I would like to know the processes used to extract copper and gold from 
their ores by using bacteria leaching - how the micro-organisms liberate 
the metal from its ore and how the metal is then extracted from the 
mixture. I'd also want to know the advantages and disadvantges of bacteria 

leaching compare to traditional extraction methods and why it is used only 

as secondary process for copper but primary for gold. If details cannot be 

provided, please give website for information. Thanks.
