Brief description Reverse engineering nature: metal extraction through mineral replacement. This project aims to find new methods of copper recovery from low grade copper ores, which are currently uneconomic to mine. In nature, at the top of ore deposits and just below the water-table, is a region known as the supergene zone. Here mild oxidizing reactions take place causing primary ore minerals such as chalcopyrite to be replaced by more copper-rich, less refractory minerals. These processes are driven by dissolution re-precipitation reactions (CDR reactions) and in many CDR reactions, the reaction mechanism, rather than intensive properties such as pressure and temperature, control the nature of the products and the overall reaction process. This project will explore the mechanism and controls on these reactions to see if they can be utilized in the mining industry to economically extract copper from low grade ores.\n\n
