[0002] In the production of electrolytic copper foil, the principle of copper dissolution is to convert metallic copper into Cu2+ dissolved in water, that is, Cu becomes Cu2+, and metallic copper becomes copper sulfate in aqueous solution. The copper dissolution process is to put the processed and qualified metallic copper into the copper dissolution tank as raw material. The raw metallic copper undergoes a series of chemical reactions with oxygen and sulfuric acid in the copper dissolution tank, and the solid metallic copper dissolves into a liquid copper sulfate solution.
