Abstract

In this study, the leaching kinetics of rare-earth elements were investigated using HCl and HNO3 solutions. A standard crushed complex ore was utilized as raw material. The complex ore (particle size of under 54 µm) contains REE (Ce, La, Nd, Pr, etc.). Different leaching durations were selected for the kinetic studies. The highest leaching efficiency was obtained in HCl solution, and the leaching mechanism was identified to diffusion through a product layer. The rate constants of Ce, La, Nd, and Pr were calculated as 1.08 × 10−2, 0.86 × 10−2, 1.87 × 10−2, and 1.34 × 10−2 h−1, respectively.
