Qualifications
BAppSci U.S.M'sia, PhD Melb., FIEAust., Sr MAIChE, MAusIMM
Key research
Surface Chemistry, Microstructure and Rheology of suspensions of clay, ceramic oxides such as zirconia, alumina, silica and titania;
Inverse problems in rheometry, chemical kinetics and population balances in flocculation;
Publications
Professor Leong has published over 130 journal papers and 60 conference papers. His publications have received more than 2500 citations and He has a h-index of 28 (see google scholar). His research results appeared in two important textbooks on rheology; a)The Structure and Rheology of Complex Fluids and b) Colloidal suspension rheology. Professor Leong has a rheological ageing model named after him.
Roles, responsibilities and expertise
I control the suspension rheology by employing surface chemistry tools to regulate the surface or interparticle forces in slurry processing.

Problems encountered and solved:
I) ability to solve gelation problem in the production of ammonium phosphate slurries
ii) ability to reduce the pumping cost of mineral/tailings slurries with low cost composite additives
iii) ability to enhance the performance clay/mineral separation in iron ore slurries.
Future research
I) Clay gel, surface chemistry, microstructure and ageing rheological behaviour
ii) Hydrometallurgical methods of enhancing rare Earth Metal extraction.
iii) Sequential layering of polyelectrolytes on ceramic oxide particles in suspension and its rheological behaviour.
iv) Iron oxide separation methods and purity
Funding received
I) MRIWA Scholarship and Top-up 2016-2019
Industrial relevance
Low cost composite additives developed can be used to reduce the pumping cost of mineral/tailing slurries, improve the effectiveness of the separation processes, reduce process water requirement and enhance mineral solids throughput.
