In this study; the elements in the Nd-Fe-B hard magnetic structure have been recovered by hydrometallurgical processes. The rare-earth elements in the scrap (Nd, Dy and Pr) Nd-Fe-B hard magnet have been extracted by using hydrometallurgical process and then they have been recovered to compound form. Nowadays, the most used magnets are Nd-Fe-B hard magnets in electronical devices. This study also containing recovery or evaluate the other elements (Fe, B, coating materials) that in the magnet system. The chemicals that have been used during the study will be available again and avoid the poisonous gas emission. If the gas emission is cannot be avoided, these gases will be reused, stored or harmonized. The process will be designed for pilot scale industrialization. Nd-Fe-B hard magnets will be dissolve in solvent and the solution will be characterized. Precipitation agent and parameters will be determined and precipitation/extraction processes are proceed. The process efficiency will be calculated after the final characterization. The optimum experiment parameters will be determined.
