The Behaviour of Low Arsenic Copper Anodes at High Current Density in Electrorefining [PDF]
Archives of Metallurgy and Materials, 2023 Arsenic is the only beneficial impurity for copper electrorefining through inhibiting anode passivation and the formation of floating slimes. The behaviour of copper anodes with different content of arsenic were studied at high current density (>280 A/m ...

Production of Metallic Titanium by Electrowinning in Molten Salts of Titanium Oxycarbide Anode
Materials Proceedings, 2021 The electrochemical behavior of Ti3+ in LiCl-LiF-TiF3 salt was investigated by cyclic and square wave voltammetries at 853 K. Both methods confirm the presence of a single reduction wave of Ti3+ ions to metal, at a potential of −2.3 V vs. Cl2/Cl−.
