1 Scope

This section specifies the method for the determination of gold and silver in lead electrolytic anode mud. This part is applicable to the determination of gold and silver in lead electrolytic anode mud. Determination of the range of gold 0.050kg/t ~ 1.000kg/t; Silver 50.00kg/t ~ 250.00kg/t.

2 method summary

The sample with the right amount of flux melting at the same time, lead to capture gold, silver to form a buckle. Other impurities and flux generated fusible slag, the use of The density of the lead and the slag is different from that of the slag and the slag is separated from the slag, and the gold and silver are obtained by soaking. The amount of gold and silver is measured by weighing method. Use gold insoluble In the nature of nitric acid, gold and silver separation, with the weighing method to determine the amount of gold, the amount of gold minus the amount of silver.

3 reagent

Unless otherwise stated, only the reagents identified as analytical reagents and distilled or deionized water or comparable purity were used in the analysis. 3.1 anhydrous sodium carbonate, powder, industrial pure. 3.2 lead oxide, powder. (Au < 0.01 g/t, Ag < 0.2 g/t) 3.3 Silica, powder, industrial pure. 3.4 borax, powder, industrial pure. 3.5 sodium chloride, powder, industrial pure. 3.6 Starch, powdery. 3.7 nitric acid (1 1), without chloride ions. 3.8 nitric acid (1 7), without chloride ions. 3.9 glacial acetic acid (1 3).
