Meanwhile a Canadian firm, BacTech Mining Corporation, which sells a bioleaching process for gold extraction, has set up a new division to apply the technology to mining waste. At the town of Cobalt in Canada it plans to remove toxic elements such as arsenic from old silvermine tailings and extract cobalt, nickel and silver.
Microbial mining of copper sulphide ores, has been practiced on an industrial scale since the late 1950s. Since then, advances in microbial mining and the role of microorganisms involved in solubilization of metals have assumed commerical importance.
