| Abstract: | A strain of Acidithiobacillus ferrooxidans(A.f.) isolated from the acid mine drainage(AMD) of the Dabaoshan mine and a mineral galena was used to study its bio-oxidation of galena.Experiments were designed to compare the differences between abiotic oxidation and bio-oxidation of galena at pH2.00 and 3.00 with or without Fe2+.The concentrations of cations such as Pb2+,As5+ and Cd2+,anion SO2-4 and pH values during the experiments were measured,the solid experimental results were analyzed with XRD,and changes... |
