Overview

My research focuses on mineral processing technologies, namely, grinding and flotation processes, with especial interest in understanding the complex interplay between ore mineralogy, mineral surface properties and process behaviour. I specialise in the application of advanced mineral surface characterisation techniques such as Time-of-Flight Secondary Ion Mass Spectrometry (ToF-SIMS) in mineral processing studies (e.g., grinding, flotation) to identify the key chemistry drivers of process behaviour. This knowledge is vital to understand the underlying mechanisms and devise solutions to improve process efficiency. I look to further develop advanced tools by integrating critical techniques such as ToF-SIMS, X-ray Photoelectron Spectroscopy, X-ray Tomography, Mineral Liberation Analysis and X-ray Fluorescence towards more comprehensive and faster mineral characterisation.

I am also interested in developing novel, highly selective reagents for mineral flotation to enable the processing of ores more efficiently, safely and environmentally friendly compared to the traditional reagents. Of particular interest is the use of biochemistries to develop more sustainable reagent technologies.

My research covers both the fundamental aspects underlying mineral processes (e.g., particle-bubble interactions) as well as applications in the minerals industry through close collaborations with the industry. I am Chief Investigator in the ARC Centre of Excellence for Enabling Eco-Efficient Beneficiation of Minerals (https://coeminerals.org.au/) aiming to achieve a step-change in mineral processing by increasing energy and water efficiency and reducing metal loss during processing. I am also part of the research team of the newly formed Collaborative in Coarse Particle Processing Research, a consortium of 9 industry partners, investigating the implementation of coarse particle technology in the industry.

Research Impacts

The mining industry is one of the cornerstones of the Australian economy. The metals demand will continue to grow into the future as the world transitions to renewable energy. Our research aims to advance our understanding of the fundamental aspects underpinning mineral processing and develop innovative technologies that allow the processing of minerals more efficiently, safely and with lower environmental impact. Working closely with the mining industry to address today’s challenges is a critical component of our research to ensure that the solutions we develop can be translated into industrial practice.
