Thermal Behavior of Pyrite in the CO2 and N2 Atmosphere for Obtaining Pyrrhotite: A Magnetic Material [PDF]
Materials Research, 2018 In the southern of Brazil the coal is composed of a large amount of pyrite (FeS2), an environmental problem for this region because the pyrite turns a waste.

Sulfur isotope rations of sulfide minerals from the deposit of the Tsuchikura mine, Shiga Prafecture, Japan [PDF]
, 1998 Sulfur isotope rations of sulfide minerals in the ore specimens from the deposit of the Tsuchikura mine are distrib-uted in a range from -0.8 to 5.4%, mostly from +0.5 to 3.0%, close to the previous data (from +1 to +3%) by Miyake and Sasaki (1980).

Desulphurization of coals of different ranks in the presence of slimes by reverse flotation
Energy Reports, 2019 In this paper, the flotation separation of pyrite from sub-bituminous and meta-bituminous coals in the presence of slimes was investigated. The sub-bituminous coal and the meta-bituminous coal have significant differences in their surface properties ...

Pyrite trace element behavior in magmatic-hydrothermal environments: An LA-ICPMS imaging study
, 2020 Trace elements in pyrite are increasingly being used in ore deposit exploration as a geochemical pathfinder to ore. This is because the trace element systematics of pyrite are sensitive to subtle changes in hydrothermal fluid composition and temperature.

DFT Study into the Influence of Carbon Material on the Hydrophobicity of a Coal Pyrite Surface
Molecules, 2019 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 ...

Iodide interaction with natural pyrite [PDF]
, 2011 29I is one of the major dose-determining nuclides in the safety analysis of deep storage of radioactive waste. Iodine forms anionic species that hardly sorb on the surfaces of common host-rock minerals. Recently, interest has arisen on the role of pyrite,

Plaid‐Like Spin Splitting and Chirality of Magnon Bands in Antiferromagnetic MnTe2
Advanced Science, EarlyView.Helicity‐ and angle‐resolved Raman spectroscopy reveals chiral magnons in the non‐coplanar antiferromagnet MnTe 2. Combined with first‐principles calculations and spin‐wave theory, the results establish its altermagnetic character through circular Raman dichroism, reduced rotational symmetry, and a distinctive plaid‐like momentum‐space magnon spin ...
