Abstract

In this paper, a method for determination of silver content in zinc anode mud by concentration of fire test gold is studied.Rich in silver by lead, form a lead buckle, to remove lead at suitable temperatures, when ash blows, lead oxidizes to lead oxide and penetrates a porous ash dish to remove lead and impurities, Silver is not oxidized and remains in the ash dish to form silver particles.Silver grain quality obtained by weighing method, Silver grain mass minus lead oxide blank silver mass is the amount of silver.The method does not require a second trial and has high efficiency, low cost, accurate results and good reproducibility, ability to direct production quickly and accurately, Suitable for modern enterprise production, This method can be used for the determination of the silver content in zinc anode mud 50 ~ 1000 g/t.
