The dissolution of copper scrap has been investigated as a possible approach to the production of copper chloride solutions for certain metallurgical purposes. The principal stages involved in the dissolution have been found to be (1) diffusion‐controlled attack of cupric ions on the surface of the copper, and (2) re‐oxidation of cuprous ions by oxygen. The effects of chloride concentration, acidity, temperature, agitation, metal surface area and oxygen partial pressure are described.
