pyrometallurgical extraction of copper wikipedia

Prehistory of non-ferrous extractive metallurgy. In general, prehistoric extraction of metals, particularly copper, involved two fundamental stages: first, the smelting of copper ore at temperatures exceeding 700 °C is needed to separate the gangue from the copper; second, melting the copper, which requires temperatures exceeding its melting point of 1080 °C.
