Review of recent solvent extraction studies for recovery of silver from aqueous solutions

This work is focused on the recent advances, mainly achieved during the pas t ten years, on the recovery of silver using solvent extraction. Within the general purposes usually associated with the use of solvent extraction, re search on the selective recovery of this valuable element from aqueous solu tions is particularly emphasized, as it can be useful for potential hydrome tallurgical applications. In addition, work devoted to a better comprehensi on of extraction reactions in given systems is also a value adding, deservi ng a special mention in this review. The information provided is systematic ally classified according to the general structural type of the extractants involved, the type or types of atoms in the extractants directly responsib le for metal extraction being, whenever possible, highlighted.
