Recent Uses of Ionic Liquids in the Recovery and Utilization of Rare Earth Elements

Minerals, Год журнала: 2024, Номер 14(7), С. 734 - 734

Опубликована: Июль 22, 2024

The importance of rare earth elements as a basis for the development new technologies or improvement existing ones makes their recovery from raw and waste materials necessary. In this recovery, hydrometallurgy its derivative solvometallurgy play key roles due to operational characteristics, which are emphasized with use ionic liquids. This manuscript reviews most recent advances (2023 2024) in liquids unit operations (leaching separation technologies) aimed at these valuable strategic metals. Moreover, comprehensive review is presented chemicals advanced containing some elements.

Recent Advances in Indium Recovery

Metals, Год журнала: 2024, Номер 14(11), С. 1282 - 1282

Опубликована: Ноя. 12, 2024

Though indium has been removed from the fifth list (2023) of critical raw materials for European Union metals, its recovery is still paramount importance due to wide use in a series high-tech industries. As closely associated with zinc mining, recycling In-bearing wastes also interest, both profitable and environmental reasons. With unit operations (in hydrometallurgy pyrometallurgy or extractive metallurgy) playing key role indium, present work reviewed most recent innovations (2024) regarding these this valuable metal different solid liquid wastes.

Removal of furosemide from water by emulsion liquid membrane: Influence of experimental conditions and real water matrices

Journal of Engineering Research, Год журнала: 2024, Номер unknown

Опубликована: Март 1, 2024

This work investigates the removal of furosemide (FSM) from low pH aqueous phase by emulsion liquid membrane (ELM). The influence various experimental conditions on FSM permeation rate and subsequent stability, such as surfactant concentration, diluent type, stripping solution feed pH, solution/membrane volume ratio, emulsification time speed, stirring rate, initial emulsion/feed was evaluated. ability to extract in different natural complex matrices examined. ELM system is formed Span 80 (5% w/w) surfactant, hexane diluent, NaOH (0.01 N) agent, ratio 1/1, treatment 20/200, mixing 200 rpm. process demonstrates complete within a remarkably short span 20 min. In seawater mineral water, extraction efficiency 94.3% 96.8%, respectively, after Additionally, reported be excellent (100%), demonstrating remarkable remove recover water. For these reasons, technique particularly interesting for treating FSM-contaminated

Solvent Extraction of Gold(III) by 2-Ethylhexanol and Modeling of Facilitated Transport across a Supported Liquid Membrane

Processes, Год журнала: 2024, Номер 12(4), С. 771 - 771

Опубликована: Апрель 11, 2024

The solvent extraction of gold(III) by undiluted 2-ethylhexanol or dissolved in toluene from a HCl solution has been investigated this paper. numerical analysis gold distribution data suggests the formation HAuCl4·L and HAuCl4·2L (L = 2-ethylhexanol) species organic phase, with constants K11 38 K12 309, respectively. results derived have implemented solid-supported liquid membrane system. influence several variables on transport considered: feed receiving phases’ stirring speeds, concentrations carrier concentration phase as well presence base metals (Fe, Cu, Ni) platinum-group (PGMs) phase. Gold is influenced speed variation (feed phase) (membrane concentrations. Also, diffusional resistances to mass transfer are estimated, contribution each resistance estimated. recovered zero-valent nanoparticles.
