The bacteria essentially transform solid gold into a highly soluble gold compound and then back again. If humans could mimic the process, it would be possible to take ore with a very low percentage of gold, transform the precious metal into a water soluble version of itself, dissolve it from the rock and then voila transform it back

Bacterial heap leaching of refractory gold/sulphide ores

Gold occurs as free gold (40%) and gold locked in pyrite and arsenopyrite (60%). Gold recovery in alkaline cyanide heap leaching after bacterial leaching was 74 % (compared with 24 % without bacterial heap leaching), but the acid consumption to achieve this recovery was very high at 250 kg/t of ore.

Bioleaching is the use of bacterial microorganisms to extract precious metals, such as gold, from ore in which it is embedded. As an alternative to smelting or roasting, miners use bioleaching when there are lower concentrations of metal in ore and they need an

Gold  Geoscience Australia

Gold Geoscience Australia

Free milling ore is the name for when gold can be recovered by crushing, grinding and cyanidation (treatment with a dilute cyanide solution) without additional processing. In refractory ore the gold is locked in sulphide minerals, so to achieve satisfactory levels of gold recovery additional processing is required before cyanidation.
