Separation 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 کاملBioleaching of rare earth elements from monazite sand.
Three fungal strains were found to be capable of bioleaching rare earth elements from monazite, a rare earth phosphate mineral, utilizing the monazite as a phosphate source and releasing rare earth cations into solution. These organisms include one known phosphate solubilizing fungus, Aspergillus niger ATCC 1015, as well as two newly isolated fungi: an Aspergillus terreus strain ML3-1 and a Pae...
متن کاملSolvent 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 کاملUse of Phosphate Solubilizing Bacteria to Leach Rare Earth Elements from Monazite-Bearing Ore
In the present study, the feasibility to use phosphate solubilizing bacteria (PSB) to develop a biological leaching process of rare earth elements (REE) from monazite-bearing ore was determined. To predict the REE leaching capacity of bacteria, the phosphate solubilizing abilities of 10 species of PSB were determined by halo zone formation on Reyes minimal agar media supplemented with bromo cre...
متن کاملA novel hybrid neural network for modeling rare-earth extraction process
Although neural networks are universal approximators, they are black-box models and it is difficult to obtain a suitable neural structure for a special unknown nonlinear system. Since many physical systems can be modeled by mechanistic models, we use these information to modify the normal neural identifiers and propose a novel neural modeling approach in this paper. This model includes a linear...
