摘　　要：锡阳极泥是锡冶炼过程中的一种中间产物,其中含有大量的金、银等贵金属。准确测定锡阳极泥中金、银含量有很重要的现实意义。采用火试金法能实现锡阳极泥中金、银含量的连续测定,方法准确度高,精密度好,金、银回收率在97.46%~101.66%,能很好地满足锡阳极泥中高品位金、银的测定。Tin anode slime is one of the intermediates in the process of tin metallurgy. It contains a mass of precious metal--gold and silver. It is of great importance to determine the content of gold and silver in tin anode slime. Fire assay method can meet needs of continuous determination of gold and silver by eliminating the interference of bismuth and precious metals. This method is of high accuracy and good precision. The recovery is 97.46~101.66%. It can be used for the measurement of high grade gold and silver in tin anode silme.
