【Abstract】 Surface corrosion behaviors of pyrite are studied using electrochemical corrosion technology in high alkali environment. The results show that at high pH values, with increasing pyrite’s surface resistance, pyrite’s corrosion is controlled, preventing further oxidation reduction from occurring. This is the reason why pyrite is depressed in high alkali pulp.更多还原
