This project aims to explore how the concepts of reaction-induced porosity and coupled dissolution-reprecipitation reactions, which have had a profound impact in geosciences, can be exploited in the context of ore processing through carbon sequestration. The project's main outcomes are to generate a new process that maintains porosity in ore, and a combination of lixiviants, for effective Cu metal recovery and Fe capture. This project will benefit the mineral industry by providing an alternative to the current paradigm in Copper mineral processing that requires the destruction of the mineral hosting economic value, thereby developing sustainable mining technologies well suited for the increasingly complex ores being extracted in Australia.

该项目旨在探索如何在碳封存矿石加工的背景下利用反应诱导孔隙度和耦合溶解-再沉淀反应的概念，这些概念对地球科学产生了深远的影响。该项目的主要成果是开发一种可保持矿石孔隙度的新工艺，并结合浸出剂，以实现有效的铜金属回收和铁捕获。该项目将为当前的铜矿物加工模式提供一种替代方案，从而使采矿业受益，这种模式需要破坏具有经济价值的矿物，从而开发出非常适合澳大利亚开采的日益复杂的矿石的可持续采矿技术。
