Ion Exchange for the Purification of Co(II) or Ni(II) from Acidic and Ammonia Solutions in the Recycling of Spent Lithium-Ion Batteries
Thanh Tuan Tran, Man Seung Lee
Korean J. Met. Mater. 2022;60(12):902-911.   Published online 2022 Nov 25
DOI: https://doi.org/10.3365/KJMM.2022.60.12.902

Abstract
The recycling of critical metals like cobalt and nickel from spent lithium-ion batteries (LIBs) is of immense importance in sustainable manufacturing. This work aims to purify Co(II) and Ni(II) present in acidic and ammonia solutions using ion exchange. AG-1-X8 resin modified with thiocyanate anions (R4N+SCN resin) was used to separate..... More

Recovery of High-Purity Lithium Compounds from the Dust of the Smelting Reduction Process for Spent Lithium-Ion Batteries
Thanh Tuan Tran, Seong Ho Son, Man Seung Lee
손성호, 이만승
Korean J. Met. Mater. 2022;60(4):291-300.   Published online 2022 Mar 28
DOI: https://doi.org/10.3365/KJMM.2022.60.4.291

Abstract
The recovery of valuable metals such as cobalt, nickel, and lithium from spent lithium-ion batteries (LIBs) has attracted much attention. In this study, a hydrometallurgical process for the recovery of high-purity lithium compounds like Li2CO3 and Li3PO4 from dust containing Li, Co, Ni, Cu, Fe, Mn, and Si produced during..... More

Interactions Between Ionic Liquid (ALiCY) and TBP and their Use in Hydrometallurgy for Extracting Co(II) and Ni(II)
Thanh Tuan Tran, Man Seung Lee
Korean J. Met. Mater. 2020;58(6):423-432.   Published online 2020 May 14
DOI: https://doi.org/10.3365/KJMM.2020.58.6.423

Abstract
Ionic liquids have emerged in hydrometallurgy as potential extractants for metals. In this work, the interactions of ALiCY (R4N+A-) synthesized by Aliquat336 and Cyanex272, and a mixture of ALiCY and TBP, were analyzed using extraction data and FT-IR spectroscopy. Co(II) and Ni(II) were extracted from two HCl concentrations (1.0×10-4 and..... More

Comparison of the Extraction and Stripping Behavior of Iron (III) from Weak Acidic Solution Between Ionic Liquids and Commercial Extractants
Thanh Tuan Tran, Mudassir Iqbal, Man Seung Lee
Korean J. Met. Mater. 2019;57(12):787-794.   Published online 2019 Nov 22
DOI: https://doi.org/10.3365/KJMM.2019.57.12.787

Abstract
Fe(III) can be easily extracted from weak acidic solutions by organophosphorus extractants, but stripping a large amount of Fe(III) from the loaded extractants is very difficult. The extraction and stripping of Fe(III) from 2 pH chloride and sulfate solutions was performed with ionic liquids(ILs) and organophosphorus acidic extractants, and the..... More
