| Abstract: |
| Nd 2O 3 is produced from waste Nd-Fe-B material by using sulfuric acide-multisalt method. The test results show that the purity of Nd 2O 3 recovered is more than 95% and the recovery is more than 85%, other process and economic data are also better. This technology is feasible and stable. The application of this process technology in industrial production is also feasible. |
