Innovative thermodynamic process control - the key to sustainable metal use. Large amounts of electronic goods such as computers and mobile phones are discarded each year in Australia. They contain both valuable and toxic metals so dumping them as landfill is unacceptable. Australia has a smelting method which could be adapted to reprocess this waste to recover the valuable metals, returning them for reuse. It would also safely handle the toxics. This project will determine the appropriate s ....Innovative thermodynamic process control - the key to sustainable metal use. Large amounts of electronic goods such as computers and mobile phones are discarded each year in Australia. They contain both valuable and toxic metals so dumping them as landfill is unacceptable. Australia has a smelting method which could be adapted to reprocess this waste to recover the valuable metals, returning them for reuse. It would also safely handle the toxics. This project will determine the appropriate smelting strategies and control methods. As a result, transportation of toxic materials overseas will be eliminated, environmental hazards will be reduced and our sustainable use of metals will be increased.Read moreRead less
The effect of contaminant carbon films on the leaching of gold. A major problem in cyanidation is preg-robbing, which results in severe gold losses to tailings. Too much emphasis has been placed on the blinding and characterisation of free carbon or graphite particles, instead of considering carbon or graphite as a layer on top of other ore particles. It is the aim of this project to investigate the effect of contaminant carbon layers on the leaching of gold from sulphide ores. The understanding ....The effect of contaminant carbon films on the leaching of gold. A major problem in cyanidation is preg-robbing, which results in severe gold losses to tailings. Too much emphasis has been placed on the blinding and characterisation of free carbon or graphite particles, instead of considering carbon or graphite as a layer on top of other ore particles. It is the aim of this project to investigate the effect of contaminant carbon layers on the leaching of gold from sulphide ores. The understanding of the exact role of carbon layers on mineral surfaces in both preg-robbing and leaching is essential to devise process strategies that could lead to improved extraction.Read moreRead less

The development of resin and polymer based technologies for the recovery of copper and cyanide from gold processing tailings streams. This is a fundamental study on the use of resin and polymer-based ligands to recover copper and cyanide from gold cyanidation tailings. This process is environmentally more acceptable than other recovery methods, as it does not involve the use or generation of harmful species, such as HCN. It also has the advantage that copper metal and cyanide are recovered as pr ....The development of resin and polymer based technologies for the recovery of copper and cyanide from gold processing tailings streams. This is a fundamental study on the use of resin and polymer-based ligands to recover copper and cyanide from gold cyanidation tailings. This process is environmentally more acceptable than other recovery methods, as it does not involve the use or generation of harmful species, such as HCN. It also has the advantage that copper metal and cyanide are recovered as products from the copper cyanide containing streams. Thus the proposed project has the potential to substantially alter the gold recovery process, particularly in an era where environmental and public concerns exist over the discharge of cyanide species into tailings dams.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
