In South America, copper objects were being produced along the northern coast of Peru as early as 500 B.C., and the development of copper metallurgy was well advanced by the time the Inca empire fell to the conquering Spanish soldiers in the 1500s. In the United States, the first copper mine was opened in Branby, Connecticut, in 1705, followed ...

copper – an intermediate product from the recycling of electronics. The result is known as blister copper, which has a copper content of 97-98 per cent. The blister copper is then processed in an anode furnace to reduce its oxygen content. This increases the purity level to 98-99 per cent and the copper is then cast to form anodes.
