Gold solvent extraction has been used to recover gold by analytical chemists for about one century. Due to the potential advantages of solvent extraction technology over present zinc-dust cementation and carbon-adsorption procedures in gold recovery, metallurgists have paid much attention to the study of gold solvent extraction in recent years. Some promising extraction systems were proposed and studied. Recently some new progress in gold solvent extraction have been achieved in our research group. In the mechanism study on quaternary amine extraction system, a supramolecular structure model based on hydrogen bonding between modifier and Au(CN)2- was proposed. For the stripping of quaternary amine extraction system, a procedure based on NaClO4 solution and saturated KCl solution was reported.
