Pesic, B; Oliver, D J

The objective of this project is to provide the fundamental information on the mechanisms of bacterial leaching of pyrite. The knowledge of how bacterial leaching of pyrite functions is essential for design and development of a technology for coal cleaning with bacteria. The features of major electrochemical techniques will be examined to find out if any of them can provide a diagnostic information on the mechanisms of related reactions. This reporting period is related to the study on the effect of silver ions on activity of Thiobacillus ferrooxidans. This activity was monitored by measuring the redox potential of solution during oxidation of ferrous ion to ferric. 14 refs., 6 figs., 1 tab.
