Particle scale modelling of dense medium cyclones in coal preparation. Australia is the world's biggest coal exporter, and black coal is Australia's largest export, worth around $A13.5 billion annually. Dense medium cyclones process the vast majority of tonnes fed to Australian coal preparation plants, and hence play a critical economic role in coal production.

Australia is the world's biggest coal exporter, and black coal is Australia's largest export, worth around $A13.5 billion annually. Dense medium cyclones process the vast majority of tonnes fed to Australian coal preparation plants, and hence play a critical economic role in coal production. This project aims at providing substantial design and operational improvements through the application of a novel combined continuum and discrete modelling method. Specifically, the improvements targeted relate to better process and product control, a decrease in unit energy consumption and improvements in productivity, which, together with the research training offered, will further enhance Australia's leading position in global coal industry.Read moreRead less
Optimisation of Coal Flotation Performance. The aim of this project is to improve the cleaning of coal by flotation across the whole particle size range with maximum rejection of mineral matter and decreased reagent consumption. The factors that influence coal flotation will be identified and used to predict coal flotation performance. In particular the ultimate separability of coal will be addressed through a unique combination of in- and ex- situ pulp chemical and physical measurements, embedd ....Optimisation of Coal Flotation Performance.

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
