Overview
Background
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.

Research impacts
I am an exceptional Geometallurgical (Geochemistry plus Hydrometallurgy) engineer and applied scientist with a well-rounded skillset and a passion for innovation. My academic excellence, diverse industry experience, and dedication to data-driven solutions make me a valuable asset to the Australian critical minerals industry. I bring over ten (10) years of comprehensive experience in the resources sector, having worked as a hydrometallurgist and chemical engineer for industry leaders like Northern Star Resources, Shell, Goldfields, and AngloGold Ashanti accross Australia and Africa. Further I have a proven track record in developing innovative leaching technology for sustainable metal extraction and mine waste reclamation as part of the BHP’s Think & Act Differently (TAD) Essential Minerals Cohort. Additionally, I have worked with top artificial intelligence (AI) start-ups such as Funartech and as a patent intern in the Chemistry group at Davies Collins Cave (DCC). Overall, I am passionate about driving sustainable solutions in the critical minerals and energy industries. I possess a deep understanding of circular economy innovations for the extraction of critical green metals from mine waste and low-grade mineral ores; valorisation and transformation of mine waste into useful end-products; carbon storage in mine waste, processing and refining of critical minerals and data-driven decision-making relevant to transitioning Australia to a net zero low carbon-based economy.
