The mixer settler is widely employed in the extraction and recycling of battery materials. The improvement of the separation efficiency is one of the most important issues. In order to investigate the effect of agitating speed on the flow characteristics and settling performance, both computational fluid dynamics coupled population balance model simulations and experiments with particle image velocimetry...
Mixer-settlers have been widely employed in the rare earth element separation industry. Presently, reducing the loss of reagents and occupied areas and achieving a highly efficient separation in the settler are challenging issues. In this work, we report numerical simulations of the liquid–liquid flow in a stirring settler and thereafter describe the experimental validation. A computational fluid...
