Neoteric Solvents for Rare Earths Processing: Perspectives on the Potential of Ionic Liquids and Deep Eutectic Solvents From a Bibliometric Analysis

Solvent Extraction and Ion Exchange, Journal Year: 2024, Volume and Issue: unknown, P. 1 - 35

Published: Dec. 17, 2024

Rare earth elements have become critical in today's technological societies and neoteric solvents, such as ionic liquids (ILs) deep eutectic solvents (DESs), are being called upon to replace traditional organic order improve the environmental sustainability of rare processing. A bibliometric analysis was performed investigate scientific documents published Scopus database until 2023 regarding use ILs DESs for earths The search identified 731 papers since pioneering works last years 20th century amount accumulated throughout time followed a quadratic evolution. China, main producer worldwide, most prolific country, publishing 276 (37.8% contribution), almost four times higher than contribution United States (75 documents), second country ranking. triad important keywords consists liquids, extraction. In addition separation by solvent extraction, leaching from mineral ores secondary resources e-waste using has been extensively investigated. addition, these innovative can be considered promising media electrowinning processes obtain pure earths.

Deep Eutectic Solvent (TOPO/D2EHPA/Menthol) for Extracting Metals from Synthetic Hydrochloric Acid Leachates of NMC-LTO Batteries

Metals, Journal Year: 2024, Volume and Issue: 14(12), P. 1441 - 1441

Published: Dec. 16, 2024

The recycling of lithium-ion batteries is increasingly important for both resource recovery and environmental protection. However, the complex composition cathode anode materials in these makes efficient separation metal mixtures challenging. Hydrometallurgical methods, particularly liquid extraction, provide an effective means separating ions, though they require periodic updates to their extraction systems. This study introduces a hydrophobic deep eutectic solvent composed trioctylphosphine oxide, di(2-ethylhexyl)phosphoric acid, menthol, which Ti(IV), Co(II), Mn(II), Ni(II), Li+ ions from hydrochloric acid leachates NMC (LiNixMnyCo1−x−yO2) with LTO (Li4Ti5O12) anodes. By optimising molar oxide/di(2-ethylhexyl)phosphoric acid/menthol mixture 4:1:5 ratio, high efficiency was achieved. demonstrated stability over 10 cycles, conditions its regeneration were successfully established. At room temperature, DES exhibited density 0.89 g/mL viscosity 56 mPa·s, are suitable laboratory-scale processes. Experimental results laboratory setup mixer-settlers confirmed Ti(IV) Co(II) context kinetics.
