Solvent Extraction of Rare Earth Metal by a Continuous Stirred Vessel
The solvent extraction of neodymium, a rare earth metal, was studied with a continuous stirred vessel. One of the widely used extractants, 2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester (PC-88A), diluted with kerosene was selected as an extracting organic solvent. First, the extraction equilibrium of neodymium between aqueous and organic phases was measured in a batch-wise experimental ru...
متن کاملSeparation and Recovery Process for Rare Earth Metals from Fluorescence Material Wastes Using Solvent Extraction
The separation and recovery of rare earth metals from fluorescence material waste was investigated by using solvent extraction with 2-ethylhexyl phosphonic acid mono-2-ethylhexyl ester in kerosene. Extraction equilibrium expressions were established for the trivalent metals (La, Ce, Eu, Tb, Y and Al) and divalent metals (Ca, Sr and Ba) for both single and multi components systems. The process s...
متن کاملSolvent Extraction and Transport of Rare Earth Metal Ions Using 5.11.17.23-Tetra-tert-butyl-25,27-bis (diethylcarbomoylmethoxy)-26,28-dihydroxy Calix[4]arene
The solvent extraction of rare earth metal ions from nitrate solutions by 5.11.17.23-tetra-tert-butyl-25,27-bis(diethylcarbamoylmethoxy)-26,28-dihydroxycalix[4]arene (L) in 1,2-dichloroethane has been investigated. The alalysis of the extraction equilibrium obtained from a mixture of La3+, Eu3+, Er3+ and Y3+ revealed that the extracted species hav...
متن کاملRare-earth metal hydroxylamide complexes.
The rare-earth metal hydroxylamide compound Y[N(SiHMe2)2]2[ONBn2][THF] (1) was prepared by the silylamide elimination pathway from the reaction of N,N-dibenzylhydroxylamine, Bn2NOH (Bn = CH2C6H5), with Y[N(SiHMe2)2]3[THF]2 and was characterised by multinuclear NMR spectroscopy and elemental analysis. The compounds [Cp2Y(ONBn2)]2 (2a) [Cp2Sm(ONBn2)]2 (2b) were obtained by the reactions of MCp3 (...
متن کاملOn the Extraction of Rare Earth Elements from Geothermal Brines
The availability of rare earth elements from primary resources has come into question in the last two decades. This has sparked various government and industry initiatives to examine potential rare earth element resources apart from virgin ore bodies. Geothermal fluids are potentially significant sources of valuable minerals and metals, while co-recovery with geothermal energy production would ...
