Overview

Biography:

Dr Vaughan is Senior Lecturer in the University of Queensland School of Chemical Engineering, Director of the UQ RT Bauxite and Alumina Technology Centre and leader in the Hydrometallurgy Research Group. 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. Before joining UQ James gained valuable experience as a research engineer in industry, working for Placer Dome Mines and BHP Billiton.

Research:

The research focuses on the fundamental aspects of leaching; ion exchange, adsorption and precipitation reactions. The potential to apply nanofiltration technology for novel aqueous phase separations is also being studied. These projects are of interest to the base metals, precious metals and alumina refining industries.

Two new nickel processing technologies developed at the University of Queensland are being commercialized. The first is a method to separate nickel from cobalt and manganese contained in hydroxide intermediates by oxidative leaching. The second is a method of extracting nickel and cobalt from process streams using ion exchange resin and recovering the metal to the refinery by selective ammonia elution. A new process is also being developed for treating copper ores which takes advantage of the synergies between the hydro and pyrometallurgical routes.

Teaching and Learning:

  • Lecturer and coordinator of the course Aqueous Solution Processing & Electrometallurgy (MINE4204)
  • Lecturer in the course Reaction Engineering (CHEE3005)
  • Lecturer in the course Physical & Chemical Processing of Minerals (MINE2201)

Projects:

  1. A novel low-energy process route for primary copper production utilising synergistic hydro- and pyro-metallurgical processes
  2. Bayer process fundamentals
  3. Mercury in the Bayer process
  4. Selective acid leaching of nickel from mixed nickel-cobalt hydroxide precipitate
  5. Selective ammonia elution of nickel and cobalt from ion exchange resin

Research Interests

Research Impacts

My research in hydrometallurgy is used for process development and improvement which has an impact in the base metals, precious metals and alumina industries. Examples of contributions are as follows:

  • Selective acid leach process for refining mixed Ni-Co hydroxide precipitate
  • Synergistic hydro/pyro metallurgical process for low energy copper production
  • Chloride brine process for recovering Pt/Pd from used automobile catalysts
  • Selective ammoniacal elution of Ni and Co from ion exchange resin
