摘要
从金和黄铁矿在不同性质溶液中的电极电位与稳定电位出发,研究了金与黄铁矿所组成的原电池中有关电化学作用,探讨了隐伏金矿金离子晕的形成机理。结果表明:金矿的电化学溶解是金离子的主要来源;提取电极正负极同时使用或交叉使用,可提高地电提取法找金的有效性;用时量曲线可区分矿致异常与非矿异常。
Based on electrode potentials and stable potentials of gold and pyrite indifferent solutions, the paper deals with the formation mechanism of goldion halos in hidden gold deposits and discusses electrochemistry of theprimary cells composed of gold and pyrite. The results show that gold ionsare mainly derived from electrochemical dissolution of gold deposits. Theextraction electrodes of both anode and cathode are used at the same time orone by one in turn to improving the efficiency of gold prospecting duringgeoelectrochemical extraction. The anomalies related to mineralization may beseparated from thoseun related to mineralization by using time-capacity curves.
