  separation enrichment
For practical samples, pre- and post-separation enrichment techniques probably are required.
      


The optimum condition of the separation enrichment by column chromatography with activated charcoal and sodium sulfite strip and extraction of trace gold with TMK-isoamyl alcohol has been studied. A preparation method of standard colors series is described using cobalt chloride, potassium chromate and copper sulfate. This method is simple and convenient, rapid and low cost. 1×10~(-3) ppm gold in the rock sample can be determined by this method.

本文叙述了用活性炭色层柱分离、亚硫酸钠解吸、TMK-异戊醇萃取比色测定痕量金的方法。采用了以硫酸钴、铬酸钾和硫酸铜等无机盐配制模拟标准系列,可以长期使用。本法操作简单,快速,成本低,工效高。一人一天可以分析30个以上试样,能测定出1×10~(-3)ppm的金含量,适用于地质普查金矿中大批试样的分析。

The sampling weights of gold sample and the gold content by weight in ores, particle size of sample, mineral composition, modes of occurrence of gold, gold particle size in ore, concentration of gold in minerals, separation-enrichment and analytical method, allowable error and economic benefit are discussed. And a suggestion for sampling weight in geochemical sample analysis is made.
