This is not enough to make it commercially viable to extract the rock. copper mines are only set up where there is more than 5 kg of copper per tonne of rock (0.5% by mass). ideally, the figure should be closer to 2%. the world’s largest copper ore deposits are found in.
When reviewing methods of eliminating copper from gold ores we see that several methods have been suggested to eliminate copper from ores prior to cyanidation. preliminary extraction of the copper with sulphuric or sulphurous acids may be applicable to ores containing oxidized copper minerals such as malachite, azurite and chrysocolla but these acids have but little effect on sulphide copper.
