     A Study on Electrochemical Corrosion of Surface Reaction of Pyrite in High Alkali Environment
     高碱环境中黄铁矿表面反应的腐蚀电化学研究
短句来源
     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.
