@@1 IntroductionThis research is mainly concerned with a study of CHIM- geoelectrochemical method for prospecting Cu-Ni deposits in China.Included in the experiments were electrochemical dissolution tests.As a result of our experiments, we concluded that natural or artificial electric field enables the Cu-Ni ore dissolving Cu2+, Ni2- and other cations which can be moved and richen on the surface in the effects of external electric field, which is the halo-forming of the Cu-Ni deposit. On the basis of it,the feasible experiments about geo-electrochemical methods for prospecting research were carried out in Jilin Hongqiling and Jinchuan Cu-Ni deposits.The results of the experiments have shown that some clear geo-electrochemical anomaly are tested on the section of the known ore bodies.It was indicated that geo-electrochemical methods for prospecting these types of concealed Cu-Ni deposit was effective.From the experiments,we forecasted several electrochemical abnormal targets in external and deepper areas of the two deposits by geo-electrochimestry methods.
