Deep abiotic weathering of pyrite
Getting rid of fool's gold Pyrite, also called fool's gold, is an iron sulfide mineral that is very commonly found in rock but is almost nonexistent in sediments today.

Pyrite is a common mineral in sedimentary rocks and is widely distributed in a variety of different morphologies and sizes. Pyrite is also widely distributed in the Es3x shale of the Eocene Shahejie Formation in the Zhanhua Sag, Bohai Bay Basin.

Morphology dominated rapid oxidation of framboidal pyrite
The rapid oxidation of framboidal pyrite is conventionally attributed to its fine grain size. However, the effect of the crystal facets of the microcrystals in the framboids on the oxidation process has been overlooked. We synthesised pyrite monocrystals

DFT Study into the Influence of Carbon Material on the Hydrophobicity of a Coal Pyrite Surface
From the macroscopic point of view, the hydrophilicity of symbiotic carbon pyrite is weakened overall compared to that of pure pyrite. It is very important to explain the impact of elemental carbon accreted on a pyrite surface on the surface’s ...

Study on Water Wettability Mechanism of Pyrite and Coal Surfaces Based on Density Functional Theory
Flotation is based on the difference of wettability of mineral surfaces. In order to study the water wettability mechanism of pyrite and coal surfaces, pyrite and perfect coal surface models were constructed. The adsorptions of water and oxygen molecules

Pyrite/H2O2/hydroxylamine system for efficient decolorization of rhodamine B
To improve the efficiency of the Fe(II)/Fe(III) cycle and continuous reactivity of pyrite, a pyrite/H2O2/hydroxylamine (HA) system was proposed to treat rhodamine B (RhB).
