Bioleaching and mineral biotechnology
Current Opinion in Biotechnology, 1993Abstract Advances in the bioleaching of sulfide materials, sulfur removal from fossil fuels, and mineral biotechnology are reviewed. Recent descriptions of acidophilic microbial communities and newly recognized bacterial species have revealed abundant physiological diversity in acid mine water environments that may have potential application in ...

Acidophilic microorganisms that oxidize iron and sulfur can be exposed to high temperatures in geothermal environments and in some heaps of ores and mine wastes. A variety of types with different optimum temperatures for growth are found across temperature gradients in the natural environments and may succeed one another as exothermic oxidation ...

Natural bioleaching has been taking place for almost as long as the history of the world, but it is only in the last few decades that we have realized that bioleaching is responsible for acid production in some mining wastes, and that this bacterial activity can be used to liberate some metals. The application of the bioleaching reaction for copper has
