✦ Synopsis

Abstract

A packed‐bed electrochemical method is presented for the removal of copper from scrap steel. The method is based on the principle that at certain potentials, steel can be passivated in a suitable electrolyte, whereas copper dissolves anodically. A rotating hemispherical electrode was used to determine the polarization curves of copper and mild steel in various electrolytes. Extraction tests were carried out with an electrochemical cell composed of a cathodic carbon packed bed and an anodic bed packed with synthesized steel scrap.
