Compared to conventional extractive techniques, bacterial assisted leaching, also called
“biomining” is an eco-friendly technology that provides improved metal/solid separations …

Pyrite, FeS2, commonly referred to as “Fool's gold” is the most common sulfide in the Earth's
surface region. Not only is the mineral ubiquitous, but the reactivity of pyrite is of central …

Bioleaching of metal sulfides is effected by bacteria, like Thiobacillus ferrooxidans,
Leptospirillum ferrooxidans, Sulfolobus/Acidianus, etc., via the (re) generation of iron (III) …

Mismanagement of mine waste rock can mobilize acidity, metal (loid) s, and other
contaminants, and thereby negatively affect downstream environments. Hence, strategic …

The demand for metals is ever increasing with the advancement of the industrialized world.
On the other hand, worldwide reserves of high grade ores are close to depletion. However …

In spite of the environmental and commercial interests in the bacterial leaching of pyrite, two
central questions have not been answered after more than 35 years of research: does …

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

The Rı́o Pilcomayo rises on the Cerro Rico de Potosı́ precious metal-polymetallic tin
deposits of Bolivia, and flows in a southeasterly direction for ca. 600km to Bolivia's southern …

This paper reports the results of leaching experiments conducted with and without
Thiobacillus ferrooxidans at the same conditions in solution. The extent of leaching of ZnS …

The role of Thiobacillus ferrooxidans in bacterial leaching of mineral sulfides is
controversial. Much of the controversy is due to the fact that the solution conditions …
