中国矿山工程

One copper mine in Shanxi Province is used as an example, where chalcocite and associated minerals of pyrite are main components and can't be separated by traditional xanthate flotation method. Therefore, electrochemical separation is adopted, and the Tafel curve is used to analyze the change in crystal structure of copper powder during separation. The optimum temperature and pH value for separation are obtained from tests with a single variable, and the potentiostatic test is used to find out the reaction mechanism of electrochemical separation for copper mine, so as to provide the first-hand information for production in the future.
