Reactor analysis for selective metal ion extraction in liquid dispersions. Progress report
The thrust of this research is to develop fundamental models for design of liquid-liquid extractors and for prediction of level of extraction and selectivity for separation of multiple metals in hydrometallurgical processing. Models employed will include the details of the thermodynamic chemical equilibria, chemical kinetics, mass transfer processes, and the effects of droplet mixing. The basic dispersed phase model which incorporates the above mentioned phenomena and the experimental techniques to verify the model was developed in the earlier work in this program. Two problems addressed in this program are (a) to determine the extent of droplet mixing on extraction and selectivity and (b) to extend the simulation models developed to analyze efficiency and selectivity in multiple stage extractors of various configurations. Research progress towards the first objective is largely developmental. Equilibrium and kinetic data are being developed for the Co(II)/NO/sub 3//sup -/-Di(2-ethyhexyl) phosphoric acid. A specially designed Lewis cell has been fabricated to obtain the kinetic data. The reactor provides for sampling of either phase in situ to obtain instantaneous reaction rates. The construction of the specially designed capillary spectrophotometer is in progress for obtaining bivariate drop size concentration data. The kinetic, equilibrium, and bivariate data will be employed with stochastic simulation models to determine and quantify the extent of droplet mixing on conversion and selectivity.
