    Selective Flocculation Of Fine Coal With Hydrophobic

    Feb 01, 1993 The bacterium Mycobacterium phlei is highly hydrophobic and negatively charged. It has specificity for selective adhesion to fine coal particles, mainly due to hydrophobic interaction. However, it does not attach to pyrite and ash-forming minerals present in the coal matrix. Results have shown that this bacterium is an excellent flocculant for fine coal. Not only are the coal particles visibly ...
