Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.. As in all mining operations, the ore must usually be beneficiated (concentrated).

Mining and concentrating. The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified.In this case they are merely shattered by explosives and then piled into heaps for extraction by cyanidation (see below).

Construction of the Mill building originally began in 1909; copper ore was crushed and concentrated in this building until the mines closed in 1938. Between 1911 and 1938, nearly $200 million worth of copper was processed at the Mill. At the peak of operation, approximately 300 people worked in the mill town and 200-300 in the mines.
