Developing a Methodology for Characterising in-situ Viscosity Profiles in Tumbling Mills
(Supervisors: Dr I Govender, Dr AN Mainza, Prof J-P Franzidis)
The objective of this project is to characterize in-situ viscosity distributions in tumbling mills based on a combination of shear rate data from PEPT experiments, and rheological characterization data from rheometer experiments. Read more...

The influence of phyllosilicate mineralogy on the rheology of mineral slurries
(Supervisors: Assoc Prof DA Deglon, Dr M Becker, Prof J-P Franzidis)
In the past, the processing of phyllosilicate mineral bearing ores has been problematic with difficulties such as reduced flotation rates and complex tailings treatment arising. Read more...

PhD Project title

The development of a simplified system for measuring the passage of particles on and through moving screen surfaces using discrete element modelling (DEM) and positron emission particle tracking (PEPT)
(Duration: April 2013 to Dec 2015)
Currently, the design and scale-up of screens still relies on rules of thumb and empirical factor methods. To go beyond the current state-of-the-art in screen modelling requires a clear understanding of the particle motion along a dynamic (vibrating) inclined plane. Read more...

MSc Project title

Technical Feasibility of South Africa Coal Water Mixtures (CWMs)
(Duration: Jan 2014 to Dec 2015)
The flow properties of a coal slurry suspension are highly dependent on the properties of the coal, particles suspended within the fluid, volume concentration and addition of chemical additives. Rheological studies focus on measuring these fluid properties using rheometers. Read more...
