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.

矿产工业是澳大利亚最大的出口行业，约占澳大利亚总出口的40%。研磨是矿物加工中从母岩中释放有价值物质的基本操作之一。然而，磨矿过程的效率非常低，可能占选矿厂直接运营成本的 50%。该项目旨在开发一种新颖的多尺度模型，以研究工艺和单个颗粒水平上的研磨，并提供更准确的研磨性能预测。这将改善研磨过程的控制和设计，减少能源消耗和矿物废物，这将为澳大利亚带来巨大的经济和环境效益。
