Froth flotation is the most widely applied technique for the selective separation of valuable mineral from gangue mineral particles. This project aims to optimize the selective separation of valuable minerals from gangue minerals within the froth zone of flotation. This project has very high national significance as deficiencies in the froth zone performance of industrial flotation plants, leads to a significant loss of valuable mineral from mineral concentrates, as well as a reduction in concentrate grade and quality. An expected outcome of this project will be a series of new tools and methodologies to optimize froth zone performance, which will have industry wide application.Read moreRead less
Optimizing tailings dewatering through interfacial chemistry and particle interactions. This project aims to improve the dewatering behaviour of waste tailings from mineral processing activites. Dewatering and disposal of tailings containing fine particles are serious issues which confront the mineral industry. Effective dewatering of tailings is determined by particle-solution interfacial chemistry and particle interactions. These properties will be manipulated by matching the molecular arch ....Optimizing tailings dewatering through interfacial chemistry and particle interactions. This project aims to improve the dewatering behaviour of waste tailings from mineral processing activites. Dewatering and disposal of tailings containing fine particles are serious issues which confront the mineral industry. Effective dewatering of tailings is determined by particle-solution interfacial chemistry and particle interactions. These properties will be manipulated by matching the molecular architecture and functionality of flocculants to mineral particle surface chemistry. Optimization of tails interfacial chemistry and particle interactions through conventional and non-conventional flocculants will be investigated and electoosmosis will be applied to achieve maximum dewatering behaviour.The scientific and environmental outcomes will be beneficial to all stakeholders.Read moreRead less
The flotation of oxide minerals using hydroxamate collectors. Australian and world mineral resources are declining in quality as we exploit the richest sulfidic ore deposits. This is increasing our reliance on concentration and beneficiation processes to improve the economics of the selective recovery of minerals from lower grade and, increasingly, oxide or lateritic ore bodies. In addition, greater emphasis is being placed on our environmental stewardship and the need to remove hazardous mater ....The flotation of oxide minerals using hydroxamate collectors. Australian and world mineral resources are declining in quality as we exploit the richest sulfidic ore deposits. This is increasing our reliance on concentration and beneficiation processes to improve the economics of the selective recovery of minerals from lower grade and, increasingly, oxide or lateritic ore bodies. In addition, greater emphasis is being placed on our environmental stewardship and the need to remove hazardous material from the concentrate streams. This proposal will develop improved methods and techniques that will facilitate better, cleaner separations and recovery of the valuable oxide mineral components using Australian-developed flotation reagents.Read moreRead less
Chemistry of uranium extraction - studies on the dissolution of uranium ores in a complex solution matrix. Olympic Dam is the world's largest uranium deposit. With a planned massive expansion of the mine's operations, it could generate more than $10b per year. The mineral ores found there, however, are highly complex and poorly understood.
