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.

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

This project aims to determine how non-conventional lithium and silicon isotopes can be used to understand groundwater processes using an innovative source-to-target approach. The project aims to apply these isotope tracers to trace the water cycle within a well constrained system: an island aquifer with a dense borefield which has been analysed using traditional isotopic techniques. Supporting hydrochemical data will be used to determine the relationship of the isotopes with environmental processes. The project impact will be the development of new methods to help understand our groundwater resource. The improved process understanding will be translated to groundwater management in general. The projects' focus on carbonate aquifer systems typical of coastal regions of southern, eastern and western Australia will have relevance to groundwater management in urban areas such as Perth and in rural areas for tourism and viticulture, and for management of natural resources in National Parks.Read moreRead less
Resilience of lake ecosystems to water-level manipulation. Which lakes recover from fluctuations in water level and which do not? Manipulations of water levels in lakes will need to intensify as droughts become more frequent. This project will develop robust ways of forecasting how lakes will respond to changes in manipulations of water levels, to minimise extinctions and maintain aesthetics and water quality.
