地质样品中金富集分离方法研究

Research of Gold Enrichment and Separation Method of Geological Sample

自然地质中金的含量较低且分布极不均匀,这就给金的测定增加了难度。运用金富集分离方法,可以降低干扰因素的影响,有助于提高地质样品中金含量测定的精确性。在开展金富集分离前,需要对地质样品进行预加工和分解处理,运用火试金法、吸附法、溶剂萃取分离法等方法,达到金富集分离的目的。再运用滴定法、光度法、发射光谱法等方法进行金的测定。地质样品中金的测定方法具有不同的优缺点,应综合比较考虑,完成地质样品中金含量的精确测定。

The low content and extreme uneven distribution of gold in natural geology increase the difficulty of gold measurement.Gold enrichment and separation method can reduce the influence of interference factor,and help to improve accuracy of gold content determination of geological sample.Before the gold enrichment and separation,it is necessary to preprocess and decompose geological sample,and use fire assaying,adsorption method and solvent extraction separation method,etc.to achieve the goal of gold enrichment and separation.There are different advantages and disadvantages of gold assaying method in geological sample.It is necessary to comprehensively compare,and complete the accuracy measurement of gold content determination of geological sample.
