| Abstract: |
| Bismuth slag is the semifinished product in the process of metallurgy. It contains a mass of precious metal – gold and silver. It is realistic to exactly measure the content of gold and silver in Bismuth slag. Fire assay could realize the jointly measurement of gold and silver. This method is high accurate and good precision. The percentage recovery is between 97 and 99％. It could realize the high grade test of gold and silver in Bismuth slag. |
