  • Bioleaching Process - Mining Fundamentals

    Bioleaching, or microbial ore leaching, is a process used to extract metals from their ores using bacterial micro-organisms. The bacteria feed on nutrients in the minerals, causing the metal to separate from its ore. The metals commonly extracted using this process include gold, silver, zinc, copper, lead, arsenic, antimony, nickel, molybdenum cobalt, and uranium.

  • Bacterial leaching of ores and other materials

    Bacterial leaching is a very slow process. Around 3 to 10% of the copper content is leached out of a low grade sulfidic copper ore per year. So dumps may be operated 10 to 20 years. But on the other hand dump leaching is a simple and cheap method. It needs only a little capital investment, has low operating costs, requiring-little labor, and is ...

    Once solvent extraction proved to be a cost-effective way to purify and concentrate copper from leach liquors, copper ore leaching processing began to regard leaching as a much more important source of copper. Two early advances in leaching include the distribution of large drops of leach solution over the ore at Baghdad in 197019 and the use of drip irrigation by Johnson Camp in 197620.
