Leaching is the solubilisation of metals from ores, as microorganisms are used to solubilise metals, it is popularly known as Bioleaching or Biological Mineral Leaching. It was used for the first time in the 18 th century in Rio Tinto mines for the extraction of copper from its ores. The microorganisms leach out the metal in the form of metal salt.

Biomining is mineral processing with microbes. Biomining is the process of using microorganisms (microbes) to extract metals of economic interest from rock ores or mine waste. Biomining techniques may also be used to clean up sites that have been polluted with metals. Valuable metals are commonly bound up in solid minerals. Some microbes can oxidize those metals, allowing them
