This film "A Story of Copper" was produced by the Bureau of Mines in 1951, and informs viewers about the copper production process. It starts with the two different types of mining: surface strip mining and underground tunneling. These are explored in detail including the equipment needed and great footage of dynamite being placed. This is followed by the copper refining process, which includes a lot of grinding, sorting, purifying, and melting to achieve the purity needed for copper. This includes detailed footage of the equipment and the furnaces needed.
