Exploitation of Bacterial Activities in Mineral Industry ...

The most important group of bacteria which are involved in sulfide minerals leaching are the acidophilic Thiobacilli which belongs to the family Thiobacteriacrae. They have the ability to use the oxidation of inorganic sulfur and its compounds to produce energy for growth. They are, therefore, referred to as chemolithotrophs.

BACTERIA MINE GOLD - ABC

In the 90s, 30% of the copper produced in the US is mined by bacteria. The world's largest bacteria plant is planned for Wiluna in Western Australia. The bacteria are expected to process some 400,000 tonnes of gold sulphide per year. Gold-mining has always used rather toxic chemicals to extract the gold.
