Abstract

Chlorination of copper has distinctive physical and chemical properties, which makes it applicable in fields of mineral processing, material synthesis, and energy production. Chlorination technique for simultaneously extracting Ni and Cu from mixed oxide-sulfide copper‑nickel ore or selective chlorination for the removal of copper from copper slag was developed. Copper film is a promising material which can be produced through the “in situ” chlorination of copper by chlorine and copper deposition via reduction of Cu3Cl3 by hydrogen. The Cu-Cl thermochemical cycle for hydrogen production has significant potential because it does not generate greenhouse gas and requires lower energy consumption.
