Electrostatic solvent extraction (ESX) is similar to conventional solvent extraction (SX) except that it uses electrostatic agitation, which promises to circumvent the inherent limitations of SX by allowing the production of very small droplets that can be made to maintain intense motion with minimal power consumption. An industrial application of the technique however is yet to be achieved.
Our work to develop its application in process metallurgy has now established that electrostatic field has no effect on the stability of the reagents or the chemistry of the process. We have also established that electrostatic fields allow the production of much narrower droplet size distributions than those of mechanically agitated contactors while maintaining high droplet motions and hence, high mass transfer rates. A contactor design that allows a volumetric flowrate that is comparable to that of a conventional SX column has also been achieved. These will be discussed in this presentation.
