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.

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
Improving the Continuous Copper Converting Process Using Ferrous Calcium Silicate Slags. Replacement of refractories due to slag attack is a major cost in the copper making process. Metallurgists need to find a better slag which retains the benefits of current slags but is less aggressive towards refractories. This project will assess the suitability of a newly proposed ferrous calcium silicate slag for continuous copper converting. The outcomes will be to: (1) provide fundamental knowledge of ....Improving the Continuous Copper Converting Process Using Ferrous Calcium Silicate Slags.

Metallurgists need to find a better slag which retains the benefits of current slags but is less aggressive towards refractories. This project will assess the suitability of a newly proposed ferrous calcium silicate slag for continuous copper converting. The outcomes will be to: (1) provide fundamental knowledge of the properties of the SiO2-CaO-FeO slag system, (2) provide data on the rate and mechanism of refractory attack by this slag and (3) enable the copper smelting industry to assess the potential of this slag to reduce operating costs.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

Modified activated carbons for recovery of gold from thiosulphate solutions. Thiosulphate is currently being considered by various international mining companies as an environmentally friendly alternative to cyanide for gold extraction. Although little is available in the open literature, most confidential research on recovery from thiosulphate leach slurries has focused on ion-exchange technology.

Thiosulphate is currently being considered by various international mining companies as an environmentally friendly alternative to cyanide for gold extraction. Although little is available in the open literature, most confidential research on recovery from thiosulphate leach slurries has focused on ion-exchange technology. Activated carbon as a more practical sorbent has been ignored completely owing to the general perception that it has a very low affinity for gold thiosulphate. On the basis of promising preliminary work, the aim of this project is to develop physically and chemically modified activated carbons with a high affinity for the sterically large gold thiosulphate complex. This project will aim to prove the hypothesis that the graphitic edges of an active carbon should be maximised and the organic active sites minimised for optimal adsorption.Read moreRead less
