Fe-hydroxysulphates from bacterial Fe2+ oxidation

Eneroth, Erik LU and Koch, CB (2004) 27th International Conference on the Applications of the Mössbauer Effect (ICAME 2003) 156-57(1-4). p.423-429
Abstract
Precipitates formed due to Fe(II)-oxidation catalysed by Acidithiobacillus ferrooxidans between pH 1.6 and 3.2 have been studied by powder X-ray diffraction, infrared spectroscopy and Mossbauer spectroscopy. The precipitates consist of well crystalline, ammonium-containing jarosite at pH 1.6, and mixtures of jarosite and poorly crystalline schwertmannite at pH 2.5 and 3.2. At low temperatures ( 10 and 20 K) the components of the two phases overlap strongly. Jarosites ordered (c. 45 K - defect antiferromagnetic) at temperatures well below the ordering temperature for schwertmannite (c. 80 K at pH 3.2 and c. 70 K at pH 2.5). Thus thermoscans measured between 100 and 10 K facilitates characterization of these two minerals when occurring in... (More)
