Applications of Chlorination of Copper: Separation

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

Applications of Chlorination of Copper: Separation

Selective chlorination for the extraction of copper and the upgrading of lean minerals can be achieved by controlling reaction conditions such as the temperature and/or the amount of the chlorinating agent. The resulting copper removal rate of 84.34% is obtained under the optimum conditions [5]. Pickles [6] conducted a study about thermodynamic analysis of selective chlorination of the arc

COPPER HYDROMETALLURGY AND EXTRACTION FROM CHLORIDE

Copper extraction with trialkyl amines rises when the acidity of the aqueous phase and the chloride content increase. Thus, the stripping is possible with solutions of low acidity and low chloride concentration. Chelating agents, such as hydroxyoximes and P-diketones extract copper cations. *>3 in this case, the bidentate ligands displace both waters of hydration and co-ordinated chloride ions
