extraction of metals. extraction of copper.. copper is sometimes found as native metal.. copper ores include copper oxide and copper sulfide. copper oxide can be reduced by reaction with carbon.. some copper ores may contain only small amounts of copper. these are called low grade ores and have less than copper but they are still used because copper is so valuable.
the early development of copper probably was most advanced in egypt.as early as 5000 bce, copper weapons and implements were left in graves for the use of the dead.definite records have been found of the working of copper mines on the sinai peninsula about 3800 bce, and the discovery of crucibles at these mines indicates that the art of extracting the metal included some refining.
