| Abstract: | By using sulfuric acid to react with the industrial waste from the production of Nd-Fe-B,then using phosphate to precipitate the Nd ion to seperate the Nd from Fe,through alkali transforming,acid dissolving and ammonia carbonate precipitating,the neodymium carbonate is obtained.After roasting it,the Nd 2O 3 with the purity of over 99.00% can be obtained,and the total recovery rate of Ne is more than 90.00%. |
