Depressing pyrrhotite in copper and gold flotation

采矿业正在加工与大量废矿物有关的低品位矿石。从低品位矿石中提取金属是非常困难的，在废弃矿物中存在技术挑战。该项目旨在了解一种主要废矿物的表面特性和行为，这种矿物在铜和金矿的加工过程中变得越来越成问题。人们将开发新的化学试剂，通过控制矿物表面发生的反应，有效而经济地处理废矿物。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的绿色试剂，产生立竿见影的经济和环境影响。

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.
