Corrosion and Electrochemical Oxidation of a Pyrite by Thiobacillus ferrooxidans.
The oxidation of a pure pyrite by Thiobacillus ferrooxidans is not really a constant phenomenon; it must be considered to be more like a succession of different steps which need characterization. Electrochemical studies using a combination of a platinum electrode and a specific pyrite electrode (packed-ground-pyrite electrode) revealed four steps in the bioleaching process. Each step can be ide...
متن کاملOxidation of Pyrite and Marcasite by Thiobacillus ferrooxidans Bacteria
This paper reports results of studies on the influence of the crystallographic mineral structure on the process of pyrite and marcasite leaching. Kinetic studies show that the crystallographic structure of minerals like FeS2 type does not influence the efficiency of the process.
متن کاملKinetics of Iron Oxidation by Thiobacillus ferrooxidans.
A statistical relationship between the rate of ferric ion production by a strain of Thiobacillus ferrooxidans and various levels of cell concentration, Fe concentration, Na concentration, and temperature was studied by a direct colorimetric method at 304 nm. The relationship was linear (90 to 93%), cross-product (3 to 4%), and quadratic (1 to 2%). The levels of cell concentration and Fe concent...

15 صفحه اولSelective Adhesion of Thiobacillus ferrooxidans to Pyrite.
Bacterial adhesion to mineral surfaces plays an important role not only in bacterial survival in natural ecosystems, but also in mining industry applications. Selective adhesion was investigated with Thiobacillus ferrooxidans by using four minerals, pyrite, quartz, chalcopyrite, and galena. Escherichia coli was used as a control bacterium. Contact angles were used as indicators of hydrophobicit...
