Dr. Eric O. Ansah is a postdoctoral research fellow at the W.H. Bryan Mining Geology Research Centre, Sustainable Minerals Institute at the University of Queensland. He is currently researching sustainable solution that addresses both improved metal extraction and the potential to improve mine closure outcomes. Eric has expertise in Geochemistry and Hydrometallurgy with proven track record in developing innovative heap leaching technology for sustainable metal extraction and mine waste reclamation as part of the BHP’s Think & Act Differently (TAD) Essential Minerals Cohort. The protonated brine lixiviant technology was developed as part of his PhD studies into coupled chalcopyrite dissolution with reprecipitation during copper heap leaching at the University of Melbourne.He has worked in metallurgical and geochemical research, plant operations, translation of research to industrial start-up and technology development. Some of his projects and studies involved copper, gold, silver, cobalt, uranium, and REE.
