Overview

Biography:

Associate Professor James Vaughan is the Metallurgy Major Lead (https://my.uq.edu.au/programs-courses/requirements/plan/METAEC2455/2021) and head of the Hydrometallurgy Research Group within the School of Chemical Engineering. He obtained a Bachelor’s degree in Metallurgical Engineering at McGill University followed by Master of Applied Science and PhD degrees in Materials Engineering at The University of British Columbia in Canada. Before joining UQ, James gained experience as a research engineer with Placer Dome in gold and BHP in nickel. While at UQ James served as Director of the University of Queensland Rio Tinto Bauxite & Alumina Technology Centre and was Chief Investigator for the ARC Research Hub for Australian Copper-Uranium. He is currently a member of the TMS, CIM and AusIMM professional societies.

Research:

James' research focuses on the fundamental aspects of leaching, ion exchange and precipitation reactions as well as membrane separations. These projects are of interest to the base metals, precious metals and alumina refining industries as well as in the fabrication of value added materials such as lithium ion battery cathode precursors and zeolites.

Current Projects:

  1. Value-added cobalt refining technologies powering advanced batteries
  2. Extracting Queensland's rare earth elements sustainably
  3. New approach for producing zeolites from clay or mine tailings
  4. Inorganic membrane percrystallisation in hydrometallurgy
  5. Separating radionuclides from ore, concentrate or tailings

Teaching and Learning:

  • Course coordinator and lecturer in Hydrometallurgy and Electrometallurgy (MINE 4204)
  • Course coordinator and lecturer in Metal Production and Recycling (MINE 2201)

Research Interests

  • Hydrometallurgy
    leaching, precipitation, crystallisation, ion exchange, membranes, electrowinning

Research Impacts

My research in hydrometallurgy is used for process development and improvements. Examples of contributions are as follows:

  • Selective acid leach process for refining mixed Ni-Co hydroxide precipitate licensed to Pure Battery Technologies
  • Low cost zeolite production technology licensed to Zeotech
  • New approaches for bauxite impurity management in the production of alumina
  • A hydrometallurgical route for recovering Ni and K from agromined bio-ore
  • The synergistic copper process
