biomining

  1. use of organisms to promote the LEACHING (solubilization) of metals from their ores.
  2. use of organisms, such as BACTERIA and PLANTS, to accumulate metals, for example gold and silver, from mine tailings. The metals can then be recovered from the cells of the organism.

Chaney says biomining is the use of plants to mine valuable heavy-metal minerals from contaminated or mineralized soils, as opposed to decontaminating soils.
One of the hopes of the research cruise is that new hyperthermophiles will be discovered that leach mineral sulfide ores in the 80 [degrees] C to 100 [degrees] C range, and cultivated to improve the economics of biomining. A great advantage of biomining is that it can have less impact on the environment than traditional minerals processing.
