Drag Force on Bubbles and Particles in Turbulent Flows. Australian exports are dominated by the minerals, metallurgical and chemicals industries, with minerals exports worth at least $40 billion annually. Many of the production processes are underpinned by the complex interaction between particles, bubbles and liquids. It is important that we understand the complex interactions taking place.

Australian exports are dominated by the minerals, metallurgical and chemicals industries, with minerals exports worth at least $40 billion annually. Many of the production processes are underpinned by the complex interaction between particles, bubbles and liquids. It is important that we understand the complex interactions taking place. This will enable us to improve existing operations and also to design completely new technologies, especially in the emerging fields of nano and biotechnology. This project is important because it adds to our knowledge in the national priority area of Transforming Australian Industries, and its success will ensure that our industries remain at the forefront of innovation and are globally competitive.

Depressing pyrite in selective flotation of complex polymetallic ores . This project aims to understand the reactions taking place on the major gangue (waste) mineral during the recovery of base-metal and precious minerals. The mining industry is processing low grade complex ores and experiencing difficulties in rejecting gangue minerals in mineral separation and metal extraction plants. The project will develop new technologies that manipulate these reactions to achieve mineral separation and ....Depressing pyrite in selective flotation of complex polymetallic ores . This project aims to understand the reactions taking place on the major gangue (waste) mineral during the recovery of base-metal and precious minerals. The mining industry is processing low grade complex ores and experiencing difficulties in rejecting gangue minerals in mineral separation and metal extraction plants. The project will develop new technologies that manipulate these reactions to achieve mineral separation and metal extraction efficiently and economically. These technologies may provide value in processing low quality complex polymetallic resources using low quality water, whilst halving the operating costs of mineral concentrators and providing corresponding reductions in harmful emissions.Read moreRead less
Depressing pyrrhotite in copper and gold flotation. The mining industry is processing low-grade ores associated with high amounts of waste minerals. Extracting metals from low-grade ores is very difficult with technical challenges in rejecting waste minerals. This project aims to understand the surface properties and the behaviour of a major waste mineral which is becoming increasingly problematic during the processing of copper and gold ores. New chemistry and chemical reagents will be develope ....Depressing pyrrhotite in copper and gold flotation. The mining industry is processing low-grade ores associated with high amounts of waste minerals. Extracting metals from low-grade ores is very difficult with technical challenges in rejecting waste minerals. This project aims to understand the surface properties and the behaviour of a major waste mineral which is becoming increasingly problematic during the processing of copper and gold ores. New chemistry and chemical reagents will be developed to efficiently and economically reject the waste mineral by manipulating the reactions that take place on its surface. This project expects to have immediate economic and environmental impacts through increasing metal production, cutting greenhouse gas emissions and applying new green reagents.Read moreRead less
