Pyrite, Coal, Kentucky Geological Survey, University of Kentucky
Pyrite. Pyrite (FeS 2) is the most common sulfide mineral in coal and a major source of the sulfur in coal. Pyrite can form in peat while the peat is accumulating, or can form in peats from the introduction of sulfate (SO 4) into the peat if the peat was buried by marine waters (such pyrite is called syngenetic or authigenic pyrite).

The crystals form in the Isometric System; cubes, octahedrons, pyritohedrons and combinations of these and other forms. It also may be found in radiating disks, hair-like crystals, concretions and massive lumps in sulphide ore deposits. Pyrite sometimes also contains small amounts of cobalt, nickel, silver or gold.

Cadmium and lead distribution in pyrite ores
The pyrite ores are strategic industrial resources which generally serve as raw material for producing sulfuric acid. However, during the mining and industrial processing activities, associated toxic elements of cadmium (Cd) and lead (Pb) could be released into the surroundings, posing a significant threat to local environment and …

1. Introduction. Tailings from the mining of sulfidic minerals containing metals such as copper (Cu), zinc (Zn), and lead (Pb) represent the largest volume of waste generated in the mining industry in Europe with an annual generation of ∼600 Mtons and a historic stockpile of 28,000 Mtons (Spooren et al., 2020).It has been reported that the …
How does mine drainage occur? | U.S. Geological Survey
Mine drainage is surface water or groundwater that drains from an active or abandoned mine. In some cases, pyrite (an iron sulfide mineral) is exposed and reacts with air and water to form sulfuric acid and dissolved iron. Some or all of this iron can precipitate to form the red, orange, or yellow sediments in the bottom of streams containing ...
Pyrite Mining | The Diggings™
Pyrite mining techniques vary depending on the location and the nature of the deposit. Open-pit mining and underground mining are the two main methods used. The process involves drilling, blasting, and hauling the ore to the surface for further processing. Due to the presence of sulfur, special care must be taken to manage environmental impacts ...

Pyrite is sometimes called Fools Gold because of its similarity in color and shape to Gold. In the old mining days, Pyrite was sometimes mistaken for Gold, as they frequently occur together, although Gold and Pyrite can very easily be distinguished by simple observation and testing of characteristics. Pyrite occurs in numerous shapes and habits.
