SYNCHROTRON MICROPROBE METALLURGICAL CASE STUDIES. The micro-focus capabilities of synchrotron techniques (XRF, XRD, XAS) will enable the high resolution spatial correlations required to advance the understanding of the three systems to be studied:
- Activation for flotation of sphalerite with varying iron contents;
- Arsenic leaching as a function of local structure, phase and mineral assemblage;
- Optimisation of ferrous alloy microstructure on cryogenic treatment.

- Activation for flotation of sphalerite with varying iron contents;
- Arsenic leaching as a function of local structure, phase and mineral assemblage;
- Optimisation of ferrous alloy microstructure on cryogenic treatment.
These case studies have been chosen to specifically target the minerals processing and manufacturing industrial sectors and will be used to increase industrial awareness of the potentials of synchrotron techniques prior to the commissioning of the Australian Synchrotron in 2007.

Managing Contaminant Metals in Complex Hydrometallurgical Processes; Meeting techno-economic, environmental and operability objectives. Sustainability of the minerals industry is predicated on being able to refine metals from increasingly lower-grade ores. This brings with it the critical problem of managing all contaminant elements present to ensure overall economic and environmental performance. Hydrometallurgical processes are favoured, though difficulties arise in controlling product charact ....Managing Contaminant Metals in Complex Hydrometallurgical Processes; Meeting techno-economic, environmental and operability objectives. Sustainability of the minerals industry is predicated on being able to refine metals from increasingly lower-grade ores. This brings with it the critical problem of managing all contaminant elements present to ensure overall economic and environmental performance. Hydrometallurgical processes are favoured, though difficulties arise in controlling product character to suit downstream processing. This project will develop a fundamental understanding of precipitation processes for optimal recovery of contaminant elements (for a novel zinc process case study), considering the quantitative relationship between all major physico-chemical and engineering features. This will lead to enhanced process designs to meet techno-economic, environmental and operability objectivesRead moreRead less
