ÐShewanella putrefaciens CN32 reduces Fe(III) within two illites which have different properties: the Fithian bulk fraction and the <0.2 mm fraction of Muloorina. The Fithian illite contained 4.6% (w/w) total Fe, 81% of which was Fe(III). It was dominated by illite with some jarosite (~32% of the total Fe(III)) and goethite (11% of the total Fe(III)). The Muloorina illite was pure and contained...

In this work, a mineralogical study and thermal decomposition analysis of jarosite residue sample from zinc plant were carried out. The showed that the is mainly composed four components, including jarosites, sulfates–hydroxides, sulfides spinel. distribution relevant metallic elements in these components was characterized using sequential extraction process. X-ray diffraction results AFe3(OH)6...

A fundamental problem related to the paleoenvironmental study of early Earth rocks and minerals, and astrobiological exploration of planetary materials (e.g., asteroidal and Mars meteorites, Martian rocks) is not only recognizing and quantifying carbon-related compounds that may be present but also differentiating those molecules formed abiotically from those generated by extinct or extant life...

Reducing the potential leaching of Mo and Ni from fly ash (FA) petroleum coke is an increasingly important issue as Asia Europe’s demand expected to drastically intensify continuing urbanisation technological innovation demands ever more electricity. In present study, we investigated coal combustion products (CCP) a large coal-fired power station fed with 56:44 coal/petroleum blend. Results rev...

The search for in situ organic matter on Mars involves encounters with minerals and requires an understanding of their influence on lander and rover experiments. Inorganic host materials can be helpful by aiding the preservation of organic compounds or unhelpful by causing the destruction of organic matter during thermal extraction steps. Perchlorates are recognized as confounding minerals for ...
