近年来,许多冶金地质化探单位,在做金的分析时,遇到的一个突出问题是,野外供样量少、试样中金含量分布不匀与要求测定的金量极痕的矛盾.因此,如何能使金的地球化学试样的采集量、试样制备与基本满足测定要求的分析试样量三者合理的统一,乃是当前金的化探分析工作中亟待解决的问题. 在十多年前,当国外正大力开展金的地球化学勘查时,也曾遇到上述问题.有些化探工作者,对此进行调查、试验并作了报道,普遍认为金的化探试样采集重量、试样制备,以及送实验室试样的粒度与重量,是影响化探找金时合理评价的
In recent years, many metallurgical geochemical exploration unit, doing gold analysis, one of the outstanding problems encountered is the lack of field samples, the uneven distribution of gold content in the sample and the determination of the amount of very scar contradiction. Therefore, how to make the collection of geochemical samples of gold, the preparation of samples and the amount of analysis samples basically meeting the measurement requirements reasonable integration are the problems to be solved in the current geochemical exploration work of gold. More than a decade ago, when the geochemical prospecting of gold was vigorously carried out in foreign countries, the above problems have also been encountered. Some geochemical exploration workers investigated and tested this and reported that it is generally believed that gold geochemical exploration samples are collected Weight, sample preparation, and the size and weight of laboratory samples sent are reasonable estimates of gold
