Interior of a section of the Tacoma Smelter taken in March of 1919. This was the copper refinery. Copper anodes from the smelter were inserted between copper cathodes in a copper-sulfuric acid bath. Copper was transferred from the anode to the cathode. The two raised frameworks in the photograph's middle were stands for "slapping copper starter sheets" before they were inserted into the bath as cathodes. The American Smelting & Refining Co., better known by its acronym, ASARCO, was a major employer in Ruston for nearly a hundred years. G32.1-023 (Additional information provided by a reader)
