purification of copper by electrolysis metal extraction

The metal copper can be easily extracted BUT copperrich ores are becoming scarce so new methods of extracting copper are being developed to exploit low grade ores. A low grade ore is one with low concentrations of copper and research is going on to try and exploit waste material left over from processing high grade ores.
