The mining and metals industry is facing the need to develop novel technology that addresses the requirements for sustainability in the extraction and processing of natural mineral resources. The Aqueous Process Engineering and Chemistry (APEC) group is providing solutions in the processing of complex mineral resources by studying the fundamentals of aqueous process chemistry and engineering to recover and produce metals or metallic products by hydrometallurgical routes. The research focuses on developing novel chemical processing ideas to:
