Closing Date: 31 December 2022Apply Now

PhD Scholarship

Supervisor: Associate Professor Elham Doroodchi - 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 study uses new hydrodynamic techniques to quantify bubble-particle interaction in a turbulent environment, with the aim of determining how and why coarse particle detachment from bubble-multiparticle aggregates may occur in a flotation process.

The Centre’s inclusive and equitable culture is supported by specific equity and diversity initiatives, which will support all members to achieve their career goals.

The focus of this project is on development of a detachment model for coarse particles of different degrees of liberation in a turbulent environment.

In froth floatation process, the detachment is a key limiting factor for recovery of coarse particles. The detachment mechanisms are largely underpinned by a combination of forces acting on the particle. Some of these forces are unsteady due to the motion of particles on the bubble surface. An unsteady force analysis is therefore fundamental in understanding how the motion of particles on the bubble surface contribute to any detachment event. In this project, advanced and innovative experimental and theoretical approaches will be used to understand the detachment mechanism as a function of turbulent flow characteristics.

The outcome of this project will benefit minerals industry by providing the fundamental knowledge required for development of advanced separators for coarse particle beneficiation. This work will involve some travel to Queensland to work with Associate professor Kym Runge.
