Abstract

Effect of the change in aqueous-to-organic phase ratio on the performance of mixer?settler was summarized. The effect of aqueous-to-organic phase ratio on drop dispersion, mass transfer of target metal ion between phases in mixer chamber and phase separation in settler chamber were paid particular attention. In addition, the effect of impeller type and installation position on the performance of mixer?setter were discussed. How to meet the requirement from a wide aqueous-to-organic phase ratio in mixer?settler was suggested for complex separation. Future development of mixer?settler was indicated, including how to achieve high mixing efficiency in mixer chamber and high clarification efficiency in settler chamber under a wide aqueous-to-organic phase ratio range.
