This project aims to understand the chemical and physical processes that govern reactive transport and metal scavenging in rocky environments. Much of Australia's mineral wealth is the result of the interaction of warm fluids with rocks deep in the Earth over geological timescales. The formation of ore deposits is governed by the physical chemistry of mineral dissolution and crystallisation, and by fluid flow through porous rocks and fractures. This project integrates innovation in geology, chemistry, and mineral engineering, and will deliver mineral-scale reaction models that will increase efficiency of in-situ mining and leaching technologies. Knowledge generated can be applied to improve mineral exploration, mining, and processing, contributing to unlocking billions of dollars’ worth of resources tied up in low grade, mineralogically complex ores.

该项目旨在了解控制岩石环境中的反应运输和金属清除的化学和物理过程，澳大利亚的大部分矿产资源是在地质时间尺度上温暖的流体与地球深处的岩石相互作用的结果。受矿物溶解和结晶的物理化学以及穿过多孔岩石和裂缝的流体流动的控制。该项目集成了地质学、化学和矿物工程方面的创新，并将提供矿物规模的反应模型，从而提高效率。现场采矿和浸出技术所产生的知识可用于改善矿物勘探、采矿和加工，有助于释放低品位、矿物学复杂的矿石中价值数十亿美元的资源。
