| Abstract: | Platinum group elements and gold in sample were enriched by lead fire assaying, after adding 1 mg silver and melting at 950 ℃, lead button containing precious metals was obtained. Then lead button was separated from slag, silver grains containing platinum, palladium and gold were obtained by soot blowing at 900 ℃. Putting the alloy grain into the electrode, contents of platinum, palladium and gold were simultaneously determined by the emission spectrometry. |
