Ion exchange and sorption have found widespread use in the recovery, separation and purification of metals; the most notable advances have occurred with uranium, precious metals and the platinum group metals. Separation processes based on sorption are not energy intensive and can be applied to low grade mineral resources and to by-product recovery of valuable metals. In this respect, the process technology is similar to solvent extraction which has been so successfully applied to the recovery and purification of base metals such as copper. New developments have included the advent of successful continuous ion exchange technology, the development of new selective polymeric ion exchange materials and the fabrication of durable adsorbents such as activated carbon. This volume provides an overview for researchers investigating new separation processes and those in the hydrometallurgy industry looking for means of improving commercial efficiency of the existing processes.
