| Abstract: |
| A new process for comprehensive utilization of dust containing silver and selenium from silver-refining furnace was studied. The new technology adopted the acid-leaching and flotation process to accomplish the separation of silver and selenium from lead, bismuth, antimony and other impurities. The silver was recovered by its being enriched in silver concentrate, and selenium was enriched in the solution of acid-leaching and silver concentrate. The plant practice shows that the recovery of silver and selenium is above 95% and 85% respectively. |
