Advanced studies on the hydrometallurgy and electrochemistry of primary copper sulphide ores. The exploitation of low quality copper ores is hampered by our poor understanding of the fundamental chemistry involved. In this project, advanced techniques will be developed to understand the leaching of copper to a level of detail not obtained before. This will allow mining companies to extract copper with minimal environmental footprint.
Redox processes in Bayer liquors. Alumina, and the aluminium produced from it, are amongst Australia's most important mineral commodities, earning about $8 billion p.a. in exports. However, ongoing technological improvements are needed for Australian producers to remain globally competitive. This project addresses a key problem in alumina production - the behaviour of organic impurities - which will help to increase industrial productivity and reduce energy consumption.

However, ongoing technological improvements are needed for Australian producers to remain globally competitive. This project addresses a key problem in alumina production - the behaviour of organic impurities - which will help to increase industrial productivity and reduce energy consumption. Insights gained from this research will also minimize the environmental and occupational health impacts of various process emissions, making the industry more sustainable.Read moreRead less
Development of an efficient oxygen-thiosulfate process for the recovery of gold from ores. Gold is currently recovered from the ore by a cyanide leaching process. This high risk procedure is used because there is currently no safe alternative. The research we propose to undertake will investigate a novel thiosulfate-oxygen process to dissolve gold. Successful completion of the project will identify the mechanism of the process and could lead to the replacement of the highly toxic cyanide with th ....Development of an efficient oxygen-thiosulfate process for the recovery of gold from ores. Gold is currently recovered from the ore by a cyanide leaching process. This high risk procedure is used because there is currently no safe alternative. The research we propose to undertake will investigate a novel thiosulfate-oxygen process to dissolve gold. Successful completion of the project will identify the mechanism of the process and could lead to the replacement of the highly toxic cyanide with the non toxic thiosulfate. Thus the proposed project has the potential to substantially alter the gold recovery process, particularly in an era where environmental and public concerns exist over the use of cyanide.Read moreRead less

Polyoxometalate Clusters: Catalytic Chemistry in Solution and Condensed States. Polyoxometalate cluster anions are soluble metal-oxygen clusters that are cheap, robust and non-toxic.
Conditions for systematic tuning of redox potentials over the range +2 to -3 V have become accessible via certain photo-active polyoxometalates. The same system can provide powerful oxidants (that rival chlorine) and powerful reductants (that rival potassium).
