| 摘 要： | 采用先低温焙烧除硫后再高温焙烧,通过王水溶样,对辉锑矿矿样焙烧方法的对比表明,利用方法焙烧样品,矿样不结块,金可溶解完全.方法经国家一级标准物质分析验证,结果与标准值相符.对实际样品测定的方法精密度为1.44%～4.79%(RSD,n=5).加标回收率在95.5%～104.3%,方法快速、准确,适用于高含量辉锑矿中金的批量样品分析.

| Abstract: | The contrast of the roasting methods of stibnite ore samples showed that the use of low-temperature calcination of the sample to remove sulfur,with high-temperature roasting of the sample,afterwards can dissolve gold completely by aqua regia,without the lump of the ore sample.The method has been applied to the determination of Au in the National Standard Reference materials and the results are in agreement with certified values with precision of 1.44%～4.79%(RSD,n=5).The recovery of the method was 95.5% ～ 104.3%.The method is rapid and accurate,and is applicable to the bulk sample analysis of gold in stibnite. |
