| Abstract: | The fundamental process for preferential dissolution by hydrochloric acid is discussed.Neo- dymium and dysprosium are extraction removed by the process from NdFeB waste materials,w (Dy_2O_3) in produced Dy_2O_3 is over 99%,impurity content in produced Dy_2O_3 is accord with national standard.The recovery of rare earth metals is over 92%,and production is stable. |
