(C) In the electrorefining process of copper,the impure copper acts as the anode and pure copper as the cathode. During electrolysis,more electropositive impurities like $Fe$,$Ni$,and $Zn$ dissolve into the electrolyte solution. Noble metals like $Au$,$Ag$,and $Pt$ are less reactive and do not dissolve; they settle down at the bottom of the electrolytic cell below the anode,which is known as anode mud.

When copper is purified by the electrorefining process,noble metals like $Ag$ and $Au$ are found in:
