摘　　要：高铋渣是有色金属冶炼过程中的一种中间产物,其中含有大量的金银贵金属。准确测定其中金银含量有很重要的现实意义。采用火试金法能实现高铋渣中金、银连续测定,该方法准确度高,精密度好,金银回收率为97%～99%,能很好地满足铋渣中高品位金银的测定。Bismuth slag is intermediate product in metallurgy process, which contains a mass of gold and sil- ver. It is of great realisitc significance to exactly measure the content of gold and silver in bismuth slag. Fire assay could realize the continuous determination of gold and silver in the slag with high accuracy and good precision. The recovery of gold and silver is between 97% and 99% and meets the requirement of determination of high grade gold and silver in bismuth slag.
