Mechanism of microorganism regulating mineral surface properties

In the course of biological mineral processing,the biological actions occur mainly on mineral surface.The electrical property,hydrophobic property and wettability of mineral surface can be modified by microorganism,which create favorable conditions for biological mineral processing.Interface effects come down to a series of complex physical and chemical process between mineral and microorganism.Study the electrostatic force,specific adsorption and adhesive attraction between mineral and microorganism,as well as energy substances requisite for some types of microorganism.Investigate the characteristics that microorganism act on mineral surface and change law of mineral surface proferties.The results provide the theoretical reference for biological modification of mineral surface.
