PhD Scholarship

Supervisor: Dr Roberto Moreno-Atanasio and Laureate Professor Kevin Galvin - The ARC Centre of Excellence for Enabling Eco-Efficient Beneficiation of Minerals is seeking creative and innovative PhD applicants to join our national collaborative Centre, to develop transformational technologies to reduce energy and water consumption and increase metals recovery. This project will develop a computer model to describe a novel method for dry separation of minerals.

There are major advantages in mineral processing if we can achieve separations through waterless processing, with significant savings in water consumption, elimination of tailings dams, and reduction in energy consumption. This project aims to develop a Discrete Element Model (DEM) to describe the essential granular physics of a novel dry separation mechanism, the Sink-Hole fluidiser, to achieve early gangue rejection of particles larger than 2 mm.

The project, which is based as the University of Newcastle, is supervised by Dr Moreno-Atanasio and Laureate Professor Kevin Galvin, and involves researchers from Melbourne University and Curtin University, with direct connections to the minerals industry. The Sink-Hole Fluidiser system consists of a dry fluidised bed subjected to vibration. The physical arrangement includes an upper screen that contains a relatively large hole, creating a sink-hole condition for sorting particles according to density. Particles of a high density fall through, while lower density particles pass across the hole.

Discrete Element Model (DEM) is the most common technique used in Chemical Engineering to investigate the behaviour of particulate solids in the presence and absence of fluid. DEM will be used to understand the principles of the sink-hole approach and to improve its performance.

This project helps to address Thematic Objective 1, using dry processing of coarse particles to help achieve massive reductions in energy and water consumption in minerals processing, and a reduction in the volume of tailings to be managed. The project will also help establish new insights into a novel separation mechanism that underpins what could become a major new technology for the industry.
