摘要：
Rest potential and linear potential sweep techniques were used to study the cathodic-polarization processes on chalcopyrite, simulating chalcopyrite short-circuited with grinding media in a wet grinding mill. Microflotation tests were carried out to investigate the effect of cathodic polarization on the collectorless flotation of chalcopyrite. It was observed that collectorless flotation of a cathodically polarized chalcopyrite sample could he obtained when oxygen was used for aeration, but not if nitrogen was used. A mechanism for the role that oxygen plays in the collectorless flotation of cathodically polarized chalcopyrite is discussed.
