| Abstract: | Three Thiobacillus ferrooxidans strains with strong arsenic resistance and capacity of sulfide ore decomposition, namely M1s, 1# and Malan, were used for a microbial oxidation and leaching experiment on DBF ore from Shimian County, Sichuan Province. The arsenic content and pH change in the microbial oxidation process and the optimum leaching conditions of gold were studied intensively. The change of the microbial oxidation process with time and the optimum leaching conditions of gold are given in the paper. |
| Keywords: | arsenic-bearing sulfide arsenic removal by microbial oxidation Thiobacillus ferrooxidans leaching rate of gold ore |
