The mining industry is processing low-grade ores associated with high amounts of waste minerals. Extracting metals from low-grade ores is very difficult with technical challenges in rejecting waste minerals. This project aims to understand the surface properties and the behaviour of a major waste mineral which is becoming increasingly problematic during the processing of copper and gold ores. New chemistry and chemical reagents will be developed to efficiently and economically reject the waste mineral by manipulating the reactions that take place on its surface. This project expects to have immediate economic and environmental impacts through increasing metal production, cutting greenhouse gas emissions and applying new green reagents.

采矿业正在加工与大量废矿物相关的低品位矿石。从低品位矿石中提取金属非常困难，在剔除废矿物方面存在技术挑战。该项目旨在了解主要废矿物的表面特性和行为，这种矿物在铜和金矿石加工过程中变得越来越成问题。将开发新的化学和化学试剂，通过操纵其表面发生的反应，有效且经济地去除废矿物。该项目预计将通过增加金属产量、减少温室气体排放和应用新型绿色试剂产生直接的经济和环境影响。
