摘要/Abstract

摘要：

由于金在含碳矿石中的含量很低,根据矿样的性质采用预处理、溶解、分离、富集和测定的方法。针对湖南东安新龙矿业有限公司含碳矿石,选择浓硫酸+浓硝酸+氯酸钾试剂对样品进行预处理,再加王水分解矿样,最后用硫代米蚩酮分光光度法测定金。与其它测定方法进行比较,使用该方法进行金的分析测定得到了较为满意的结果。

Abstract:

Because of low gold content in ore, the methods of p retreatment, samp le dissolution, separation, enrichment and determination should be adop ted according to the characters of the ore samp les to find the gold out. Aiming t analyzing the gold in the ores of Hunan XinlongMining Co. , L td. in Dongan, we choose the oil of vitriol, concentrated nitric acid, and potassium chlorate to p retreat the samp les, then add aqua regia to decompose them, finally,use thiomichlers ketone spectrophotometry to determinate gold. We can find that the method introduces in this paper is
superior to the others by comparison.
