How copper dump leaching works

If copper recovery depends on (1/d p) and the copper leaching rate depends on (1/d p) 2, leaching of ROM ore in dumps should be impossible, or at least so slow and marginal as to not be profitable.And yet dump leaching of copper secondary sulphides is practiced widely, with good recoveries and at rates rapid enough to be …
