Anaconda smelter, Montana. Anaconda Copper Mining Company. Poling in the refining furnace. Wooden poles are plunged into the molten copper; there is a great evolution of gases when this is done and the excess oxygen combines with the carbon of the wood and passes off as carbon monixide. This refining of blister has a stronger affinity for the impurities in the charge than it has for copper
