The Morphological Characteristics of Authigenic Pyrite Formed in Marine Sediments
Pyrites are widely distributed in marine sediments, the morphology of which is applied as a proxy to infer the redox conditions of bottom water, and identify diagenetic stages and hydrocarbon leakage activities.

In the process of chalcopyrite–pyrite flotation, depression of pyrite is of great significance. In this study, tannic acid (TA) was used to replace traditional inorganic reagents for depression of pyrite under the low-alkalinity condition, and the ...

SIMS discovers invisible gold in pyrite from the high-grade seafloor hydrothermal deposits in the Higashi-Aogashima knoll caldera, Izu-Ogasawara arc, Japan [PDF]
Seafloor hydrothermal deposits with extremely high concentrations of gold were recently discovered in the Higashi-Aogashima knoll caldera hydrothermal field, Izu-Ogasawara arc Japan. We report here the discovery of ultra-high concentrations of “invisible

Insights Into Divergent Mechanisms of Pyrite Oxidation by Indigenous Fungi From Mine Tailings [PDF]
Fungi can oxidise pyrite, a process which has potential implications for metal bioleaching and acid mine drainage formation. However, this capacity has been demonstrated primarily using only a few model fungal strains.

Sedimentary Mercury Enrichments as a Tracer of Large Igneous Province Volcanism
Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Research progress in the electrochemical behavior of pyrite during grinding and flotation
Metal sulfides are highly desirable owing to their semiconductor properties promoting electrochemical reactions for sulfide flotation. As the most common sulfide mineral, pyrite is found in coal and can contain a small amount of gold.

Comparison of different approaches for bioleaching of a granite-type uranium ore [PDF]
Uranium bioleaching has been rapidly developed in China during recent years. However, some problems during bioleaching, such as low uranium leaching efficiency for rocks lacking pyrite, remain to be solved.
