Recommended separation processes for ion-absorbed rare earth minerals

Synthesis of hybrid bionanocomposites and their application for the removal of rare-earth elements from synthetic wastewater

“…Figure 3: Schematic illustration of precipitation, solvent extraction, ion-exchange and adsorption process for REEs recovery from solid and liquid waste stream Naphthenic acid was utilised for Y extraction from Ln [60], however, reagent losses and change in composition were reported due to solubility in water [61]. To overcome this, CA 12 [62] and CA 100 [63] were examined and it was concluded that, compared to Versatic 10, CA 100 extract REEs at lower pH [63].…”
