Methods of dissolving copper into electrolytic solutions, such as solutions comprising nitrogen compounds, by supplying an anodic current to a copper or copper-containing metal that is in contact with an electrolytic solution comprising a nitrogen compound (such as 2-hydroxyethylamine) and carbon dioxide. Anodic current may be provided by, for example, galvanic coupling with a material having a more positive reduction potential in the electrolytic solution (or given the system of electrolytic solutions) than copper, and/or by applying an impressed anodic current to the copper or copper-containing metal. Separate reaction vessels may be employed to house a first copper metal and a second cathode metal, as well as the electrolytic solutions associated with each. |
