    The separation of cadmium from zinc with a synergistic

    01-07-2005· The removal of cadmium from zinc sulphate solution in zinc refining can be carried out by cementation with zinc powder. An alternative process to cementation is solvent extraction (SX). The removal of cadmium by solvent extraction has several advantages over zinc powder cementation, which include potential lower capital and operating costs and less environmental pollution.
