Abstract

THE INVENTION PROVIDES A METHOD FOR RECOVERING USEFUL MATERIALS FROM RARE EARTH-IRON-BORON BASED MAGNET SCRAP THAT ALLOWS EFFICIENT RECOVERY OF IRON AND BORON AS FERROBORON AND RARE EARTH ELEMENTS AS OXIDE, FROM RARE EARTH-IRON-BORON BASED MAGNET SCRAP. THE METHOD INCLUDES THE STEPS OF OXIDIZING RARE EARTH-IRON- BORON BASED MAGNET SCRAP IN AN OXYGEN-CONTAINING ATMOSPHERE, PREPARING A MIXTURE FOR THERMIT REACTION CONTAINING THE OXIDIZED MAGNET SCRAP AND ALUMINUM AND/OR AN ALUMINUM ALLOY, EFFECTING THERMIT REACTION OF THE MIXTURE FOR THERMIT REACTION FOR GENERATING FERROBORON AND SLAG, AND SEPARATING THE FERROBORON OBTAINED THROUGH THE THERMIT REACTION FROM THE SLAG.
