Closing Date: 31 January 2021Apply Now

PhD Scholarship

You will work as part of a team led by Associate Professor Jeff Hogan and Laureate Professor Kevin Galvin as part of the ARC 2020 Discovery Project “Enhanced fractionation of mineral particles according to density". This is cross-disciplinary research involving the application of advanced mathematical techniques to a problem in particle separations, relevant to the resources industry.

Mathematical formulas

In minerals processing, accurate resource assessment, plant design, and process assessment require knowledge of the mass distribution of the particles as a function of the particle density – the "washability data". The traditional sink-float method has traditionally been used to obtain the data, utilising a series of baths containing liquids of different densities. There are, however, significant health and environmental problems associated with the sink-float method, not least of which being that the heavy liquids used are toxic, environmentally hazardous, and costly. CI Galvin has developed new technologies for beneficiating particles in minerals processing, most notably the REFLUX™ Classifier used in gravity separation to separate particles according to their density using a water-based fractionation method. This project involves the development of an algorithm for the de-convolution of the fractionation data arising from the this new technology to produce accurate washability data at low cost and with dramatically reduced impact on human health and the environment.
