Nd_2O_3 Recovery from Sintered NdFeB Scrap AITranslate
Abstract AITranslate
The process flowsheet of Nd2O3 recovery from the scrap of sintered NdFeB magnet is studied. Based on the chemical properties of the elements in the scrap, Na2SO4 double-salt precipitation and oxalate secondary precipitation were employed in Nd2O3 recovery respectively. Both the impurity content and recovery rate are compared between the different recovery methods to obtain simple and feasible process conditions of high benefit. The test results show that rare earth elements are precipitated more completely by Na2SO4 double-salt precipitation, the product also has a higher purity and the Nd2O3 recovery is more than 82%.
