测定化探样品中金的一种无排放溶矿法

岩矿测试中王水湿法溶解是目前普遍采用的测金分解方法。随着化探扫面工作的开展,金的分析剧增,沿用的分解方法对环境污染和对分析人员健康的危害已日益严重。

A NON-ESCAPE MINERAL DISSOLUTION METHOD FORDETERMINATION OF GOLD IN SAMPLES

Asimple, enclosed device for sample dissolution under normal pressure is suggested in this paper. It eliminates the dissolved components of aqua regia produced in the process so as to protect the health of the analysts and to avoid environment pollution. This method has been used in the pilot determination of trace gold in various types of ores and other materials, and the results are compared and proven to be satisfactory.
