金矿石中高含量金元素测定方法的研究及比对分析
|
摘要
本文建立了对金矿石中高含量金元素的化学分析流程及不同分析流程的对比性研究,对高温焙烧处理后的样品采用1:1王水混合溶液溶解浸取,并对样品的浸取时间,振荡吸附时间、振荡吸附频率及解脱剂硫脲浓度条件进行了优化,采用多次吸附法和分液法对高含量金的测定进行对比性分析。实验方法采用1:1的王水混合溶液溶解浸取金、泡沫塑料富集、硫脲解脱、火焰原子吸收测定金的含量。
This paper established the chemical analysis of the genesis of high gold content of gold element flow, and comparative study of different analysis process, after high temperature roasting process of the sample the 1:1 aqua regia mix solution of leaching, and the leaching time of sample, the oscillation of adsorption time, oscillation frequency and release agent thiourea concentration conditions are optimized, using multiple adsorption method and liquid method for the determination of high content of gold for comparative analysis. Methods: gold was dissolved and leached in a 1:1 mixture of aqua regia, and the content of gold was determined by flame atomic absorption spectrometry
