Professor Anh Nguyen is the BMA (BHP Billiton Mitsubishi Alliance) Chair within the School of Chemical Engineering. He previously held academic positions at the University of Newcastle (Australia), the University of Utah (USA) and the Technical University of Kosice (Czechoslovakia). He was awarded an ARC (Australian Research Council) Queen Elizabeth II Fellowship and an Alexander von Humboldt Fellowship (Germany). His relevant publications include a research book on the colloidal science of flotation, 3 edited volumes, 16 book chapters (invited) and over 175 papers in refereed journals. He has editorial role on Advances in Colloid and Interface Science, and International Journal of Mineral Processing. He is an Elected Fellow of IChemE and AusIMM.


Professor Nguyen’s research interests embrace various aspects of colloid and interfacial science and engineering. The focus of his current research is on colloid and interface science of particles, bubbles and drops in surfactant solutions and saline water. The ultimate applications include coal and minerals processing, saline water usage and treatment, foliar fertilisers, smart self-cleaning materials, hydrophobic hydration and hydrates of natural gas, and particle separation. His research funding has come from industry partners (BMA, BHP Billiton, Xstrata, Rio Tinto, OneSteel, Agrichem) and agencies (ARC and ACARP). He is the Leader of the Mineral Processing and Interfacial Processes group.

Teaching and Learning: 

Professor Nguyen aims to encourage critical thinking, understanding and application of fundamental principles. The objective is to engage students by providing a stimulating learning process and environment at both undergraduate and postgraduate levels, relevant to the changing focus of national and global economic importance. He has taught a number of courses, including colloid and surface chemistry, particle processing and technology, unit operation, coal and mineral processing, flotation, computing and design laboratory, process modelling and simulation. He is currently an academic and international advisor for chemical and metallurgical engineering.

  1. Saline Water: molecular phenomena and engineering of saline water-air interfaces, water desalination, salt flotation, coal flotation in sea water and tailings processing. Foliar Fertilizers and Pesticides: self-assembly of colloids from evaporating droplets on leaf surfaces.
  2. Gas Hydrates: role of hydrophobic hydration and additives in gas hydrate formation for storage and transportation.
  3. Nanomaterials: surface self-assembly of surfactants and nanobubbles
  4. Hydrometallurgy: role of colloidal forces and surface chemistry in bacteria attachment in bioleaching, and leaching of minerals in brine solutions.
  5. Mineral Processing: role of microhydrodynamics and colloidal forces in bubble-particle collection in flotation, surface electrochemistry of sulfide flotation, flotation of ultrafine particles, flotation of coarse particles and composite particles.
  6. Foam and Froth: drainage and stability of thin films of saline water, role of particle shape and hydrophobicity in foam drainage and stability, foamed cements.
  7. Molecular (MC and MD) modeling and validation by VSFG spectroscopy of the partition of salt ions and surfactants at the interfaces of liquid films relevant to flotation, bubble columns and oil processing.
