Smelting is the basic process by which one produces workable metal from metal ores. The minerals in copper ores are reduced to copper through mixing carbon with the ore and heating the combination to about 1,100C. (This can be done directly with copper oxide ores. Copper sulphide ores are heated in contact with air first.)
