About the research project

Critical metals are vital, scarce resources required for modern technology, infrastructure and the transition to a renewable energy future. In order to address global supply issues, growth in critical metal resources and advances in their extraction technologies are required. One potential pathway to critical metals production involves recovery of critical metal resource streams from areas already impacted by mining, in particular through waste reprocessing from historical and legacy mine waste facilities. Economic recovery of critical metals from mine wastes has the potential to improve environmental sustainability through the responsible use of resources, enhance the value of mining operations and minimise environmental footprints, thereby significantly benefiting regional and rural communities and the environment whilst also growing critical metals inventory.

This PhD project will develop novel methods of characterising and processing critical metals from one or more historic or legacy mine waste facility in Western Tasmania. Primary focus will be on cobalt, ranked 6th on Geoscience Australia's (GA's) list of critical metals, with other critical metals to be considered if present in significant amounts. The candidate will:

  • Characterise critical metal distribution throughout one or more mine waste facilities through field sampling, geophysical and geochemical surveying and characterisation of waste materials (rocks, minerals, waters).
  • Determine critical metal deportment through detailed laboratory analyses (LA-ICP-MS, XRD, SWIR, SEM, etc.).
  • Evaluate the feasibility of critical metal extraction from mine wastes and optimal strategies for environmental management of reprocessed waste.
  • Use these research findings to create novel characterisation and deportment toolboxes and workflows for evaluating critical metal deportment in mine wastes and creating opportunities for critical metal production.

This project will be conducted as part of a new CODES critical metals research initiative. The candidate will work in a multidisciplinary research team and collaborate with a large industry sponsor group.
