Abstract：A yellow ochre-colored jarosite was synthesized by bacterial oxidation of ferrous ion by Thiobacillus ferrooxidans at 28 ℃ and 1 atm. The identification of the bacterially oxidized ion precipitate was carried by SEM, XRD, FTIR and chemical analysis. Results showed that resting T. ferrooxidans cells could completely oxidize ferrous ions to ferric ions in FeSO4-K2SO4-H2O system at pH 2.5. In the presence of suitable monovalent K+ and excess sulfate, the yellow precipitate was produced from bacterially oxidized iron solutions. The subsequent characterization showed that it was high-quality jarosite without by-product such as amorphous ferric hydroxysulfates.
