Rare earth elements (REEs), a group of 15 lanthanides, have garnered widespread interest due to their application in batteries, lightweight alloys and medical equipment, amongst several other applications. Despite growing demands, there are restricted sustainable engineering practices that could build steady supply these metals, with mineral metal mining being the major pathway for REE production. This predicament, turn, provides window opportunity REEs be mined from secondary sources such as coal fly ash, e-wastes & mine tailings. Mining sources, also called urban mining, offers alternative production pathways, reduces monopolization limited locations around world. Coal residual by-product combustion process, promises an important source different associated minerals parent coal. The utilization waste stream(s) legacy coal-fired power plants, embodies underlying principles utilization. Understanding ash properties through characterization techniques SEM-EDX, XRD, synchrotron-based µ-XRF µ-XANES sheds light onto various minerals, which REEs, often subsequently play crucial role developing leaching separation methodology. review focuses on latest most significant results published extraction it's hydrometallurgical pathways direct acid leaching, solvo-metallurgical utilizing deep eutectic solvents ionic liquids, subsequent recovery processes via solvent electrochemical separation, membrane technique.

Increasing generation of electronic waste (e-waste) is a major concern for emerging rare earth elements (REEs) pollution if not appropriately disposed of. Nevertheless, e-waste could be considered as secondary source critical REEs mining. Under the context circular economy, this review focuses on selective recovery from using ionic liquid (IL) extraction. ILs demonstrate sustainable alternative to organic volatiles used in traditional solvent extraction process. Despite insufficient literature applications limited categories real e-waste, comprehensively summarizes latest studies (mostly uncontaminated) IL and existing data indicate encouraging outcomes terms extractability selectivity. Roles have been critically analyzed. The has systematically illustrated fundamental design REEs, including bifunctional task-specific ILs, incorporation dilutant/extractant, non-fluorinated etc. This knowledge greatly facilitate cost-effective e-waste. must completely assessed extractability, selectivity, reusability. Synergistic based quaternary phosphonium salts are discussed realize excellent into phase leaving non-REEs aqueous easier separation. Overall, regeneration spent subsequent separation extracted also crucial novel ILs. industrialization technology would require more efficiency rate
