This work is aimed at optimizing a settler structure in a mixer-settler.Two different aspects have been considered.Firstly,the flowcharacteristics of a settler have been examined by computational fluid dynamics(CFD)si...
For the characteristics of good operability,high efficiency,simple structure,and easy amplification,the mixer-settler becomes one of the most widely used extraction equipment in the nuclear and the rare earth industry...
The instantaneous extractive behavior of U(Ⅵ)and nitric acid by 30%TBP/OK in mixersettler was studied in this report.The each-stage and instantaneous samples were obtained in different time from start-up filling to s...
