| titleOfInvention | Neodymium iron boron waste recycling system and method |
| abstract | The invention relates to a neodymium iron boron waste recycling system and a recycling method, the neodymium iron boron waste recycling system comprises a neodymium iron boron waste supply unit, an acid leaching unit, a first solid-liquid separation unit, an acid leaching solution spray pyrolysis unit, a water leaching unit, a second solid-liquid separation unit, a water leaching solution extraction unit and a hydrochloric acid recycling unit, effective separation of iron and rare earth metal is realized through the arrangement of the acid leaching solution spray pyrolysis unit, the iron and the rare earth metal are respectively recycled, the process is environment-friendly, and huge economic benefits are generated through recycling of the rare earth elements. The recovery method is simple to operate, and the consumption of the hydrochloric acid and the discharge amount of the hydrochloric acid are reduced by recovering the hydrochloric acid. |
