摘　　要：通过在吉林红旗岭铜、镍矿区开展研究,在铜、镍矿体上同步垂直出现了Cu、Ni、Co、Pt、Cr、Sr异常。异常值的高低排列顺序是Cu>Ni>Co Pt>Cr>Sr,呈明显的电化学异常标志。对铜、镍矿的电化学溶解试验研究的结果表明,当铜、镍矿标本电解到24h,其溶液中的Cu2+、Ni2+、Co2+离子质量分数分别达到2.2×10-6、1.8×10-6、1.5×10-6,充分证明铜镍矿床不但能产生电化学溶解,而且电化学溶解能力较强。经过在吉林红旗岭矿区深部找矿预测,发现3处具有成矿远景的地电化学异常,表明该方法具有良好的找矿效果。By the method of the geo-electrochemical extraction, the authors carried a series of experiments in the Hongqiling copper-nickel deposit, Jilin Province. The geo-electrochemical anomalies of Cu, Ni, Co, Pt, Cr and Sr have been observed on the ore body with an order of Cu>Ni>CoPt>Cr>Sr. The electrochemical experiments on nickel-copper ores reveal 2.2×10^(-6) of Cu^(2+),1.8×10^(-6 )of Ni^(2+),1.5×10^(-6) of Co^(2+) in the solution after 25 hour dissolving of copper-nickel ore, indicating intense electro chemical dissolution in the copper-nickel ores. Three geo-electrochemical anomalies have been found at the depth of the Hongqiling copper-nickel deposit and have been proven to be prospective, illustrating the efficiency and reliability of the method.
