This paper deals with the surface characteristic of pyrrhotite bio-oxidized by Acidithiobacillus ferrooxidans. Large amounts of jarosite and element sulfur were determined in the bio-oxidation processe of pyrrhotite. More complicatedly, biofilm exists on the surface of pyrrhotite. This type of structured community of A. ferrooxidans was enclosed in the extracellular polymeric substances (EPS), and covered with the deposition generated in the bio-oxidation processe of pyrrhotite.
