无需添加盐析剂的NASX工艺从模拟NdFeB磁浸液中回收Nd(III)和Dy(III)

Based on the optimization of parameter extraction discussed earlier, a NASX process without adding a salt-out agent is proposed for the recovery of Nd(III) and Dy(III) from simulated NdFeB magnetic immersion solutions. The actual Nd(III)/Dy(III) ion concentration and Nd(III)/Dy(III) ratio in the HNO3-dissolved NdFeB magnetic solution reported in previous studies were used as references.
