Test of Using Quality Method of Chloridizing Separated Silver to Analyse Rough Gold

Using aqua regia to dissolve rough gold, contaning impurities such as silver and lead are separated and then the gold can be reduced by reducing agent. Comparing with old method of separated silver by nitric acid, the test shows that the quality method which uses chloridizing separated silver to analyse rough gold is simple and of high precision and can meet the requirement of gold production.
