Great Falls, Montana, Electrolytic copper refinery of Anaconda Copper Mining Company. Refining tanks in which the anodes of impure copper are refined by electrolytic means to the pure cathode copper. The anodes are placed in the tank as they are received from the Anaconda smelters; between these anodes are suspended starting sheets which are thin sheets of electrolytic copper; the cathode sheets remain in the tank until sufficient copper from the anode has been deposited on the cathode to give it a weight of approximately 170 pounds
