Iron - a solution for uranium resource recovery and pollution response. This project aims to determine key processes controlling uranium transport and fate in natural and engineered environments. This will result in improved efficiency in extracting uranium from tailings and subsurface deposits, reduced risk of contamination of water supplies, and improved management of radioactive waste repositories.
Advanced Nanocomposites for Enhanced Containment of Hyper-Saline Leachate. This research project seeks to apply nanotechnology approaches to develop tailored materials that are green and cost-effective, which minimise groundwater contamination by hyper-saline industrial leachates and process waters. Australian industries will benefit from lower costs associated with storage, processing and reclamation of process waters, as well as from reduced environmental fines levied by the Environmental Prot ....Advanced Nanocomposites for Enhanced Containment of Hyper-Saline Leachate. This research project seeks to apply nanotechnology approaches to develop tailored materials that are green and cost-effective, which minimise groundwater contamination by hyper-saline industrial leachates and process waters. Australian industries will benefit from lower costs associated with storage, processing and reclamation of process waters, as well as from reduced environmental fines levied by the Environmental Protection Agency due to significantly reduced barrier failure and groundwater contaminations. Australian businesses involved in manufacture, design and construction of environmental barrier systems will have access to new materials and improved technology.Read moreRead less
Development and modelling of dust suppression technology. Over 50 per cent of Australia's export income is derived from industries that rely on bulk materials handling and processing. With greater throughputs and increasing integration of transport routes, ports and residential communities, more pressure is being placed on industry to control its dust emissions. There is an urgent need for Australia to invest in a more unified and scientific approach to develop and optimise dust suppression tech ....Development and modelling of dust suppression technology. Over 50 per cent of Australia's export income is derived from industries that rely on bulk materials handling and processing. With greater throughputs and increasing integration of transport routes, ports and residential communities, more pressure is being placed on industry to control its dust emissions. There is an urgent need for Australia to invest in a more unified and scientific approach to develop and optimise dust suppression technology for mining and export infrastructure. This project will help secure the sustainability of Australia's bulk exports by ensuring that products can be handled, conveyed and loaded safely and reliably. It will also reduce the risk of exposing workers and the community to unsafe concentrations of airborne dust.Read moreRead less
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

Summary
Particulate Science and Technology Network. Particulate Science and Technology (PST) is a rapidly developing interdisciplinary research field concerned with particle-related phenomena at different time and length scales and represents a very significant research and development effort in Australia for many years. This network is formed by linking the world-recognized research centres/groups with different expertise. Its aim is to provide greater collaboration among the Australian and overseas re ....Particulate Science and Technology Network. Particulate Science and Technology (PST) is a rapidly developing interdisciplinary research field concerned with particle-related phenomena at different time and length scales and represents a very significant research and development effort in Australia for many years. This network is formed by linking the world-recognized research centres/groups with different expertise. Its aim is to provide greater collaboration among the Australian and overseas researchers and enhance the scale and focus of particulate research. It will help develop and maintain Australia's leading position in PST, generating massive research outcomes and training that can lead to improvement in resource, energy, process and allied industries.Read moreRead less
Bio-electrochemical sulfate reduction and sulfur recovery without external carbon source. Highly acidic waterways and mining wastewaters create major environmental challenges in inland Australia. This project will use novel, solar driven biological processes to remove the acid and metals from these streams and enable beneficial reuse of the water and other resources recovered in the process.
BauxsolTM based grouts and shotcretes for the control of acid rock drainage. Acid rock drainage (ARD) occurs where sulphides (mostly pyrite, but also sulphides of other metals) are exposed to oxygen and water; the estimated global liability from ARD is over US$300 billion. There is currently no cost-effective way to prevent the release of acid and heavy metals from exposed sulphide minerals especially at abandoned mine sites. This study investigates the use of BASECONTM transformed bauxite refin ....BauxsolTM based grouts and shotcretes for the control of acid rock drainage.

There is currently no cost-effective way to prevent the release of acid and heavy metals from exposed sulphide minerals especially at abandoned mine sites. This study investigates the use of BASECONTM transformed bauxite refinery residues (BauxsolTM) to grout waste rock dumps and tailings dams and to develop concretes that can be sprayed on open cut walls and floor to prevent and treat the ARD as it is formed.Read moreRead less

There is currently no cost-effective way to prevent the release of acid and heavy metals from exposed sulphide minerals especially at abandoned mine sites. This study investigates the pelletisation and use of neutralised bauxite refinery residues (Bauxsol?) to treat flowing metal-rich acid mine drainage waters using reactive-barriers that will neutralise acid and remove heavy metals without impeding flow.Read moreRead less

This project aims to develop an innovative assessment of dioxin formation through analysis and speciation of its precursors (Cl and Cu). Iron ore sintering is the industrial process with the highest emissions of dioxins and furans to the environment in Australia, which are amongst the most toxic substances produced by man. The aim of this project is to conduct critical investigations required for control of dioxin emissions during iron ore sintering. The expected outcome of this project is the development of control mechanisms for the process conditions responsible for dioxin formation. This should provide significant benefits, such as assisting the Australian iron ore industry to address the environmental requirements of their international trade partners and sustain their iron ore exports.Read moreRead less
