Modeling Preparative Chromatographic Separation of Heavy Rare Earth Elements and Optimization of Thulium Purification
Rare Earth Elements are in growing demand globally. This paper presents a case study of applied mathematical modeling and multi objective optimization to optimize the separation of heavy Rare Earth Elements, Terbium-Lutetium, by means of preparative solid phase extraction chromatography, which means that an extraction ligand, HDEHP, is immobilized on a C18 silica phase, and nitric acid is used ...
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 کاملRecovery and Separation of Rare Earth Elements Using Salmon Milt
Recycling rare earth elements (REEs) used in advanced materials such as Nd magnets is important for the efficient use of REE resources when the supply of several REEs is limited. In this work, the feasibility of using salmon milt for REE recovery and separation was examined, along with the identification of the binding site of REEs in salmon milt. Results showed that (i) salmon milt has a suffi...
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 ...
متن کاملConcentration and recycling of rare earth elements (REEs) from iron mine waste using a combination of physical separation methods
This study aims to investigate and optimize the effects of the main parameters including the particle size, gravity and magnetic separation combination, high gradient magnetic separation, magnetic field intensity, shaking table slope, washing water flow, and electrostatic separation upon the rare earth element (REE) recoveries from iron mine waste. The electron microprobe showed that high amoun...
