Workers at the Anaconda Copper Mining Company in Anaconda, Montana, engage in a crucial step of copper refining in September 1942. They plunge wooden poles into a furnace of molten copper, where oxygen reacts with carbon from the wood, producing carbon monoxide. This process separates impurities from the copper, showcasing industrial techniques of the time.
