矿石中金的分析较其它元素分析重现性差。其原因有两方面:第一是由于矿石中自然金含量低、比重大、延展性强,经加工后样品的均匀性差。第二是分析过程中存在问题,如分析取样量、样品焙烧、分离富集、测定方法等。我们对这些因素做了较系统的实验研究,发现了一些问题。样品焙烧就是金矿分析(湿法)中的重要问题之一,本文对此做一初步探讨。 Analysis of gold ore than other elements of poor reproducibility. There are two reasons: The first is due to the natural gold ore content is low, the proportion of large, ductile, processed samples poor uniformity. The second is the analysis of the problems, such as analysis of sample volume, sample roasting, separation and enrichment, determination methods. We conducted a more systematic experimental study of these factors and found some problems. Sample roasting is one of the important problems in gold analysis (wet method). This article makes a preliminary study on this.
