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
Engineering the sulphidising reactions for flotation of low quality ores. Engineering the sulphidising reactions for flotation of low quality ores. This project aims to engineer sulphidisation reactions to enhance the flotation of low quality ores for the minerals industry. Sulphidisation uses flotation to enrich base metal and precious minerals from low quality ores containing oxides and oxidised sulphides before expensive leaching or smelting. However, the current sulphidisation method is neit ....Engineering the sulphidising reactions for flotation of low quality ores. Engineering the sulphidising reactions for flotation of low quality ores. This project aims to engineer sulphidisation reactions to enhance the flotation of low quality ores for the minerals industry. Sulphidisation uses flotation to enrich base metal and precious minerals from low quality ores containing oxides and oxidised sulphides before expensive leaching or smelting. However, the current sulphidisation method is neither efficient nor widely used. This project will tailor sulphidisation reactions to generate desirable surface products that are not sensitive to flotation conditions. The intended outcome of this project is to provide a step change value in processing low quality resources while minimising the environmental effects of stockpiles.Read moreRead less
Regrinding chemistry and particle breakage mechanisms in increased surface hydrophobicity on fine and ultra-fine particles in mineral flotation. This project will study the effect of regrinding chemistry and particle breakage mechanisms on the redistribution of flotation collectors and the evolution of the metal oxidation species on mineral surfaces. New technologies will be developed to increase mineral surface hydrophobicity and therefore increase fine and ultra-fine particle flotation.
