The Smelting of Sulfide Ores of Copper in Preconquest Peru

With a simple sulfide ore like chalcocite, once the sulfur has been burned off as sulfur dioxide (SO2) and the copper sulfide thus converted to copper oxide, the oxide can be reduced with charcoal, described above (Thompson 1958: 4). How the Indians happened on the roasting of sulfide ores may never be known.

Chalcocite - an overview ScienceDirect Topics

Copper is most commonly present in the earth's crust as copper–iron–sulfide and copper sulfide minerals, for example, chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), and chalcocite (Cu 2 S). The concentrations of these minerals in an ore body are low. Typical copper ores contain from 0.5% Cu (open-pit mines) to 1−2% Cu (underground mines).Copper is most commonly present in the earth's crust as copper–iron–sulfide and copper sulfide minerals, for example, chalcopyrite (CuFeS 2), bornite (Cu 5 FeS 4), and chalcocite (Cu 2 S).
