Solution

Copper sulfate is used mostly for the Electrolytic refining of impure copper. The pure copper metal dissolves out from the copper anode [impure copper block] and the Cu²⁺ ions formed in solution at the anode are deposited at the cathode [the thin pure sheet of copper]. The impurity present in impure copper anode settle down as anode mud or slime which contains insoluble gold and silver. Impurities such as iron, zinc etc ionize and dissolve in the electrolytic copper sulfate solution.
