Government) for advanced recovery of the battery materials and rare earth elements from ores and wastes, and Premier’s Research and Industry Fund Research Consortia Program (PRIF RCP, funded by the Department of Innovation and Skills, SA Government) for unlocking complex resources through lean processing. He is also an Associate Investigator of ARC Centre of Excellence for Enabling Eco-Efficient Beneficiation of Minerals. Visit research website for more details. Previously, Richmond supported South Australian small and medium-sized companies in addressing business-critical and pressing problems or issues through the Future Industries Accelerator (A 7.5 million investment from the South Australian State Government). He is regularly consulted by industry in his field of research.
