North America of American Rare Earths Limited. "The prospect of a sustainable, reusable, high-efficiency process that could extract, separate and purify scandium, yttrium and individual, high-value, rare-earth magnet metals could revolutionize the industry. The simplicity we see in the technology co...
In order to recover the rare earth elements (REEs) from neodymium permanent magnet scraps, Fe 2 O 3 , B 2 O 3 , and FeO–B 2 O 3 fluxes were designed to extract the REEs. The REEs containing oxides were successfully separated from the Fe-based metals at the temperatures of 1,673,...
Several phosphate esters in which calixarenes act as either uni- or bi-dentate ligands towards PV have been investigated as solvent-extraction agents for the rare-earth metals (La to Lu, excluding Pm, plus Y). Extraction of picrate salts into dichloromethane, ethyl acetate and tributyl phospha...
PURPOSE: To provide a method for separating and refining rare earth metals, in which the separation factor of every adjacent rare earth elements from each other is large and the rare earth metals can be back-extracted with a dilute mineral acid and no gelation occurs even when the amount to...
