Depressing pyrrhotite in copper and gold flotation (2021–2024)
Abstract:
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.
