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 ...

Gradational development of slaty cleavage to schistosity -an example from the Iberian Pyrite Belt, Spain- [PDF]
, 1994 The Iberian Pyrite Belt is an Upper Paleozoic succession which has been divided into the Phyllite-Quartzite Group, the Volcanic-Sliceous Complex and the Culm Group in ascending order from base to the top. The contacts among them are conformable.

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 ...

Study on Water Wettability Mechanism of Pyrite and Coal Surfaces Based on Density Functional Theory
Kuangchan zonghe liyong, 2022 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

Advanced Science, EarlyView.This study systematically compares the degradation efficiency of CIP in a H2O2‐alone system and a novel Bi12FeO20‐H2O2 photo‐Fenton system. It reveals for the first time the presence of a quinone‐imine intermediate in the H2O2‐alone system, which exhibits toxicity comparable to CIP.
