Abstract
This study examines the role complexing agents play in pentlandite-pyroxene flotation and focuses on the surface chemistry and interaction between valuable and gangue minerals as well as the interaction of complexing agents and reagents (xanthate, copper sulphate) in the system at pH 9. Microflotation, zeta potential measurements, ToF-SIMS analyses (time of flight secondary ion mass spectrometry) and X-ray photoelectron spectroscopy (XPS) were used as tools in determining the extent of surface alteration.
