This project aims to understand the reactions taking place on the major gangue (waste) mineral during the recovery of base-metal and precious minerals. The mining industry is processing low grade complex ores and experiencing difficulties in rejecting gangue minerals in mineral separation and metal extraction plants. The project will develop new technologies that manipulate these reactions to achieve mineral separation and metal extraction efficiently and economically. These technologies may provide value in processing low quality complex polymetallic resources using low quality water, whilst halving the operating costs of mineral concentrators and providing corresponding reductions in harmful emissions.

该项目旨在了解基本金属和贵重矿物回收过程中主要脉石（废）矿物发生的反应。采矿业正在加工低品位复杂矿石，并且在矿物分离和金属提取工厂中剔除脉石矿物方面遇到困难。该项目将开发操纵这些反应的新技术，以高效、经济地实现矿物分离和金属提取。这些技术可以为使用低质量水处理低质量复杂多金属资源提供价值，同时将选矿厂的运营成本减半，并相应减少有害排放。
