Abstract

향류의 혼합-정치조를 사용한 희토류 금속의 회수과정에서 불순물로 함유된 Ru의 분리에 영향을 미치는 인자들을 규명하기 위하여 Ru의 화학적 특성과 장치계의 유동현상을 기초로 한 이론적 모델을 설정하였다. 정상상태의 농도분포에 관하여 제시된 모델의 결과는 실험결과와 거의 일치하였으며 컴퓨터에 의한 모델의 simulation으로 분리효율에 미치는 계의 특성을 검토, 해석하였다.
A theoretical model is developed on the basis of chemical properties of ruthenium and the hydraulic behavior of a countercurrent mixer-settler system to elucidate the separation factors of ruthenium contained as an impurity in the recovery process of rare earth metals. Predictions from the model were in good agreement with the experimental results for steady state concentration profiles. Application of the model is further extended to computer simulation in order to examine the system characteristics for improving separation efficiency.
