    In case of chalcopyrite ores, which are more difficult to leach, new bioleaching technologies are currently under development in some places, such as Escondida mine in Chile (Gentina and Acevedo). Once the copper metal goes to solution, then solvent extraction and electrowinning techniques (Cu SX-EW) are employed to yield copper cathodes.
