How do you make pure copper?

Pure copper can be made by electrolyzing a copper sulfate solution using copper electrodes. During this electrolysis process, copper ions in the solution migrate towards the negative electrode and deposit as solid copper, resulting in pure copper being formed. It is important to use high-purity chemicals and maintain controlled conditions to ensure the purity of the final copper product.
