| 中文摘要: |
| 某高碱性含银氧化铜矿氨浸渣含银145.55 g/t。对氨浸渣进行了浮选回收银的试验，结果表明，采用三粗一扫两精的流程，经过闭路流程试验，可获得达到计价标准的银精矿，其银品位为1999.58 g/t、回收率80.78%。 |
| 英文摘要: |
| The content of silver in high alkaline oxide copper leaching residue was 145.55 g/t. The flotation tests for recovering silver from ammonia leaching residue have been carried out. The results show that, adopting a flowsheet of three roughing-one scavenging-two cleaning, a silver concentrate with Ag content of 1999.58 g/t was obtained through the closed circuit process experiments and the recovery of silver was 80.78%, which achieved the valuation standard of silver concentrate. |
