| titleOfInvention | A kind of method of sharpening segmentation recovering rare earth element from polishing powder from rare earth waste residue |
| abstract | The present invention discloses a kind of method of sharpening segmentation recovering rare earth element from polishing powder from rare earth waste residue, the technical scheme utilizing sectional type to extract realizes component sorting for the inefficacy polishing powder particle in polishing powder waste residue, from inefficacy polishing powder particle, extract La, Pr element one section of link, from inefficacy polishing powder particle, extract Ce element two sections of links; Based on two stage process flow process, rare earth element sharpening Separation and Recovery can be realized simultaneously; And by the impurity component of chemical process in different process sections removes wherein waste residue respectively and impurity element, thus guarantee the high physical index of product.The invention provides a kind of method that resource efficiency is high, processing condition are gentle, technical process is easy, product meets high physical index. |
