  • Producing Copper Nature's Way: Bioleaching
    SummaryExamples of Current Industrial Bioleaching OperationsBackgroundChemistry of BioleachingMicrobiology of BioleachingLeaching MethodCostsResearchConclusionsBioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals. It is the leaching of sulfide minerals that distinguishes bioleaching from conventional acid See more on copper

  • Biomining Wikipedia

    Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes or fungi. These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons. It was discovered in the mid 1900s that microorganisms use metals in the cell.
