This type of technology can be applied in the recovery of base metals such as coper, nickel, cobalt, etc and in the environmental area for the clean up of heavy metals from waste water. Solvent extraction has the advantage of high selectivity that enables metals to be recovered and recycled, thus reducing the wastage of these metals in, for example, the chromium plating process.Read moreRead less
Tetconic feedback and the long-term evolution of the continents. The continents are shaped through complex interactions between the primary tectonic processes of magmatism, metamorphism, deformation, erosion and sedimentation. Because these processes modify the distribution of heat producing elements, and are themselves temperature sensitive, they must be subject to important feedback loops. This project will use constraints on heat producing element distributions in the Australian crust, and th ....Tetconic feedback and the long-term evolution of the continents. The continents are shaped through complex interactions between the primary tectonic processes of magmatism, metamorphism, deformation, erosion and sedimentation. Because these processes modify the distribution of heat producing elements, and are themselves temperature sensitive, they must be subject to important feedback loops. This project will use constraints on heat producing element distributions in the Australian crust, and the way in which these distributions have evolved during various tectonic processes, to elucidate the nature and significance of "tectonic feedback" and its role in shaping the continents.Read moreRead less

This project involves a fundamental study of the kinetics of reactions that occur in solvent extraction processes used for separation of many of Australia's metals from minerals. The understanding gained from this will enable a greater efficiency to be obtained from Australia's minerals industry. In particular, it is intended to investigate the role of additives on the kinetics of metal extraction; these additives either enter the solution from the ore or are added as flocculants during the process, and have a significant effect on the performance. With the move to smaller, shorter residence time contactors, this has become increasingly important if these new contactors are to be used efficiently.Read moreRead less
