Powder, chalcopyrite in the new ,powder, electrode system was held at 0.45 V in the presence ,of copper, ion and sulfuric acid media followed by an application of potential in the anodic direction. Besides the chalcopyrite oxidation peak, a small peak resulted at ~0.55 V; this peak corresponds to reduced chalcocite, because it occurs at the same potential as the chalcocite oxidation peak..
