It is demonstrated that workable metallic copper can be produced by a simple two-stage process from chalcopyrite ore. This simpler process could have been in use before the more complicated multi-stage matte smelting process described in the historical documents on early technology. The simpler process would probably have been operable by any society in prehistory which possessed two-tiered pottery kilns. This simpler process may have been supplanted before recorded history by the matte smelting process because the latter permits recovery of precious metals (gold and silver).On a essayé de démontrer que le cuivre sous forme de métal peut être obtenu par un procédé simple comportant deux phases à partir du minerai de chalcopyrite. Cette tech...
