The Australian Research Data Commons (ARDC) invites you to participate in a short survey about your
interaction with the ARDC and use of our national research infrastructure and services. The survey will take
approximately 5 minutes and is anonymous. It’s open to anyone who uses our digital research infrastructure
services including Reasearch Link Australia.
We will use the information you provide to improve the national research infrastructure and services we
deliver and to report on user satisfaction to the Australian Government’s National Collaborative Research
Infrastructure Strategy (NCRIS) program.
Please take a few minutes to provide your input. The survey closes COB Friday 29 May 2026.

Practical Application of Filtration Theory to the Minerals Industry. The project aims to provide a quantitative basis for the selection, design, operation and maintenance of filter devices in the minerals industry. This will be achieved through characterisation of materials to be filtered by developing a model of the true role of the membrane in filtration. Experimental parameters will be input to first principles filtration models. This will reduce the incidence of poor operational outcomes ....Practical Application of Filtration Theory to the Minerals Industry.

This will be achieved through characterisation of materials to be filtered by developing a model of the true role of the membrane in filtration. Experimental parameters will be input to first principles filtration models. This will reduce the incidence of poor operational outcomes for filter presses and provide a sound basis for the maintenance of filter cloths and membranes.Read moreRead less
Impact of recycled and low quality process water on sustainable mineral processing practices. Water is in short supply and needs to be considered as a 'key reagent'. The quality of this reagent can vary widely. For a sustainable mineral processing practice, the use of recycled or low quality/saline process water will be essential for a plant to operate in the future. The major benefit is recognition that significant recycle of process water for flotation is achievable if simple water quality con ....Impact of recycled and low quality process water on sustainable mineral processing practices. Water is in short supply and needs to be considered as a 'key reagent'. The quality of this reagent can vary widely. For a sustainable mineral processing practice, the use of recycled or low quality/saline process water will be essential for a plant to operate in the future. The major benefit is recognition that significant recycle of process water for flotation is achievable if simple water quality control and management practices are implemented. In addition, a better understanding and control of water quality in recycled/saline process water may lead to improved flotation stability and performance, and reduced reagent consumption.Read moreRead less
BEACH FORMATION OF NON-SEGREGATING TAILINGS. Thickened tailings from mining operations discharged onto flat ground build into a low conical hill, forming a straight beach slope. This method of stacked tailings disposal is currently employed at nine Australian mine-sites. It is cost effective and environmentally friendly. Discharged thickened pastes can develop steeper slopes, thus requiring less area for the tailings stack. However, a tailing discharge system design must be based on an accurate ....BEACH FORMATION OF NON-SEGREGATING TAILINGS. Thickened tailings from mining operations discharged onto flat ground build into a low conical hill, forming a straight beach slope. This method of stacked tailings disposal is currently employed at nine Australian mine-sites. It is cost effective and environmentally friendly. Discharged thickened pastes can develop steeper slopes, thus requiring less area for the tailings stack. However, a tailing discharge system design must be based on an accurate prediction of the beach slope. The aim is to produce a method of predicting the beach slope angle from laboratory experiments involving particle mechanics, rheology, and process parameters like flowrate and concentration.Read moreRead less
Thickener operation optimisation and design for the minerals industry. Thickening is the main process used in the minerals industry for recovery and recycling of water and the environmental management of waste products. This project will provide simple but fundamental experimental and modelling tools to enhance thickener design and operations.

Thickening is the main process used in the minerals industry for recovery and recycling of water and the environmental management of waste products. This project will provide simple but fundamental experimental and modelling tools to enhance thickener design and operations. The result will be improved water recovery, reduced waste volumes, environmentally sustainable options for waste tailings disposal and significant cost reductions through improved device design at a large number of sites both in Australia and overseas. An additional benefit will be an integrated design and operational approach to thickener utilisation in the minerals industry.Read moreRead less
Particle transport in turbulent non-Newtonian suspensions in self formed open channels. An improved understanding of the fundamentals of channel formation and the ability of channels to transport solids in either a natural or created environment will be of benefit to industries employing open channels (or flumes) or stacked tailings as part of their processes. This will lead to better design and operation with reduced water use and reduced volume of waste disposal. This research will build the ....Particle transport in turbulent non-Newtonian suspensions in self formed open channels. An improved understanding of the fundamentals of channel formation and the ability of channels to transport solids in either a natural or created environment will be of benefit to industries employing open channels (or flumes) or stacked tailings as part of their processes. This will lead to better design and operation with reduced water use and reduced volume of waste disposal. This research will build the scientific foundation for the design tools to more accurately predict the behaviour of tailings stacks. The mining industry will benefit from the improved management of their tailings disposal regimes, reduced water usage, lowered cost of disposal and reduced impact on the environment.Read moreRead less
Thickener dewatering optimization in the minerals industry. The project aims to develop the understanding required to provide a quantitative basis for the selection, design and operation of thickening devices for optimal dewatering performance in the minerals industry.

The project aims to develop the understanding required to provide a quantitative basis for the selection, design and operation of thickening devices for optimal dewatering performance in the minerals industry. This will enable reduced water use, improved water management, provide better slurry solids management and improve tailing disposal practice, resulting in reduced processing and capital costs, increased throughput and lower environmental impact. In particular, the project will link the characterisation of the slurry feed to thickener process conditions and subsequent dewatering performance, including the role of rakes and shear devices. It will provide a sound basis for the optimization of dewatering in thickener operations.Read moreRead less
