It is also the oldest metal known to man and was first discovered and used about 10,000 years ago.

In addition to new copper being mined, copper recycling is an important component as the red metal does not degrade or lose its chemical and physical properties during the recycling process. The International Copper Study Group estimated that 33 of the worlds copper consumption came from recycled copper in 2017.
Low-grade ore is ball-milled before being agglomerated and dump-leached to recover its copper content. The Detroit Copper Company started mining at Morenci, 16km south of Silver City, Arizona, in 1872.
