Accelerating Consolidation and Closure of Mine Tailings Storage Facilities. All mining operations involve the production of waste. Many regard such waste (tailings) and their environmentally acceptable storage as constituting the largest waste problem on Earth because of the enormous damage and loss-of-life that have resulted from failures of tailings storage facilities. This project focuses on a dewatering technology, electro-osmosis (EO), which has yet to be fully operationalised, for improvin ....Accelerating Consolidation and Closure of Mine Tailings Storage Facilities. All mining operations involve the production of waste. Many regard such waste (tailings) and their environmentally acceptable storage as constituting the largest waste problem on Earth because of the enormous damage and loss-of-life that have resulted from failures of tailings storage facilities. This project focuses on a dewatering technology, electro-osmosis (EO), which has yet to be fully operationalised, for improving the strength, stability and settlement characteristics of the tailings. Sophisticated testing will be undertaken at three scales (lab, meso and, most importantly, field), as well as the development of generic numerical models, to create practical guidelines to facilitate the implementation of EO in mines around the world.Read moreRead less
Measuring the benefits of reuse in the circular economy. The project will advance understanding of reuse commodity chains, their societal benefits and contributions to a more sustainable circular economy. Drawing on case study research with charitable and community reuse organisations, factors facilitating or inhibiting reuse will be identified, and rigorous methods developed for assessing the benefits of reuse organisations in terms of quantities of materials processed, employment, skills devel ....Measuring the benefits of reuse in the circular economy. The project will advance understanding of reuse commodity chains, their societal benefits and contributions to a more sustainable circular economy. Drawing on case study research with charitable and community reuse organisations, factors facilitating or inhibiting reuse will be identified, and rigorous methods developed for assessing the benefits of reuse organisations in terms of quantities of materials processed, employment, skills development and contributions to regional economic development. Research outputs will provide a sound evidence base for government policy and decision-making and strengthen conceptual understanding of drivers and enablers of reuse and links with broader economic activities.

Reducing the deleterious impacts of clay particle interactions with valuable minerals in copper and gold processing. This project seeks to understand the rheological behaviour of clay minerals and the effect of the viscosity caused by clay minerals on gas dispersion, the transport of network structures and the locking of the structures in the froth in mineral flotation. Novel methods will be developed to improve flotation separation by reducing the viscosity.
