Extraction of gold from thiosulfate leach liquors using selective magnetic ion exchange (MIEX) resins. Cyanide processes used for gold leaching can cause severe environmental problems. This proposal studies the use of thiosulfate as an alternative, concentrating on the design and synthesis of new functionalised magnetic ion-exchange resins, which will act as selective adsorbents for the gold thiosulfate complex and thereby facilitate the implementation of this efficient, low environmental impact ....Extraction of gold from thiosulfate leach liquors using selective magnetic ion exchange (MIEX) resins. Cyanide processes used for gold leaching can cause severe environmental problems. This proposal studies the use of thiosulfate as an alternative, concentrating on the design and synthesis of new functionalised magnetic ion-exchange resins, which will act as selective adsorbents for the gold thiosulfate complex and thereby facilitate the implementation of this efficient, low environmental impact process. Since the leaching is typically applied to ores rich in copper, resins for the recovery of copper will also be designed. Laboratory proving trials will be conducted and successful candidates will be considered for future commercialisation of a Resin-in-Pulp leaching and recovery process.Read moreRead less
Synthetic phenazines for enhanced biogas production from renewable and non-renewable resources. Methane (biogas) has a large role to play in meeting the energy needs of the human race globally whilst reducing greenhouse gas emissions. Microbial communities are responsible for biogas production from non-renewable (coal) and renewable (food waste) resources. This project seeks to: increase biogas yields by redirecting electron flow towards biogas producing microbes using electrochemically active p ....Synthetic phenazines for enhanced biogas production from renewable and non-renewable resources. Methane (biogas) has a large role to play in meeting the energy needs of the human race globally whilst reducing greenhouse gas emissions. Microbial communities are responsible for biogas production from non-renewable (coal) and renewable (food waste) resources. This project seeks to: increase biogas yields by redirecting electron flow towards biogas producing microbes using electrochemically active phenazines; understand the molecular mechanism by which phenazines increase biogas yields; and, assess the environmental consequence of phenazine application to coal seam gas production and anaerobic digestion of food waste. Phenazines are likely to emerge as a safe and cost-effective technology for improved biogas generation.Read moreRead less
Three-dimensional Bayesian Modelling of Geological and Geophysical data. The project aims to develop technologies enabling rapid informed decision-making related to the management of natural resources, including critical metals, copper and water. This new technology will support a greener future, securing our energy future, our access to clean water and reduce the mining footprint. Expected outcomes include an enhanced capability in interoperable, integrated three-dimensional geological and geop ....Three-dimensional Bayesian Modelling of Geological and Geophysical data. The project aims to develop technologies enabling rapid informed decision-making related to the management of natural resources, including critical metals, copper and water. This new technology will support a greener future, securing our energy future, our access to clean water and reduce the mining footprint. Expected outcomes include an enhanced capability in interoperable, integrated three-dimensional geological and geophysical modelling in order to predictively characterise sub-surface geology. The outcome will be an open-source forecasting dashboard enabling decision making while considering underlying risk related to resource extractions and management with significant benefits to the Australian society (lower emissions, clean water).Read moreRead less
