1.化探找金矿,颇有成效。测定样品中的金是寻找金矿最好的指示元素。要求测金方法的灵敏度达0.1ppb。为此中国有色金属工业总公司桂林矿产地质研究院分析室最近两年内对微金的测定做了一些研究工作,建立了几种方法。其中“化学—光谱测定金”的方法做得较好。灵敏度达0.03ppb,工效、成本和准确度均能满足生产上的要求。有色地质系统化验部门对此方法颇感兴趣,有几个化验室想引进此方法。现在已与河南有色地勘公司达成技术转让协议。 Geochemical exploration of gold, quite fruitful. Determining the gold in the sample is the best indicator of finding gold. Requires gold method sensitivity of 0.1ppb. To this end China National Nonferrous Metals Industry Corporation Guilin Institute of Mineral Geology Institute of the last two years on the determination of micro-gold to do some research work, the establishment of several methods. Among them, the method of “chemical-spectrometry gold” did a good job. Sensitivity of 0.03ppb, ergonomics, cost and accuracy can meet the production requirements. There is a lot of interest in this method from the Laboratory of Nonferrous Geological Systematics, and several laboratories would like to introduce this method. Henan Nonferrous Geological Prospecting Company has now reached a technology transfer agreement.
