This project aims to reduce risk in the mining industry from failing mine tailings by producing a methodology for predicting the susceptibility of these tailings to static liquefaction. The impact of a mine tailing failure is catastrophic to the downstream community. The project brings together a number of industry partners committed to assisting with verification and adoption of characterisation and designed tools development in this project. This proposal will integrate results from laboratory element, centrifuge and calibration chamber tests with numerical modelling and in-situ tests to produce a methodology for predicting the susceptibility to static liquefaction.Read moreRead less

This project aims to systematically investigate a proof-of-concept engineering process for transforming mine waste into value. The research will develop and employ state-of-the-art tools to advance our knowledge of efficiently sequestering carbon dioxide using ultramafic nickel mine tailings, while also enabling the extraction of critical metals—particularly nickel—and the production of value-added products, such as high-purity magnesium carbonate hydrate and silica. Successful outcomes from this research will provide benefits for mitigating global warming, supplying critical metals for renewable energy technologies, and facilitating the transition of Australia's mining industry towards sustainability.Read moreRead less
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
Accelerated tailings remediation with plant and microbial biotechnologies. The Australian alumina industry produces 32 million tonnes of bauxite residue (alumina refining tailings) each year, most of which is stored in perpetuity in landfill-type tailings storage facilities. The high pH, high salinity, lack of plant nutrients, and poor physical properties of bauxite residue are major barriers to safe storage and successful closure of tailings storage facilities. Existing remediation approaches a ....Accelerated tailings remediation with plant and microbial biotechnologies. The Australian alumina industry produces 32 million tonnes of bauxite residue (alumina refining tailings) each year, most of which is stored in perpetuity in landfill-type tailings storage facilities. The high pH, high salinity, lack of plant nutrients, and poor physical properties of bauxite residue are major barriers to safe storage and successful closure of tailings storage facilities. Existing remediation approaches are expensive, slow, and often ineffective. We will deliver new microbial- and plant-driven biotechnologies for rapid, cost-effective remediation of bauxite residue. This will enable safe, sustainable closure of storage facilities, and safeguard the strong contribution of this $15 billion industry to Australia's economy. Read moreRead less
Differential solidification of steel slag to create a fertiliser co-product. The project aims to develop a process to separate phosphorus from steelmaking slag while the slag is still molten. Changing iron ore grades in Australia, especially increasing phosphorus content, places Australian iron ore products at a competitive disadvantage and attracts a significant financial penalty. The separation process is intended to facilitate recycling of an iron rich stream within the steelworks and product ....Differential solidification of steel slag to create a fertiliser co-product. The project aims to develop a process to separate phosphorus from steelmaking slag while the slag is still molten. Changing iron ore grades in Australia, especially increasing phosphorus content, places Australian iron ore products at a competitive disadvantage and attracts a significant financial penalty. The separation process is intended to facilitate recycling of an iron rich stream within the steelworks and production of a phosphorus rich co-product for agriculture. Benefits are anticipated to include increased utilisation of steel slag, creation of a valuable fertiliser co-product, decreased greenhouse gas emissions, and a reduction in the penalty applied to Australian iron ores.Read moreRead less
Regeneration of High Value-Added Materials from Spent Lithium-Ion Batteries. This project aims to develop scalable processing techniques for the regeneration of cathode materials and the production of high-purity alumina and graphene from spent lithium-ion batteries. The techniques reduce the cost and time of the processing of degraded cathode materials and increase the value of the spent battery materials (e.g., metallic aluminum and graphite) by converting them into high value-added specialty ....Regeneration of High Value-Added Materials from Spent Lithium-Ion Batteries.

The techniques reduce the cost and time of the processing of degraded cathode materials and increase the value of the spent battery materials (e.g., metallic aluminum and graphite) by converting them into high value-added specialty chemicals. The outcomes and further technology adoptions will extend the capacity of the Partner Organisation for producing specialty battery materials. The outcomes could help Australia’s battery industry switch to a more diversified pathway, which benefits the economic development of Australia in a long term.Read moreRead less
In-situ catalytic upgrading of bio-oil using scrap tyre char. This project aims to develop advanced, cost-competitive catalysts based on scrap tyre char, an otherwise low-value by-product.

Economically efficient green logistics through cyber physical systems. This project aims to realize green logistics by researching how to run diesel-powered heavy-duty milk trucks economically and efficiently on liquefied natural gas (LNG) and demonstrating to logistics companies that LNG conversion will reduce operating costs and emissions. Transportation systems account for 18% of Australia's carbon emissions, and diesel-powered logistics vehicles are a major contributor. However, converting these trucks to LNG requires strong evidence to convince logistics companies of the benefits of shifting to green logistics. An increase in logistics productivity is expected to increase Australia’s gross domestic product by $2 billion, while this research should also provide vital data on sustainability issues and LNG conversions.Read moreRead less
Life in the Shipping Lane; The Cost of Increasing Disturbance to Whales. This project aims to quantify the increasing risk of ship strike to humpback whales in Moreton Bay, and predict the impact of chronic disturbance to nursing calves.

This project aims to quantify the increasing risk of ship strike to humpback whales in Moreton Bay, and predict the impact of chronic disturbance to nursing calves. The research builds on pilot findings identifying Moreton Bay as a resting area for migrating humpback whales. Using empirical and modelling approaches, this research responds directly to the Federal Government strategy for mitigating ship strike, which explicitly flags Moreton Bay as an 'area of concern'. The project has been developed in collaboration with traditional owners and industry, and is expected deliver optimal mitigation measures for the region. Findings further carry implications for similar functional habitats along Australia's humpback whale migratory corridors.Read moreRead less
