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.

该项目旨在探讨如何在通过碳固存进行矿石加工的背景下利用在地球科学中产生深远影响的反应诱导孔隙度和溶解-再沉淀反应耦合概念。该项目的主要成果是产生一种新的工艺，保持矿石中的孔隙度，以及浸出剂的组合，以实现有效的铜金属回收和铁捕获。该项目将为矿业提供一种替代方案，以取代目前需要破坏矿物承载经济价值的铜矿物加工模式，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。
