After mining, copper is produced by one of two process routes, pyrometallurgical dry or hydrometallurgical wet. smelting isrocess of heating and melting ore to extractetal like copper. refining refers to any process that increases the grade or purity of the metal.
Archeologists have also found evidence of mining and annealing of the abundant native copper in the upper peninsula of michigan in the united states dating back to 5,000 b.c. native copper was likely used first, as it did not require any process to purify it. it could have been hammered into shapes although it would have been very brittle.
