Abstract

"In one part of this research, spontaneous electrochemical redox reactions in conventional organic solutions commonly used in solvent extraction were demonstrated. In these reactions, the more noble metal is reduced while the less noble metal dissolves simultaneously. This technique was successfully applied in metal recovery or impurity separation in laboratory tests using synthetic and commercially produced solutions. The second use of the process was in depositing metal seed layers on metallized wafers for use in chip manufacture. The patented process in the first application, called galvanic stripping, has been demonstrated on batch and continuous levels to separate iron from a sulfate medium using DEHPA"--Abstract, page iv.
