Abstract
The
increasing importance of rare earth elements (REEs) in advanced technologies
has prompted extensive research on their extraction, notably neodymium (Nd) and
dysprosium (Dy), critical components for neo-magnet production. Researchers are
actively exploring Nd and Dy recovery from both primary and secondary REE
sources, often employing solvent extraction post-acid leaching for effective
separation. In this context, a study focused on extracting Nd and Dy from local
xenotime minerals utilizing acetic acid (CH3COOH) as the leaching
solution and Di-(2-ethylhexyl) phosphoric acid (D2EHPA) in kerosene at a 30%
concentration as the organic solvent. Energy Dispersive X-Ray Fluorescence
(ED-XRF) analysis gauged Nd and Dy concentrations pre and post-extraction. The
study identified optimal conditions, showing peak extraction efficiency: 99.4%
for Nd and 99.3% for Dy, achieved using a 1M leaching solution concentration
and a 1:1 aqueous-to-organic (A/O) phase volume ratio. The extraction process
demonstrated highest efficacy at 30 °C within a 20-min timeframe. Consequently,
the investigation highlights the potential of acetic acid as a xenotime
leaching medium for Nd and Dy extraction with D2EHPA. Therefore, this study proves
that CH3COOH is potentially be used as the leaching media of
xenotime for the extraction of Nd and Dy with D2EHPA.

Abstrak
Kepentingan yang semakin meningkat terhadap unsur bumi jarang (REEs) dalam teknologi canggih telah merangsang penyelidikan yang meluas terhadap pengambilan mereka, terutamanya neodimium (Nd) dan disprosium (Dy), komponen penting untuk pengeluaran neo-magnet. Penyelidik sedang mengkaji pemulihan Nd dan Dy daripada sumber REE utama dan sekunder, sering kali menggunakan pengekstrakan pelarut selepas pelarutan asid untuk pemisahan yang berkesan. Dalam konteks ini, satu kajian memberi tumpuan kepada pengeluaran Nd dan Dy daripada mineral xenotim tempatan dengan menggunakan asid asetik (CH3COOH) sebagai larutan pelarutan dan Di-(2-etilheksil) asid fosforik (D2EHPA) dalam kerosin pada kepekatan 30% sebagai pelarut organik. Analisis Serakan Tenaga Pendarfluor Sinar-X (ED-XRF) telah mengukur kepekatan Nd dan Dy sebelum dan selepas pengekstrakan. Kajian ini mengenal pasti keadaan optimum, mendedahkan kecekapan pengekstrakan puncak: 99.4% bagi Nd dan 99.3% bagi Dy, dicapai dengan menggunakan kepekatan larutan pelarutan 1M dan nisbah isi padu fasa akuos-ke-organik (A/O) 1:1. Proses pengekstrakan menunjukkan keberkesanan tertinggi pada suhu 30 °C dalam tempoh 20 minit. Akibatnya, penyelidikan ini menyoroti potensi CH3COOH sebagai medium pelarutan xenotim untuk pengekstrakan Nd dan Dy dengan D2EHPA. Oleh itu, kajian ini membuktikan bahawa CH3COOH berpotensi digunakan sebagai medium pelarutan xenotim untuk pengekstrakan Nd dan Dy dengan D2EHPA.
