Hi Does anyone know what process(es) are used to extract native Copper. Does one still use electrolytic processes even if the native copper is in substantial amounts ? Realy keen to know as I cannot seem to find anything on this topic on the web. All the article are about sulphides and oxides and electrolysis but NOTHINg about native copper. Anyone ?
