The copper concentrate is trucked to on-site railway terminal and reloaded for further transport by rail to the Boliden Rönnskär smelter in Skelleftehamn. The plant produces a final concentrate containing 20-23% copper with gold, silver and molybdenum. Copper recovery is at 85-95% while silver and gold is at 65% and 50%, respectively.
Processes: copper mining and production. Copper is found in natural ore deposits around the world. This page explains copper mining: the production route taken from ore-containing rock to a final product that is the highest-purity commercial metal in existence and used in a wide variety of applications essential to modern living.
The mine also illustrates the history of world and U.S. copper between 1907 and 1938. The rise and decline of Kennecott copper brought a parallel pattern in Alaska's mineral production. It also illustrates a chapter in American economic and business history: the discovery of one of the world's richest copper deposits which led to the ...
