Fundamental investigation of particle-fluid flow in the IsaMill grinding process. The Australian mining and minerals processing industries generated exports of about $56 billion in 2004/5, representing approximately 44 per cent of Australia's total exports. Grinding is a basic operation that liberates valuable minerals from the host rock. However, conventional grinding technologies are very inefficient.

The Australian mining and minerals processing industries generated exports of about $56 billion in 2004/5, representing approximately 44 per cent of Australia's total exports. Grinding is a basic operation that liberates valuable minerals from the host rock. However, conventional grinding technologies are very inefficient. The newly developed IsaMill technique greatly improves the power efficiency of the grinding process. This project aims to understand the flow of particles and fluids within IsaMill through combined experimental and numerical studies, leading to improved grinding performance and lower energy consumption. Such work will provide a significant economic benefit not only to Xstrata but also to the Australian mineral processing industry.Read moreRead less

The advanced machine guidance and monitoring technology developed by this project will significantly enhance the partner organisation's capacity as a leading supplier of mining machine control systems. The deployment of such enhanced machine control systems will offer an immediate national benefit to the Australian Mining Industry by dramatically improving productivity and occupational safety. The national interest will also be served by this project's significant contribution to Australia's leadership position as an innovator in frontier technologies for mining and robotics. Furthermore, the research outcomes will help to solve similar positioning problems in hazardous, GPS-denied environments such as urban search and rescue.Read moreRead less
Multi-scale modelling of particle breakage in grinding process. The minerals industry is the largest exporter in Australia, contributing approximately 40% of Australia's total exports. Grinding is one of basic operations in mineral processing to liberate valuables from the host rock. Grinding process, however, has very low efficiency and may account for 50% of the direct operating cost of a mineral processing plant. This project is to develop a novel, multi-scale model to investigate grinding at ....Multi-scale modelling of particle breakage in grinding process. The minerals industry is the largest exporter in Australia, contributing approximately 40% of Australia's total exports. Grinding is one of basic operations in mineral processing to liberate valuables from the host rock. Grinding process, however, has very low efficiency and may account for 50% of the direct operating cost of a mineral processing plant. This project is to develop a novel, multi-scale model to investigate grinding at both process and individual particle levels and to provide a more accurate prediction of grinding performance. This will result in improved control and design of grinding process with reduced energy consumption and mineral waste, which will be of immense economic and environmental benefit to Australia.Read moreRead less
A Mathematical Approach to Flexible Management of Open Pit Mines with Uncertain Geology and Unpredictable Demand. This project will create new mathematical algorithms to flexibly manage open pit mining projects. The development of strategic plans for mining operations is a highly complex task, based on incomplete geological information and uncertain future commodity demand. The smart mathematics we create will allow Australia to capitalise on upturns in international demand, while limiting unavo ....A Mathematical Approach to Flexible Management of Open Pit Mines with Uncertain Geology and Unpredictable Demand. This project will create new mathematical algorithms to flexibly manage open pit mining projects. The development of strategic plans for mining operations is a highly complex task, based on incomplete geological information and uncertain future commodity demand. The smart mathematics we create will allow Australia to capitalise on upturns in international demand, while limiting unavoidable negative outcomes, by flexibly adjusting the mining operation to prevailing geological and economic conditions. Australia's mineral exports are worth over $50b annually to the Australian economy. Our techniques will better manage Australia's mining projects and capture new, emerging markets, significantly impacting on Australia's balance of trade.Read moreRead less
