Arsenic (As) is a ubiquitous metalloid that is highly toxic to all living organisms. When grown
in As-contaminated soils, plants may accumulate significant amounts of As in the grains or …

Arsenic (As) is a toxic metalloid. Serious concerns have been raised in literature owing to its
potential toxicity towards living beings. The metalloid causes various water-and food-borne …

Microorganisms are abundant in many surface and near-surface geochemical
environments. They interact with arsenic through a variety of mechanisms, including …

Arsenopyrite and pyrite often coexist in metal deposits and tailings, thus simultaneous
bioleaching of both sulfides has economic (as well as environmental) significance. Important …

Abstract (Bio) Hydrometallurgy is a relatively economical and eco-friendly processing
technology for sulfide minerals. Sulfide minerals degradation at abandoned mine sites also …

The bio-oxidative dissolution of arsenopyrite, the most severe arsenic contamination source,
can be mediated by organic substances, but pertinent studies on this subject are scarce. In …

In this study, the mechanisms by which ferric iron promotes bioleaching of arsenopyrite by
the moderately thermoacidophilic strain Sulfobacillus thermosulfidooxidans YN-22 was …

The effect of jarosite generated from bio-oxidation on gold leaching in acidic thiourea
solution was studied, and the role of the oxalate additive was also investigated. The …

Arsenic is a critical environmental pollutant associated with acid mine drainage.
Arsenopyrite is one of the major arsenic sulfide minerals whose weathering lead to the …

The surface properties of arsenopyrite during chemical and biological oxidation were
investigated by synchrotron X-ray diffraction (S-XRD), X-ray absorption near-edge structure …
