Abstract Scope |
Scraps are become a good source for demand metals recovery, as per the DoE, USA some of the rare earths such as neodymium, praseodymium, dysprosium and terbium are recognized as critical situation for future demands. In the 21st century the hi-tech industrialization is very fast growing all over the globe at the same time the human generated waste also being a big burden for environment.
In this experimental study is concern with processing of the permanent magnets scraps for rare earths extraction with possible separation from each other. The leach liquor contains following rare earths: praseodymium, dysprosium, neodymium and terbium. In a leaching stage oxidation and roasting process applied to prevent the iron interference as much as possible. The leach liquor was processed with liquid-liquid extraction processing. The proper extractant with proper experimental conditions were optimized for above said rare earths separation was optimized. |
