Pyrite

Pyrite is a cool mineral that forms a range of beautiful and interesting crystal shapes, all with pyrite's distinctive brassy yellow color ( Amethyst Galleries shows examples). It is associated with a range of economically important ore minerals, and it often takes interesting forms in marine sediments. For example, pyrite often replaces ...

Chalcopyrite | Common Minerals

Some Spanish chalcopyrite and pyrite bodies have been continuously mined for over three thousand years to produce copper and sulfur, along with other associated minerals such as gold. More recently, copper's high conductivity, softness, and resistance to corrosion, have given it a critical role in generating and distributing electrical power. ...

What is "Fool's Gold?" | U.S. Geological Survey

Fool's Gold can be one of three minerals. The most common mineral mistaken for gold is pyrite. Chalcopyrite may also appear gold-like, and weathered mica can mimic gold as well. Compared to actual gold, these minerals will flake, powder, or crumble when poked with a metal point, whereas gold will gouge or indent like soft lead. In addition, actual gold will …

Pyrite Chemistry: The Key for Abatement of Acid Mine Drainage

Pyrite oxidation produces extremely acidic drainages (as low as pH 2) enriched with Fe, Mn, Al, SO 4, and often heavy metals such as Pb, Hg, Cd, etc. (Table 10.1). Pyrite oxidation takes place when the mineral is exposed to air and water. The process is complex because it involves chemical, biological, and electrochemical reactions, and varies ...
