摘要
对于含金量大于 10 0g/t(Fe<5 % )的选金产品采用王水溶解后 ,无需富集及与大量杂质分离 ,直接用原子吸收光谱法测定 ,可以得到满意的结果 ,其相对标准偏差 <6 %。作为选金产品中金的测定方法 ,具有成本低、速度快、工效高、劳动强度小的特点 。
The directly measuring method of gold by AAS is introduced for gold >100g/t and Fe<5% in mineral processing product. The sample is dissolved in aqua regia without enrichment and separation from impurities and successful result is obtained, the relative standard deviation is <6%. The low cost, high efficiency, and quick determination are the advantages of this method. It is applicable to online analysis of production.
