The device on the left is the XRF machine used to find the elements weight percent. Recommendation The objective of this SURF project was to design a method to extract rare earth elements from the monolith of a alytic converter. The monolith is coated with different metals to clean emissions. Rare earth metals like Cerium, Yttrium and Lanthanum are all part of the monolith, Cerium having ...
· Rare‐earth‐metal separations based on kinetic differences have not been examined. Herein, we demonstrate a new approach for rare‐earth‐element separations by exploiting differences in the oxidation rates within a series of rare earth compounds containing the redox‐active ligand {2‐(t BuN(O))C 6 H 4 CH 2} 3 N] 3−. Using this method, a single‐step separation factor up to 261 was ...
separation of rare earths in macroquantities ; however, both have been used effectively for the separation of tracer quantities of the rare earths and actinides. Freiling and Bunney (10) have reported optimum conditions for rareearth separations with ammonium lactate as the eluting agent.

rare earth metal ions and the anion of ~DTA have been measured at a temperature of °C and an ionic strength of by two inde pendent methods. The two methods are shown to supplement each other, one being more accurate for the lighter rare earths and the second method more accurate for the heavy rare earths. In the first method, the rare earthEDTA stability constants were calculated ...
· Rare earth metals — those 17 chemically similar elements at the bottom of the periodic table — are in almost every piece of technology we use from cell phones to wind turbines to electric cars. Because these elements are so similar to each other, the process of separating them is time consuming, expensive, and dangerous. Processing one ton of rare earths can produce 2,000 tons of toxic ...

· Rare earth elements (REEs) are critical and strategic materials in the defense, energy, electronics, and automotive industries. Currently, China produces about 85% of the world supply of rare earth metals and oxides. Approaches for recovering rareearth species from natural and waste sources is increasingly important to reduce our dependence on ...
· Rare Earth Elements (REE) or Rare Earth Metals are actually a set of 17 chemical elements in the scientific periodic table that are specifically the fifteen lanthanides plus scandium and yttrium. The scandium and yttrium are considered rare earth elements since they tend to occur in the same ore deposits as the lanthanides and exhibit similar chemical properties. They are used in a wide .

Three rare earth metals are studied Ce 3+, Eu 3+ and Y 3+ with an increasing concentration of CMPO (black symbols) in comparison to the same extraction but in dodecane. They prove that the extractability of CMPO is highly better in IL than in a classic organic solvent (the volume of .
· Breaking China's Rare Earth Monopoly. China's dominance in rare earths is the result of years of evolving industrial policies since the 1980s, ranging from tax rebates to export restrictions. In order to reduce dependence on China, the and Japan have made it a priority to diversify their sources of rare earth metals.
[en] A micro solvent extraction system for the separation of rare earth metals has been investigated. The micro flow channel was fabried on a PMMA plate. Extraction equilibrium was quickly achieved, without any mechanical mixing. The solvent extraction results obtained for the Pr/Sm binary solutions revealed that both rare earth metals are firstly extracted together.
This review has critically looked into a few authors' recent reviews on six major processes of rare earth processing steps and each step is considered as important to produce both high quality ...
The REMSIL (Rare Earth Metal Separation with Ionic Liquids) project focuses on the design and development of novel technologies based on task specific ionic liquids (TSILs), solidsupportedionic liquids (SSILs) and ionogel membranes for the separation and recovery of hightech rare earth metals (REMs).With the current demand for these hightech metals [.]
the separation/recovery of rare earth metals is illustrated in Fig. 1 [28]. The recovery of REEs could be processed using molten salt electrolysis through four steps. First, an anode containing rare earth metals is dissolved into the molten salt. Second, the target metal ions are selectively deposited on the diaphragm surface to form rare earth alloys. Third, the target rare earth metal ...

· "The estimated value of rare earth compounds and metals imported by the United States in 2018 was 160 million, an increase from 137 million in 2017," the USGS penned in its Mineral Commodities Summaries 2019 report. Roughly 80 percent of these rare earths were imported from China. Estonia (6 percent), France (3 percent) and Japan (3 percent) were other REE suppliers to the .
