摘要：
Electrochemical measurements were made using chalcopyrite and pyrrhotite electrodes in aqueous solutions containing a xanthate collector and ground ore mineral particles. The purpose was to investigate the electrochemical reactivity of ozone with respect to dissolved xanthate, surface adsorbed xanthate, and the sulfide mineral itself. Electrochemical evidence for the removal of xanthate coatings from chalcopyrite, pyrrhotite, and platinum surfaces by ozone is presented. The oxidizing power of ozone is compared with that of oxygen and other common oxidizing agents to portray the superiority of ozone as an oxidant.
