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. Tasmania has substantial critical metal resources (e.g., W, Co, Sn, Ni, Mg) with the potential to contribute significantly to growth in  critical metals inventory. Extraction of critical metals from ores and waste materials can be challenging and pose potential barriers to cost-effective recovery that need to be addressed. These include potential issues with crushing and grinding, separation of critical metals from gangue, and efficient energy use. These issues apply to extraction as by-products from operating metal mines and extraction from legacy waste materials.
This PhD project will optimise methods, and devise new workflows for critical metals processing
as by-products from one or more operating metal mines and/or from one or more legacy mine waste facilities. The focus will be on W, Co, Mg, Ni and/or Sn extraction, depending on the study site. The candidate will:

  • Characterise critical metal distribution through sampling, petrophysical and geochemical analyses
  • Determine critical metal deportment through detailed laboratory analyses (LA-ICP-MS, XRD, SWIR, SEM, etc.)
  • Evaluate and test the feasibility of critical metal extraction
  • Use these research findings to create novel characterisation and testing workflows for evaluating critical metal extraction 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.
