| Abstract: | This paper studies the method for reclamation and the separation of Nd,Dy and Co from NdFeB scrap.According to the chemical properties of the scrap component,we choose the methods of sulfuric acid dissolving, composite compound depositing of rare earth, base conversion, hydrochloric acid dissolving, composite compound depositing of iron and extract separation and so on,successfully extract the valuable components, and obtain the products of Nd_2O_3, Dy_2O_3 and Co_2O_3.This paper also studies the optimum dosage of each reagent to ensure the quality of products and reduce operating costs. |
