摘要：
A solvent extraction procedure using the bifunctional extractant Kelex 100(R) is developed for copper transfer from hydrochloric acid into sulphuric acid medium with a view to the subsequent recovery of copper by electrolysis. The procedure involves the following steps: extraction of copper, scrubbing of chloride ions, stripping of copper and conditioning of extractant. The mechanism and kinetics of copper transfer from the one to the other functional group of the bifunctional extractant Kelex 100(R) was studied in the step of chloride ion removal. A model involving a stagnant and a mobile reaction zone was developed to describe the diffusion regime created in the Lewis cell.
