摘　　要：采用三电极体系,以黄铜矿、辉铜矿、铜蓝悬浮矿浆为对象,研究浸出过程的电化学行为。结果表明,辉铜矿较易发生氧化,而黄铜矿最难。黄铜矿在氧化浸出过程中生成铜蓝中间产物,辉铜矿也转化为铜蓝再进行浸出。The electrochemical behavior of sulfide copper minerals in leaching process is investigated with suspending slurry of chalcopyrite, chalcocite and covellite by the three-electrode system. The results show that Cu2S is the easiest one to be oxidized, CuFeS2 is the most difficult one in three minerals. CuS appears as the intermediate product in Cu2S and CuFeS2 leaching process.
