the extraction of metals from iron ores

  • Methods of Metal Recovery by Microorganisms 2 Methods

    It may be noted that removal of iron is desirable prior to the actual process of leaching for other metals This can be done by using the organism Thiobacillus ferrooxidans which can precipitate iron under aerobic conditions Bioleaching is also useful for the removal of certain impurities from the metal rich ores.
