copper processing
Molten copper being made into plates.
In the process of copper electrorefining, the electrolyte is an aqueous solution composed of copper sulfate and sulfuric acid.12
This electrolytic solution serves as the medium through which an electric current is passed to facilitate the purification of copper. During this process, copper is dissolved from the positively charged anode and deposited in a high-purity form onto the negatively charged cathode. Copper sulfate acts as the basic salt in this electrolytic refining process.13
