美国用旋转圆盘电极循环伏安法和接触角测定 ,研究了ＳＯ2 对于黄铜矿无捕收剂浮选和捕收剂引起的浮选影响机理。黄铜矿氧化的第一步是析出铁 ,它水解后可留在表面 ,使表面亲水。在搅拌的溶液中 ,大量铁进入溶液中 ,使Ｃｕ Ｓ层比原来的黄铜矿或复盖铁的表面更容易与捕收剂作用 In the United States, cyclic voltammetry and contact angle measurements of rotating disk electrodes were used to investigate the mechanism of SO2 flotation caused by flotation and collector-free cataplasm of chalcopyrite. The first step in chalcopyrite oxidation is precipitation of iron, which can remain on the surface after hydrolysis, rendering the surface hydrophilic. In the stirred solution, a large amount of iron enters the solution, making the CuS layer easier to interact with the collector than the original chalcopyrite or iron-covered surface
