Аннотация: The industrial-level tests prove efficiency of Pseudomonas Japonica bacteria in production of copper-molybdenum bulk concentrate. Using scanning electron microscopy, it is found that adsorption of Pseudomonas Japonica bacteria takes place at the points of xanthate attachment. The infrared spectroscopy analysis shows that after treaПоказать полностьюtment with the bacteria, C-O and C=S bonds vanish while valence and deformation vibrations in CH3- and CH2 groups become less intensive, which may be reflective of desorption of xanthate from the mineral surface.
