Such systems are of interest to the industry partner as they represent the expected characteristics of ....Iron and Silica Co-precipitation from Industrial Zinc solutions. The aim of this research project is to gain a molecular level understanding of the physical processes that occur during the co-precipitation of iron and silica from electrolytic zinc liquors. The research program will be specifically focussed on systems in which similar concentrations of iron and silica are present in the liquor. Such systems are of interest to the industry partner as they represent the expected characteristics of future process requirements, but they are also of broader relevance to a range of mineral processing industries, as iron and silica occur as impurities in many mineral ores.Read moreRead less

The expected outcomes of the project are the preparation and development of sophisticated electrodes for solar cells, the main advantage of which resides in their designed chemical and morphological properties. The resulting electrodes have the potential to improve the efficiency of the solar cells over current industrially used materials. The products and mechanisms developed are envisaged to be amenable to large scale-up in industry. Hence, at a future date, there is the potential to fabricate the electrodes in Australia and then export the materials or technology internationally. This will benefit the Australian economy through employment of Australians and income generated through exports.Read moreRead less
Environmentally Benign Flotation Chemicals. The research described in this proposal and the anticipated outcomes are concerned with replacing toxic and environmentally hazardous chemicals used in the mineral processing industry with benign chemicals that are biodegradable and have low toxicity. Replacing these chemicals reduces the risk of workplace injuries and damage to the environment that could be caused by industrial accidents.
Matching flotation concentrate composition to downstream processing in copper production at the Olympic Dam operations of BHP Billiton. This research is important for the Australian and South Australian economies. There are both large capital and operating costs benefits if a successful and robust mineral separation can be achieved. Being able to separate different copper sulphide minerals in copper concentrates will have global significance.

Being able to separate different copper sulphide minerals in copper concentrates will have global significance. In the particular case of Olympic Dam mine, the impact of being able to separate the copper sulphide minerals at the mineral processing stage is a significant reduction in operating costs, which is a result of reduced ore handling, mining and smelting costs.Read moreRead less
Optimising the Recovery of Fine and Coarse Particles in Mineral Flotation. The collection of fine (<10 microns) and coarse (>100 microns) mineral particles by gas bubbles is the very heart of the selective froth flotation process. In the flotation of minerals, losses of fine and coarse value minerals equate to approximately $500M annually in Australia alone. The significance of flotation to the Australian economy may be judged from the fact that over $39b in commodity exports was derived from t ....Optimising the Recovery of Fine and Coarse Particles in Mineral Flotation. The collection of fine (<10 microns) and coarse (>100 microns) mineral particles by gas bubbles is the very heart of the selective froth flotation process. In the flotation of minerals, losses of fine and coarse value minerals equate to approximately $500M annually in Australia alone. The significance of flotation to the Australian economy may be judged from the fact that over $39b in commodity exports was derived from the minerals and energy industries in 2001, rising to well over $75b in 2005 (Australian Bureau of Statistics). These industries produce mineral concentrates of specific interest to our Industry Partner, such as copper, nickel, zinc and coal.Read moreRead less

The development of more efficient methods for the retrieval of the Cu is of considerable economic importance to Australian minerals processing companies. We aim to develop methodologies allowing the more efficient :
- separation of chalcopyrite and pyrite;
- leaching of Cu from ores and tailing in a heap leach environment and
- leaching of Cu in a concentrated chalcopyrite-pyrite reactor environment.
These aims will be achieved via an integrated surface-solution speciation approach allowing the manipulation of surface properties.
