  • Bioadsorption alteration of iron sulfide surfaces
    Patent number: 4269699
    Abstract: The sulfide surfaces of finely-divided impure iron sulfide-containing minerals such as pyritic ores or coals are rendered hydrophilic by the adsorption of conditioned, inorganic sulfide-oxidizing bacteria. This adsorption of conditioned bacteria occurs in a short time to render the surfaces hydrophilic and allows these altered sulfide particles to be separated from hydrophobic solids by flotation, oil-agglomeration or the like. This bioadsorption process has particular applicability to pyritic coal beneficiation.
