PhD scholarship in minerals flotation  [May 24, 2022]

Location: ARC Centre of Excellence for Enabling Eco-Efficient Beneficiation of Minerals, University of Queensland, Australia

The ARC Centre of Excellence for Enabling Eco-Efficient Beneficiation of Minerals is the change agent committed to making minerals greener. To achieve this, the Centre is seeking creative and innovative PhD candidates to join our national collaborative Centre to develop new pathways to reduce energy and water consumption and increase metals recovery in the sector. The inclusive and equitable culture at our centre is supported by specific equity and diversity initiatives, which will support all members of the Centre to achieve their career goals.

We are seeking a full-time, highly motivated PhD candidate to perform high-quality research in the field of minerals flotation. The successful candidate will be working under the supervision of Prof Anh V. Nguyen at the School of Chemical Engineering. The candidate will join a multidisciplinary team in partnership with industry partners. This scholarship is funded by the ARC Centre of Excellence for Enabling Eco-Efficient Beneficiation of Minerals.

This project aims to fundamentally quantify the combined role of the frothers and hydrophobic particles in controlling froth drainage and coarsening by using state-of-the-art techniques such as sum-frequency generation spectroscopy, thin-film balance, and molecular dynamic simulation. The film drainage and rupture in the presence of coarse particles and frother molecules with different types and concentrations will be investigated and linked with the bubble coarsening in froth transient and equilibrium stability. Advanced knowledge obtained from this project will be used to optimize the frother type and dosage to promote the performance of coarse composite particle flotation.
