Bacterial and chemical leaching of gold-bearing ore from the shokpar deposit by acidithiobacillus ferrooxidans culture

Abstract

BACTERIAL AND CHEMICAL LEACHING OF GOLD-BEARING ORE FROM THE SHOKPAR DEPOSIT BY ACIDITHIOBACILLUS FERROOXIDANS CULTUREAnnotation. The periodic mode of bacterial-chemical leaching of gold-bearing ore from the Shokpar Deposit using the A. ferrooxidans culture was studied under laboratory conditions. Have been performed previous steps prior to the leaching process, such as culturing of Acid.ferrooxidans microorganisms, granulometric analysis of ore composition from the Shokpar Deposit. During 13 days of the oxidation process and when setting the optimal temperature and humidity, it was possible to achieve the actual value according to the test results -0.116 mg/l gold.

Evaluation of the Effect of Temperature on the Ore Leaching Process Relevance

“…The hanging (northern) side of the overthrust is dominated by polymictic and volcaniclastic sandstones with facially wedged extended lenses and layers of conglomerates. These rocks are crumpled into relatively small isoclinal folds [3] Figure 1.…”
