吸附电提取技术野外实验研究

吸附电提取是我国独创的对隐伏金属矿床和贵金属矿床普查找矿的重要技术方法。本研究利用对Au3 + 具有极强的吸附能力的活化高密聚醚型聚氨脂泡塑制成的石墨电极在山东省五莲县七宝山金矿进行吸附电提取野外实验研究。实验表明 ,本区吸附电提取背景值为33.39ng ,最高异常值达18280ng ,最大异常的平均值为3406ng ,最高富集系数为547 ,平均富集系数为102 ,用常规原子吸收光谱分析就能满足要求。本技术方法是隐伏矿床普查找矿的有效技术方法之一。

FIELD ABSORPTION-ELECTRICITY EXTRACTION EXPERIMENTS

Absorption-electricity extraction is an important technique,which is originally created by China and used to reconnaissance survey and prospecting for concealed metallic and precious metal deposits.Using graphite electrode which is of extreme strong absorbability and made of activated polyurethane foamed plastics,the authors made field absorption-electricity extraction experiments in the Qibaoshan gold deposit,Wulian County,Shandong Province.The results show that the background value of absorption-electricity extraction in the area is 33.39 ng,the highest abnormal value is up to 18 280 ng,the largest abnormal average value is 3 406 ng,the highest enrichment coefficient is 547,the average coefficient is 102,and conventional atom absorption spectrum analysis can meet experimental demands.This technique is an effective method of reconnaissance survey and prospecting.
