Three-dimensional flotation of fine particles. Three-dimensional flotation of fine particles. This project aims to research three-dimensional flotation of fine particles under both batch and continuous steady state conditions. In flotation, fine hydrophobic particles adhere to the two-dimensional surface of rising air bubbles, forming concentrate. In three-dimensional flotation, however, the particles adhere to and become embedded in a novel binder, forming a highly buoyant product.

This project aims to research three-dimensional flotation of fine particles under both batch and continuous steady state conditions. In flotation, fine hydrophobic particles adhere to the two-dimensional surface of rising air bubbles, forming concentrate. In three-dimensional flotation, however, the particles adhere to and become embedded in a novel binder, forming a highly buoyant product. The process is very selective and arguably 1000 times faster than conventional flotation. The project is expected to provide the knowledge required to achieve scale-up, so the technology can be used to recover high value product from tailings waste, eliminating the capital impediment and possibly transforming the entire mining industry.Read moreRead less

The project will provide new way of modelling the behaviour of individual flotation cells, and banks of cells in series. The project will provide benefits to existing operations such as the minerals and coal industries, which are heavy users of flotation technology. New insights into the behaviour of composite particles will lead to more efficient operations and a new way of scale-up in the design of full-scale plant, which will permit designers to optimise circuits and minimise capital and operating costs.Read moreRead less

Summary
A study of the bulk and surface responses of ores to high voltage pulses applied using a selFrag Lab. Minerals account for 40% of Australia's exports and mining is a major Australian employer. The health of the industry is integral to Australia's prosperity. Recent events have shown that mining cannot rely on high commodity prices but must continually seek efficiency improvements. This will be even more critical as production depends increasingly on low-grade ore deposits.

Minerals account for 40% of Australia's exports and mining is a major Australian employer. The health of the industry is integral to Australia's prosperity. Recent events have shown that mining cannot rely on high commodity prices but must continually seek efficiency improvements. This will be even more critical as production depends increasingly on low-grade ore deposits. Using selFrag Lab, the response of different ores to high voltage pulses will be studied to identify processes that liberate a greater percentage of valuable minerals while using less energy and less water and keeping toxic elements bound in larger waste particles. SelFrag-based research will therefore deliver major economic and environmental benefits to Australia.Read moreRead less

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

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.
