Bu çalışmada, Eskişehir-Kızılcaören yöresindeki üç farklı bölgeden alınan temsili numuneler harmanlanarak kompozit bir numune hazırlanmış ve liç deneylerinde bu numune kullanılmıştır. Tane boyutu analizi sonuçlarına göre, numunenin d50 ve d80 boyutları sırasıyla 0,45 mm ve 1,58 mm olarak bulunmuştur. Fraksiyonel tane boyutu analizi sonuçlarına göre numunenin %2,79 La, %2,27 Ce, %0,29 Nd, 450 ppm Y, %0,69 Th ve 200,3 ppm U içerdiği tespit edilmiştir. Liç deneylerinde -38 μm tane boyutunda numuneler kullanılmıştır. Liç deneylerinde, %15-50 katı oranı, 30-320 dakika liç süresi, 25-500 kg/ton NaOH dozajı ve 25-70oC liç sıcaklığı parametrelerinin Th ve NTE çözünme verimleri üzerine etkileri araştırılmıştır. Deneylerde optimum koşullar, % 35 katı oranı, 500 kg/ton NaOH dozajı, 120 dakika liç süresi ve 50oC pülp sıcaklığı olarak elde edilmiştir. Bu optimum koşullar altında yapılan deneyler sonucunda %65,15 Th, % 54,21 Cd, % 45,44 Nd ve %54,01 La çözünme verimleri elde edilmiştir.

In this study, a composite sample was prepared from the representative samples of the experiments taken from three different areas in Eskisehir-Kizilcaoren region, Turkey, and this composite sample was used for the leaching experiments. Considering the particle size analysis of the sample, the d50 and the d80 sizes of the sample were found to be 0.45 mm and 1.58 mm, respectively. It was determined from the fractional particle size analysis that the sample contained 2.79% La, 2.27% Ce, 0.29% Nd, 450 ppm Y, 0.69% Th, and 200.3 ppm U. The samples reduced to-38 μm were used for the leaching experiments. The leaching parameters, namely, 15-50% solids ratio, 30-320 min. of the leaching time, 25-500 kg/ton NaOH dosage, and 25-70oC pulp temperature were investigated in the leaching experiments. The optimum conditions for the leaching experiments for Th and REE (Ce, Nd, La) were obtained as 35% solids ratio, 500 kg/ton NaOH dosage, 120 min leaching time, and 50oC pulp temperature. As a result of the experiments carried out under these optimum conditions, 65.15% Th, 54.21% Cd, 45.44% Nd, and 54.01% La dissolution efficiencies were obtained.
