| Abstract Scope |
In this study; rare earth elements in bastnasite ore from Eskişehir, Turkey was extracted by leaching using EG-FeCl3 based deep eutectic solvent together with the following solvent extraction. Leaching conditions such as temperature, FeCl3 molarity, solid liquid ratio (S/L), time, and mixing speed were determined using Taguchi orthogonal (L32) method. 62.704 wt.% of light REEs (La, Ce, Nd, Pr) were dissolved after the calcination of the ore using 1 M of FeCl3 at S/L ratio of 0.05, with 600 rpm of stirring rate for 16 h at 50°C. Heavy REEs and Light REEs were separated by solvent extraction. D2EHPA extracted Y, and Th from the leachate sufficiently. Distribution ratio for both elements was 17.28 and 8.39, respectively. |
