  • Bacterial Leaching Extracting Gold from it's ore?

    Best Answer The basic idea behind bacterial leaching (also called bioleaching) is to introduce a bacteria to the metal ore that will naturally extract the metal and leave it in solution as waste which can then easily be extracted by other means. The bacteria do this to gain energy (you can think of it as food for the bacteria).
