MINJAR GOLD - INVESTIGATION OF THE INFLUENCE OF CLAY ON GOLD EXTRACTION (Old ID 27376)
Role
Principal Investigator
Description
The main objective of this thesis is to explore possible ways of mitigating issues associated with the presence of clay in a Carbon in Pulp (CIP) plant. It is hypothesized that heat treatment is an effective way of eliminating these issues as well as providing several subsequent benefits such as improvements to grinding and recovery. Yet, the efficacy of heat treatment is largely determined by the characteristics unique to each clay species. Thus, preliminary testing using equipment in the James Cook University Analytical Centre such as the Scanning Electron Microscope (SEM), X-ray Diffraction (XRD) and Thermogravimetric Analysis (TGA) is necessary. This will provide the optimal heat treatment temperature, where the impacts of the heat treatment on viscosity in these conditions can be determined. Furthermore, secondary benefits such as improvements to recovery and grinding will also be quantified. This method allows for a thorough understanding of the impacts of heat treatment and will determine whether it is an effective approach to mitigating issues associated with the presence of clay.
