Interactions of mimic weathered pyrite surfaces (FeS2) with acidic culture media (0 K): An approach for (bio)leaching applications
(Elsevier Science, 2018-12)
In biohydrometallurgical processes, a mineral exhibits different oxidation phases due to the system's heterogeneity, especially in heap leach pads. Oxidation chemically modifies the mineral surface altering its interface, ...

Mechanochemically synthesized pyrite and its electrochemical behavior as cathode for lithium batteries
(Springer, 2019-06)
This study presents a simple and scalable synthesis of pyrite (FeS2) starting from S and Fe powders, which involves high-energy ball milling of precursor powders followed by a thermal treatment. The formation of the desired ...
Patagonian salt marsh soils and oxidizable pedogenic pyrite: solid phases controlling aluminum and iron contents in acidic soil solutions
(Springer, 2018-12)
The sulfidic materials present in salt marshes could be oxidized forming sulfuric acid, increasing the toxic levels of both Al and Fe available to plants. The objectives of this study were: (a) to evaluate the mechanism ...
Identification of surface processes in individual minerals of a complex ore through the analysis of polished sections using polarization microscopy and x-ray photoelectron spectroscopy (Xps)
(MDPI, 2018-09-28)
Understanding the changes of a mineral during ore processing is of capital importance for the development of strategies aimed at increasing the efficiency of metal extraction. This task is often difficult due to the ...
Iron biogeochemistry in Holocene palaeo and actual salt marshes in coastal areas of the Pampean Plain, Argentina.
(Springer, 2016-02)
In salt marshes, the hydrodynamics and the availability of iron, organic matter and sulphate, influence the formation and/or dissolution of iron sulfides and iron oxyhydroxides. Therefore, they constitute key factors ...
