copper extraction refers to the methods used to obtain copper from its ores. the conversion of copper consists of a series of physical and electrochemical processes. methods have evolved and vary with country depending on the ore source local environmental regulations and other factors. as in all mining operations the ore must usually be
leaching or low grade sulphide ore that had to be mined in order to expose the underlying high grade sulfide ore. copper recovered from leaching low grade copper ores was considered a bonus and little effort had been made to fully understand the leaching process or to maximize copper recovery. while some fundamental leaching studies had
rare earth metals found on pacific's muddy floor and unusually poor in uranium ”sea mud can be brought up to ships and we can extract rare earths right there using simple acid leaching

copper leaching practices. for centuries small amounts of copper have been recovered from acid mine-drainage waters. in recent years the expansion of copper-bearing waste dump leaching for copper recovery has established a technological basis that is rapidly converting the art of copper leaching into a science.
bioleaching: introduction methods application copper microorganisms and processes! introduction to bioleaching: leaching process was first observed in pumps and pipelines installed in mine pits containing acid water. this process was later on employed for recovering metals from ores containing low tity of the metal. presently certain metals from sulfide ores and other ores are
