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
Mitigation of nitrogen oxides (NOx) formed in blasting of ammonium nitrate explosives. Several mines in Australia experience the formation of orange-brown fumes containing nitrogen oxide (NOx) gases, immediately after blasting of ammonium nitrate (AN) explosives to crush the rock. This project develops new explosives technologies, aimed to mitigate the formation of post-blast fumes, that are safe to people and the environment.
Improved control of dioxin emissions during iron ore sintering. This project aims to develop an innovative assessment of dioxin formation through analysis and speciation of its precursors (Cl and Cu). Iron ore sintering is the industrial process with the highest emissions of dioxins and furans to the environment in Australia, which are amongst the most toxic substances produced by man. The aim of this project is to conduct critical investigations required for control of dioxin emissions during i ....Improved control of dioxin emissions during iron ore sintering. This project aims to develop an innovative assessment of dioxin formation through analysis and speciation of its precursors (Cl and Cu). Iron ore sintering is the industrial process with the highest emissions of dioxins and furans to the environment in Australia, which are amongst the most toxic substances produced by man. The aim of this project is to conduct critical investigations required for control of dioxin emissions during iron ore sintering. The expected outcome of this project is the development of control mechanisms for the process conditions responsible for dioxin formation. This should provide significant benefits, such as assisting the Australian iron ore industry to address the environmental requirements of their international trade partners and sustain their iron ore exports.Read moreRead less

Evidence suggests that collaboration in the workplace and high involvement approaches have a productivity premium of up to 20 per cent over those without the commitment to collaborative approaches. However, collective relations do not necessarily mean union relations nor necessarily collaborative relations. This research will benefit Australia's social and economic fabric through understanding alternative means by which collaborative workplace relations lead to productivity gains. This is consistent with the current policy approach of government in promoting productive and harmonious workplace level industrial relations.Read moreRead less
