摘要
建立了铜精矿中金的原子吸收和ＩＣＰ－ＡＥＳ分析方法。试样经高温焙烧后，用硫酸分解，使金与可溶性铜、铁等大量基体分离，残留物中金经王水溶解，用原子吸收光谱法或ＩＣＰ－ＡＥＳ测定。研究了最佳分析条件，并与经典火试金方法进行了比较，结果一致。ＲＳＤ为０．６～３．３％。
new method for the determination of microamount of gold in copper concentrates by AAS or ICPAES was developed .The sample was dissolved by sulfuric acid to separate Au from soluble Cu,Fe and any other soluble element .Then gold was determined in remains by using AAS or ICPAES .The best conditions of analysis were studied,and the result of this method conformed with that by fireassay method for the determination of gold.The accuracy of analysis and relative standard deviation are satisfactory.
