Jarosite pseudomorph formation from arsenopyrite oxidation using Acidithiobacillus ferrooxidans
(Elsevier B.V., 2010-09-01)
In this work, the oxidizing action of a native strain type A. ferrooxidans on a sulphide containing a predominance of arsenopyrite and pyrite has been evaluated. Incubation of the A. ferrooxidans strain in flasks containing ...

Solubility of sodium-jarosite and solution speciation in the system fe(iii)-na-h2so4-h2o at 70 degrees c
(ELSEVIER SCIENCE BV, 2007)
The aim of this work was to study the formation and chemical equilibrium of sodium-jarosite in synthetic Fe(III)-Na-HSO4-H2O solutions at 70 degrees C. Solutions were prepared adding sodium as NaOH and ferric iron as ...

Jarosite versus Soluble Iron-Sulfate Formation and Their Role in Acid Mine Drainage Formation at the Pan de Azúcar Mine Tailings (Zn-Pb-Ag), NW Argentina
(Open Access Mining & Mineral Processing Journal, 2014-05)
Secondary jarosite and water-soluble iron-sulfate minerals control the composition of acid mine waters formed by the oxidation of sulfide in tailings impoundments at the (Zn-Pb-Ag) Pan de Azúcar mine located in the Pozuelos ...
Analogy between the spectral signature of the jarosite from the pinchollo area in peru and from the meridiani planum on mars and recognition of the mineralization process
(UniandesGeocienciasFacultad de CienciasDepartamento de Geociencias, 2020)
This study tries to establish a comparison between environments hosting the mineral jarosite on Earth and Mars. In order to establish a comparison and possible analogy between the environments of these planets, the objective ...
Raman spectroscopy and x-ray fluorescence in molecular analysis of yellow blocks from the archeological site playa miller 7 (northern Chile)
(Sociedad Chilena de Quimica, 2013)
Yellow blocks from the archaeological site Playa Miller 7 (PLM7), on the coast of Atacama Desert in northern Chile, were analyzed by Raman spectroscopy and X-ray fluorescence (XRF) portable. Our results identify for the ...
Mineralogical control on arsenic release during sediment water interaction in abandoned mine wastes from the Argentina Puna.
(Elsevier Science, 2016-04)
The sulfide-rich residues of La Concordia mine, Argentina Puna, are accumulated in tailing dams that remainedexposed to the weathering agents for almost 30 years. In such period of time, a complex sequence of redoxand ...
