Mar 14, 2017 Ustynyuk, Y. A. et al. N,N'-dialkyl-N,N'-diaryl-1,10-phenanthroline-2,9-dicarboxamides as donor ligands for separation of rare earth elements with a high and unusual selectivity. DFT computational
The rare earths, or rare earth elements (REE), are a relatively abundant group of elements consisting of scandium, yttrium, and the 15 elements of the lanthanide series of the periodic table. Scandium (Sc) is the lightest rare earth element. Scandium is present in crustal rocks in amounts greater than lead and precious metals, but it rarely
Dec 18, 2021 Separation of hard actinides from rare earth metal ions is one of the challenging task as both these types of ions are hard ions. Therefore, from the view point of Hard-Soft Acid-Base principle, selecting suitable ligands is beyond the conventional procedure for their successful separation
Aug 04, 2019 The rare earth magnetic separator range achieves the most effective dry separation of paramagnetic minerals at high throughput rates. The range includes Rare Earth Roll (RERS) and Rare Earth Drum (REDS) Separators which are available in a range of configurations and sizes from lab units to full production units
Acid-free Dissolution and Separation of Rare-earth Metals Patent issued May 2020 #10,648,063 This invention is a simple, in-expensive and environmentally friendly chemical dissolution method for recycling NdFeB magnets
A method improves the extraction and separation of rare earth elements — a group of 17 chemical elements critical for technologies such as smart phones and electric car batteries — from unconventional sources. The method could eventually be scaled up to help develop a domestic supply of rare earth metals from industrial waste and
The article presents data on the solvent extraction separation of rare-earth elements (REEs), such as La(III), Ce(III), Pr(III), and Nd(III), using synergic mixtures of methyltrioctylammonium nitrate (TOMANO3) with tri-n-butyl phosphate (TBP) from weakly acidic nitrate solutions. Specifically, experimental results on separation of REEs, for the pair Ce(III)/Pr(III) for
