    What is Bioleaching with pictures

    About 20 percent of the worlds extracted copper comes from bioleaching. 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 efficient.
