Abstract
A process for the selective extraction of copper chlorides from aqueous solutions by forming a solid addition compound of cuprous chloride with an unsaturated aliphatic hydrocarbon having from 2 to 6 carbon atoms, separating and decomposing the addition compound and recovering solid cuprous chloride. The process can also be used for the separation of copper chlorides from silver-chloride. The process may be applied to the recovery of copper from hydrometallurgical process solutions.
