Oxidation of Ferrous Sulfate by Growing Cultures of Thiobacillus Ferrooxidans
Oxidation of ferrous iron in acid solutions is an important reaction producing soluble ferric iron. The oxidizing property makes the ferric ion one of the most useful reagents in hydrometallurgy. The ferrous iron oxidation kinetics of Thiobacillus ferrooxidans growing in batch culture was examined. T. ferrooxidans oxidized ferrous iron at pH 1.5 in the presence of oxygen and utilized carbon dio...
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 کاملGrowth of Thiobacillus ferrooxidans on Formic Acid.
A variety of acidophilic microorganisms were shown to be capable of oxidizing formate. These included Thiobacillus ferrooxidans ATCC 21834, which, however, could not grow on formate in normal batch cultures. However, the organism could be grown on formate when the substrate supply was growth limiting, e.g., in formate-limited chemostat cultures. The cell densities achieved by the use of the lat...
متن کاملdesulphurization of coal by using of thiobacillus ferrooxidans and thiobacillus thiooxidans bacteria
a new solution aiming at coal biodesulphurization has been developed based on the use of bacteria. the most frequently used species of bacteria for removal of inorganic sulphur compounds are thiobacillus ferrooxidans, thiobacillus thiooxidans and thiobacillus acidophilus. in this study the coal sample was decomposed initially and desulphurization experiments was carried out in pure and mixed cu...
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...
