为了使地质地球化学样品测定的组分,尽量均匀地分布在制备的样品中,获得测定元素的正确结果,制样的质量(磨样过程原料的分布状态)具有重大的意义.含金矿石在制样过程中可能出现不均匀现象——脉石组分与金的分异现象,这是因为金的物理—化学性质与样品中其他组分有明显的差别.这个问题的迫切性,是由于分析方法的迅速发展所决定的,这些方法的特点是重现性好,分析时的用样量小(一克或更少),因此,金的分布不均匀,常常影响分析结果.以往我们对这个问题作过某些探讨.本文的目的是在于研究具有不同地质地 In order to make the components of the geo-geochemical samples distributed as evenly as possible in the prepared samples and obtain the correct result of the determination of the elements, the quality of the samples (the distribution state of the raw material in the grinding process) is of great significance. Unevenness may occur in the process of sample preparation - the segregation of gangue components from gold because the physical-chemical properties of gold differ significantly from the other components of the sample. The urgency of this problem is due to Due to the rapid development of analytical methods, these methods are characterized by good reproducibility and small sample size (one gram or less) when analyzed, so that the distribution of gold is not uniform and often affects the analysis results. This issue has been discussed in some ways.The purpose of this paper is to study the different geology
