Research Topic:
|
Mathematical analysis of a novel method of mineral fractionation
|
Brief Outline:
|
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.
|
Detailed Description:
|
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.
