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.

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. 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
Nano-scale modification of gold surfaces for sensing mercury from gaseous effluents of alumina refineries. The Australian alumina industry contributes more than $5.4 billion export income annually. It is also a major driver of the rural economy with all but one of Australia's seven alumina refineries located in rural areas. In response to the industry's attempts to reduce the environmental impact of its processes, this project will conduct basic strategic research into the interaction between m ....Nano-scale modification of gold surfaces for sensing mercury from gaseous effluents of alumina refineries. The Australian alumina industry contributes more than $5.4 billion export income annually. It is also a major driver of the rural economy with all but one of Australia's seven alumina refineries located in rural areas. In response to the industry's attempts to reduce the environmental impact of its processes, this project will conduct basic strategic research into the interaction between mercury vapour and gold surfaces at the nano-level. Our principal aim is to develop mercury sensor technology suited to alumina refineries. This innovative technology will be a significant breakthrough in the control of mercury emissions and have many other applications.

Heat capacities of Bayer liquors to 300C. Alumina refining is one of Australia's most important industries, earning ~$6 billion per year export income. However, major productivity gains are required for Australian producers to remain globally competitive. More accurate thermodynamic calculations, covering the full plant operating range, are seen by the industry as an important way to increase productivity, minimise energy consumption and cut greenhouse emissions. To achieve these aims, we must e ....Heat capacities of Bayer liquors to 300C. Alumina refining is one of Australia's most important industries, earning ~$6 billion per year export income. However, major productivity gains are required for Australian producers to remain globally competitive. More accurate thermodynamic calculations, covering the full plant operating range, are seen by the industry as an important way to increase productivity, minimise energy consumption and cut greenhouse emissions. To achieve these aims, we must extend current theoretical understanding and establish an experimental capability, hitherto unavailable in Australia, for measuring heat capacities and densities of solutions to temperatures as high as 300 C.Read moreRead less
Modelling Bayer Plant Liquors for Industrial Process Simulations. Alumina refining is one of Australia's most important industries but it exists within an increasingly competitive global market. More meaningful computer simulations of the Bayer process, covering conditions far beyond current plant operating ranges, are seen by Australian producers as an important way to increase future productivity, minimise energy consumption and cut greenhouse emissions. To achieve these aims, we must develop ....Modelling Bayer Plant Liquors for Industrial Process Simulations. Alumina refining is one of Australia's most important industries but it exists within an increasingly competitive global market. More meaningful computer simulations of the Bayer process, covering conditions far beyond current plant operating ranges, are seen by Australian producers as an important way to increase future productivity, minimise energy consumption and cut greenhouse emissions. To achieve these aims, we must develop hitherto unavailable modelling capabilities for predicting the behaviour of Bayer plant liquors. The more robust thermodynamic models developed in this project will enable more realistic simulations, which are a prerequisite for innovative process design and optimisation.Read moreRead less
