Abstract
In this study, pulp aeration/oxidation potential is used to optimise the selective flotation of chalcopyrite from pyrite through a combination of single mineral, mixed minerals and real ore flotation experiments. The consumption of oxygen method was used as a tool for measuring and estimating the pyrite (and chalcopyrite) mineral reactivity and susceptibility to oxidation. The various reactions occurring at the minerals surface were also investigated using surface analytical techniques such as ethylene diamine-tetra acid (EDTA) extraction, X-ray photoelectron spectroscopy (XPS) and time-of-flight secondary ion mass spectrometry (ToF-SIMS).
