Pyrite Mineral Uses and Properties

Pyrite and Coal Mining. Sulfur occurs in coal in three different forms: 1) organic sulfur, 2) sulfate minerals, and 3) sulfide minerals (mostly pyrite with minor amounts of marcasite). When the coal is burned, these forms of sulfur are converted into sulfur dioxide gas and contribute to air pollution and acid rain unless they are removed from the emissions. The sulfide mineral content of the ...

Mining and processing of the raw bentonite may also expose the pyrite impurities to further (oxidation) alteration. Once emplaced in the repository, the pyrite will be exposed to a warm, aerobic phase and may undergo further alteration. Finally, once anaerobic conditions have become established in the repository, pyrite may dissolve and release sulphide ions. The focus of the current review is ...

The Most Dangerous Gases In Mining: Damp Gases

The most effective, safe, and efficient way of keeping mines free of dangerous gases is done through quality mining ventilation systems. Mine ventilation provides a safe flow of air through the workings of a mine at a measurable volume that dilutes and removes any build-up of dangerous gases and other chemical and physical contaminants that may be present, as well as regulating the temperature.
