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.

该项目旨在了解岩石环境中控制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都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。矿床的形成受矿物溶解和结晶的物理化学作用以及流体流经多孔岩石和裂隙的影响。该项目整合了地质学、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，从而提高原位采矿和浸出技术的效率。所产生的知识可以应用于改善矿产勘探、开采和加工，有助于解锁低品位、矿物复杂的矿石中价值数十亿美元的资源。
