Chalcopyrite also known as copper pyrites and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining e.g.Oct 05, 2016 Deposits of iron pyrites often contain enough copper to make them valuable as copper ores, and sometimes gold and silver add to the value of the ore but the presence of other sulphides may decrease the value. Galena, zinc blende, stibnite, and mispickel are detrimental, if present in the ore.Copper and its alloys, such as brass, are used for jewellery and ornaments.
