Abstract

In this study, rare earth elementsRare earth elements in bastnasite oreOre from Eskişehir, Turkey, were extracted by leachingLeaching using EG-FeCl₃-based deep eutectic solventDeep Eutectic Solvents (DES) together with the following solvent extractionExtraction. LeachingLeaching conditions such as temperature, FeCl₃ molarity, solid–liquid ratio (S/L), time, and mixing speed were determined using Taguchi orthogonal (L32) method. About 62.704 wt.% of light REEs (La, Ce, Nd, Pr) were dissolved after the calcination of the oreOre 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 extractionExtraction. D2EHPA extracted Y and Th from the leachate sufficiently. The highest distribution ratio for both elements was 17.28 and 8.39, respectively. Following to extractionExtraction, 74% of Y has been stripped back to 2 M HNO₃ solution.
