含碳金精矿中金的碘量法实验分析

Experimental Analysis of Gold in Carbonaceous Gold Concentrate by Iodometry

金在试样当中通常显示出单质状态,并且分布不均,故而,若想确保分析结果准确性,首先试样细度应不大于0.074mm,均匀性应满足要求。针对金精矿当中含硫、砷、碳进行实验分析,对样品进行分段焙烧来消除干扰,使准确度、精密度明显提升,从而满足检测要求。

Gold usually shows a simple state in the sample and is unevenly distributed.Therefore,in order to ensure the accuracy of the analysis results,the sample fineness shall not be greater than 0.074mm and the uniformity shall meet the requirements.Based on the experimental analysis of sulfur,arsenic and carbon in gold concentrate,the samples were roasted in sections to eliminate interference,and the accuracy and precision were significantly improved,so as to meet the detection requirements.
