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

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
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
In situ microbial conversion of coal to methane: Biotechnology development for clean use of Australian coal. We will develop a biotechnology that uses native microorganisms to accelerate the underground conversion of coal to methane. Approximately 90% of Australia’s coal resources cannot be accessed economically using traditional mining technologies. A technology that converts coal to methane could generate an energy supply worth an estimated $60 billion, foster the development of an energy indu ....In situ microbial conversion of coal to methane: Biotechnology development for clean use of Australian coal. We will develop a biotechnology that uses native microorganisms to accelerate the underground conversion of coal to methane. Approximately 90% of Australia’s coal resources cannot be accessed economically using traditional mining technologies. A technology that converts coal to methane could generate an energy supply worth an estimated $60 billion, foster the development of an energy industry now in its infancy, and generate numerous new employment opportunities. Environmentally, methane is a cleaner burning fuel than coal, uses much less water for processing and generates the same quantity of electricity with lower CO2 emissions. This project highlights the fact that Australia’s microbial diversity is a resource we cannot afford to ignore.Read moreRead less
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. 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 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
Mechanisms for Pyrite Oxidation Control in Acid Mine Drainage. The annual costs of acid rock drainage (ARD) management at operating sites in Australia are $120M p.a.; over 15 years, a total cost of $1.8 billion for the whole industry. There are limitations to the ability of existing systems to cope with high capacity ARD, to the long-term effectiveness of these systems and high potential costs/liability of remediation. The value of the project outcomes to industry and government will be in reduc ....Mechanisms for Pyrite Oxidation Control in Acid Mine Drainage. The annual costs of acid rock drainage (ARD) management at operating sites in Australia are $120M p.a.; over 15 years, a total cost of $1.8 billion for the whole industry. There are limitations to the ability of existing systems to cope with high capacity ARD, to the long-term effectiveness of these systems and high potential costs/liability of remediation. The value of the project outcomes to industry and government will be in reduction of ARD release, well-understood long-term outcomes, reduced cost of treatments and improved control. The scale of these savings is in the tens of $M p.a. but also in potential improvements in environment (acid and toxic metals in streams), health and social quality of life in mining areas and towns.Read moreRead less
