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.

澳大利亚采矿和矿产加工行业在2004/5年度产生了约560亿美元的出口，占澳大利亚总出口的约44％。研磨是一项基本操作，将有价值的矿物从主机岩中解放出来。但是，常规的研磨技术非常低效。新开发的ISAMILL技术大大提高了研磨过程的功率效率。 该项目旨在通过合并的实验和数值研究来了解Isamill中颗粒和流体的流动，从而改善了磨削性能并降低能耗。这项工作将不仅为Xstrata和澳大利亚矿产加工业带来重大的经济利益。
