Overview

Biography:

Associate Professor James Vaughan is head of the Hydrometallurgy Research Group at the University of Queensland 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. Before joining UQ James gained experience as a research engineer in industry working for Placer Dome and BHP. While at UQ James has served as Director of the University of Queensland Rio Tinto Bauxite & Alumina Technology Centre and is currently Academic Director of Safety for the School and Technical Advisor for Pure Battery Technologies.

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.

Projects:

  1. The sandy desilication product process for high silica bauxite
  2. The synergistic hydro-pyro copper process
  3. Low intensity options for separating radionuclides from copper concentrate
  4. The selective leaching process for refining mixed nickel-cobalt hydroxide
  5. Inorganic membrane percrystallisation in hydrometallurgy

Teaching and Learning:

  • Course coordinator and lecturer in Aqueous Solution Processing & Electrometallurgy (MINE4204)
  • Lecturer in Engineering Investigation & Statistical Analysis (CHEE2010)
  • Previously lecturer in Reaction Engineering (CHEE3005)
  • Previously lecturer in Physical & Chemical Processing of Minerals (MINE2201)

Research Interests

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

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
  • A hydrometallurgical route for recovering Ni and K from agromined bio-ore

Qualifications

  • Doctor of Philosophy, The University of British Columbia
