The report of Test on the Recovery of Bismuth Metal from Lead Bullion |
| Abstract |
The concentration of Bi-wet dross is a questionable problem in order to recover Bismuth metal from Bi-dross produced in the debismuthizing process. We could concentrated this Bi-dross up to 50% of Bismuth by cupellation, then oxidized the lead selectively. This is a reverse utilization of the principle that Bismuth metal in lead is not eliminated by oxidation. So we could produced high grade and salable Bismuth metal by using the Chlorination method which not only eliminated the traces of lead, but zinc and other impurities as well in addition to cupellation. |
