Electrorefining can be used. What you'd do it connect the impure crude copper bar at the positive terminal of a battery via wire. You'd connect a pure copper bar at the negative terminal via wire. At the first end mentioned, oxidation of copper occurs (after the impurities do) Cu (s) -> 2e- + Cu 2+. This is the anode. The electrons lost are transported through the battery to the other end to negatively charge up the cathode. The Cu2+ ions get attracted to it and reduce to pure copper Cu2+ + 2e- -> Cu (s) (before the impurities do).
