| dc.description.abstract | Modern technologies depend on rare earth elements (REEs), but extracting these individuals is still difficult, particularly in countries with limited resources like Malaysia. Even though rare earth elements (REEs) are important, it was not constantly easy to optimally utilize their extraction, especially through solvent extraction. By characterizing RE-Oxalate and investigating the effects of various extractant types and concentrations on REE separation, this study addresses this knowledge gap. The characterization of RE-Oxalate was performed using X-ray Fluorescence (XRF), X-ray Diffraction (XRD), Fourier Transmission Infrared (FTIR), and Inductively Coupled Plasma Optical Emission Spectrometry (ICP-OES). These methods provided detailed information on the composition and mineral phase of the raw material. This study aimed to characterize RE-Oxalate and investigate the effect of extractant types on REE separation. Two types of extractants (Cyanex 272 and Cyanex 572) with different concentrations (10%, 20%, and 30%) were manipulated by factorial design at fixed pH via this study to compare their efficiency towards the solvent extraction performance. The major phase found in the raw material is the crystalline phase. The results show that 20% Cyanex 572 can recover a higher percentage of REEs than Cyanex 272 at pH 1. This suggests that Cyanex 572 holds promise for optimizing REE separation processes. Cyanex 572 also has the potential for efficient REE extraction, providing a viable path forward for the mineral industries to enhance REE recovery | |
