Abstract: |
Tin anode slime is the semifinished product in the process of tin metallurgy. It contains a mass of precious metal – gold and silver. It is realistic to exactly measure the content of gold and silver in tin anode slime. Fire assay could realize the jointly measurement of gold and silver by eliminating the interference of bismuth and Precious metals . This method is high accurate and good precision. The percentage recovery is between 97.47% and 101.66%. It could realize the high grade test of gold and silver in tin anode silme. |
