| Abstract: |
| With tantalum-bearing high temperature alloy scrap as raw material, tantalum was recovered by processes of acidic leaching, extraction, purification, stripping, and tantanlum precipitation. The results show that tantalum could be successfully recycled from tantalum-bearing alloy scrap with 99% above purity of recycled product and tantalum recovery of 90% above. |
