| titleOfInvention | Method for pretreating arsenic-containing gold ore by synergistically strengthening bacterial oxidation |
| abstract | The invention discloses a method for pretreating arsenic-containing gold ore by synergistically strengthening bacterial oxidationThe method comprises the following steps: adding the finely ground arsenious gold ore into the culture medium, injecting Thiobacillus ferrooxidans, and adding Cu 2+ Ions and sodium oxalate are added to adjust the pH value of the ore pulp to acidity, and biological oxidation pretreatment is carried out on the arsenic-containing gold ore. The invention adds Cu into ore pulp of arsenic-containing gold ore 2+ Ions and sodium oxalate through Cu 2+ The synergistic effect of the ions and the sodium oxalate fundamentally greatly reduces the generation of passivation substances in the biological oxidation process, shortens the biological oxidation period by more than 2 days, improves the leaching rate of arsenic by more than 10 percent, has low price, high efficiency, simplicity and easy operation, and solves the technical problems of low oxidation rate and long oxidation period of the existing method for pretreating the gold ore containing arsenic by the biological oxidation method. |
